Sikorsky S-65 and S-80 (H-53)
S-65 has been designed to the requirements of the Marine Corps (ILC) of the United States on a new heavy transport helicopter, which was supposed to replace the aging CH-37 Mojave. Development of S-65 was carried out by specialists of «Sikorsky» on the basis of the project HR3S-1 is a modified version designed by the ship’s helicopter S-61 / SH-3 and featuring a stretched fuselage and a rear cargo ramp. The project also became the basis for the creation of combat search and rescue helicopters and CH-3 HH-3 Jolly Green Giant.
Tactical and technical requirements for the foreseeable future ship heavy transport helicopter HH (X) were unveiled command USMC in 1962. Marines needed a helicopter that can take on board a payload of 3629 kg, with a combat radius of at least 185 km and speed 278 km / h. The helicopter had to have the capacity to carry 1.5-ton truck and trailer, 3f For Hawk or Honest John tactical missiles of class «surface-to-surface».
The company «Sikorsky» offered to tender his helicopter S-65, which combined mission of the flying crane S-64Tarhe, shestilopastny main and tail rotors of the helicopter CH-37 and CH increased Glider-3 with a waterproof casing, the rear cargo ramp and side sponsons.
The prototype twin-engine S-65 helicopter was flight tested in 1964, and soon adopted USMC enrolled heavy transport helicopter CH-53 Sea Stallion. It was built in four basic versions: CH-53 transport, search and rescue HH-53 Mine (helicopter-sweeper) RH-53 and helicopter for special operations MH-53. Modifications of the CH-53 and HH-53 is widely used by the Commission and the US Air Force in Vietnam.
Subsequently, the company «Sikorsky» helicopter developed a second-generation S-80, where its experts found the third dvigatelT64i seven-bladed rotor.
In 1973, the company signed a contract to build two prototypes of a new type of machines and their testing. USMC eventually got upgraded heavy transport helicopter CH-53E and Navy — Mine helicopter MH-53E Sea Dragon. Helicopters CH-53A / D and CH-53E aircraft USMC actively used during operations «Iraqi Freedom» and «Enduring Freedom». The operations in Afghanistan were also involved German helicopter CH-53G.
In 2008, the US Air Force decommissioned its last helicopter Special MH-53M Pave Low (Enhanced Special Operations), and the year before USMC launched a decommissioned helicopter first generation of CH-53A / D — to replace them came tiltrotor the V-22.
As of the 2013 modified military helicopter S-65 remained in service with Iran, Israel, Mexico and Germany. The company «Sikorsky» commissioned by the USMC began to develop a new generation of helicopters, the designation CH-53K.

Sikorsky S-67 Blackhawk and S-72
In the mid-1960s. Company «Sikorsky» proposed in the tender announced by the US Army for a new high-speed combat helicopter, the project, designated S-bb. In competition he lost AN-566 Cheyenne company «Lockheed», but «Sikorsky» project later used as a base for creating a landing, but Assault Helicopter S-67 Blackhawk. Helicopter S-67 was created by its own initiative, and is equipped with two ADTA General Electric T58-GE-5 with a capacity of 1500 liters. s., and a five-blade main and tail rotor from the S-61. The helicopter had a narrow fuselage, characteristic ganshipa, small wing span (8,3V m), cross-shaped tail with a controlled stabilizer and retractable landing gear with a tail wheel.
Helicopter S-67 differed good maneuverability, it has been flight tested on August 20, 1970 and December 14, 1970 established in its class a new world record speed of 348.971 km / h (at a distance of 3 km). The development of the helicopter was discontinued after only one prototype crashed at an air show in Farnborough in 1974.
Under a contract with NASA and the US Army company «Sikorsky» also built two S-72 Rotor Systems Research Aircraft (RSRA), which are used as high-speed helicopter pilot for testing the various options rotors, transmissions and power plants. The design of the S-72 was used a modified glider S-67, as well as a new wing span 13.74 m and a tail unit. The power plant consisted of two ADTA General ElectricT58-GE-5 with a capacity of 1400 l. from. and two auxiliary turbojet GETF34-GE-400A thrust of 41.26 kN.
The wing and auxiliary TRD which were suspended one at each side of the fuselage, allowed testing helicopter rotors, are too small to raise independently S-72 into the air. The first flight of S-72 was held October 12, 1976. The helicopter is also planned to involve working out the concept of the rotor — wing: with rigid rotor blades to be used in flight as an X-shaped wing. In flight, the propeller stopped and worked already as surface- aerodynamic wing. The conversion machine was completed in 1986, but since the end of 1987, spent only four test flights, and in 1988 the program was closed.
Sikorsky S-69 / XH-59A
In 1972 the company «Sikorsky» developed for the US Army experimental helicopter S-69, which had to work out the concept of long-term rotor (Advancing Blade Concept — the concept of advance of the blade), include two three-blade rigid counter-rotating screws. S-69 was not equipped with tail rotor and a conventional tail stabilizer with a spaced keels with rudders. It was equipped with Pratt ADTA & Whitney Canada PT6T-3TurboTwin Ras capacity of 1825 liters. from. and two auxiliary turbojet Pratt & Whitney J60-P-3A thrust of 13.34 kN on either side of the fuselage.
The first of two XH-59A (denoted by the US Army) has been flight tested on July 26, 1973, but soon it was damaged, so that the tests continued on the second prototype. Helicopter demonstrated a maximum speed of 296 km / h in the embodiment of the flight in the helicopter and 488 km / h in flight using the side turbojet. During the tests revealed problems with a strong vibration and under effective management. The last flight took place in 1981, just a helicopter flew 106 hours.
Soon «Sikorsky» proposed a new modification of the helicopter, which was designated XH-59B, and features an advanced rotor, the new power plant and tunnel pusher propeller on the tail. However, the proposal did not interest among customers caused.
Sikorsky S-70, UH-60 Black Hawk and SH-60 Seahawk
Sikorsky S-70, UH-60 Black Hawk and SH-60 Seahawk
The family of helicopters S-70 was created by «Sikorsky» to replace are in service with Bell UH-1. The relevant tender US Army announced in 1972 to develop a multi-purpose tactical transport helicopter UTTAS (Utility Tactical Transport Aircraft System). «Sikorsky» unveiled a prototype YUH-60A, fly around October 17, 1974 and featuring a spacious cabin with moves back door, two-seat cockpit and reinforced chassis. The helicopter was equipped with a four-bladed rotor and two engines T700-GE-700.
The helicopter was very attractive and, most importantly, tenacious, so in December 1976 «Sikorsky» was declared winner of the tender, which was also involved helicopter Boeing Vertol YUH-61.
The first production UH-60A Black Hawkjiofl flew on 17 October 1978, and his first adopted in June 1979 received a 101st Airborne Division.
As standard, the helicopter takes on board (except the two pilots) single arrow (firing of gun-board), and the paratroopers, although, if necessary, in the cabin can accommodate up to 20 people. During the years of service helicopter repeatedly passed modernization, received vysokoustanovlennoe wing with four pylons for the suspension of fuel tanks or weapons, the ability to place on-board medical evacuation kit or set for winter operation, a rescue hoist, machine guns M134 Minigun or M60, cutting equipment cables, screen-exhaust device (EVU) in the nozzle engines and advanced avionics and on-board defenses.
The US Army has received a serial UH-60A and the first to distribute them into groups of troops in Europe and Korea, and only then they began to enter the compound deployed in the continental United States. With the installation of new equipment in the helicopters grew its mass and power unit became less effective. As a result, it was decided to create a less expensive version of the UH-60L more powerful. motors T700-GE-701C, which allowed him to levitate military HMMWV multipurpose vehicle with ATGM TOW first UH-60L was flight tested on March 22, 1988, deliveries began in October 1989.
The third major version of the UH-60M helicopter appeared in 2006.
On the basis of the Army UH-60 created a lot of modifications, including medical evacuation UH-60Q, helicopter EH-60 electronic warfare system to the Quick Fix and the MH-60K «Velcro Hawk» for search and rescue and special operations. The US Air Force acquired for combat search and rescue operations and to provide special forces MH-60G Pave Hawk and HH-60G Rescue Hawk, and USMC-VH-60N «Presidential Hawk». In addition, some helicopters produced under the designation S-70A. Production was carried out under license in Australia, South Korea and Turkey. S-70C designation applied to civil Black Hawk.
On the basis of the Army UH-60 was developed as a variant SH-60 Seahawk (corporate designation S-70B), which won the tender for the US Navy helicopter, designed for deployment on ships of classes «frigate» / «Destroyer» and equipped with a system LAMPS III (Light Airborne Multi-Purpose System). The main objective was the ASW helicopter — it was to provide antisubmarine naval forces targeting data. First YSH-60B flight tested on December 12, 1979, and the first series SH-60B flew on February 11, 1983.
Structurally, the ship’s option on 83% is compatible with the Army UH-60A, but had a number of significant differences, including corrosion protection airframe and engines T700-GE-401, as well as a system of forced landing RAST (recovery assist secure and traverse).
To solve the problems PLO also developed SH-60F Ocean Hawk, which had significant differences from the SH-60B. SH-60F intended to replace a part of carrier-based air wings SH-3H. They solved the problem of the PLO in the near zone, cargo and personnel, as well as the rise of the water pilots.
In general, similar to the SH-60F HH-60H appeared Rescue Hawk — adopted by the US Navy helicopter to solve the problem of combat search and rescue and evacuation of downed pilots from the battle area. The US Coast Guard operates the HH-60J Jayhawk, are generally similar to the HH-60H Rescue Hawk aircraft of the US Navy.

Sikorsky S-76 Spirit
In the wake of the great success that accompanied JetRanger helicopter company «Bell», «Agusta» and «Bell» brought to market more sophisticated machines A109 and Model 222. At the same time «Sikorsky» within the framework of a similar concept has created several more 8/12-seater multipurpose twin-engine helicopter S-76. In his design embodied various achievements obtained in previous projects, in particular, the support system has been established on the basis of similar to the S-70.
The first prototype S-76 flew on March 13, 1977 and was equipped with ADTA Allison 250-C30 capacity of 650 liters. s., and in 1982 went into production modernized S-76 Mark II. After the modernization of power plant appeared 76A-S + and S-76A ++.
June 22, 1984 rose in the air the first S-76B, equipped with two Pratt ADTA & Whitney RT6V-36A with capacity of 981 hp, and May 18, 1990 has been flight tested version of the S-76C. The latter option, as well as S-76A, are made available to customers and to modify the engines Turbomeca Arriel 1S1 capacity of 732 hp Upgraded S-76C + was equipped with more powerful Arriel 2S1. Since 2006, he was replaced by S-76C ++ with the Arriel 2S2.
Until 2011, built more than 800 S-76. The spacious cabin allows the S-76 helicopter to solve a wide range of tasks: corporate transport, maintenance of offshore oil fields, police and others.
Utility S-76 — a military variants S-76 Mk II. AUH-76-stroke version, featuring an optional sliding doors, armored, airborne defense and the ability to use various weapons, including a machine gun and container blocks NAR, anti-tank and various sighting equipment.
Specialized military option was the S-76B N-76 Eagle, which is generally identical in features AUH-76 but also set different weapons in doorways, modified transmission and reinforced construction.
Military customers are actively bought and civilian S-76, especially in the embodiment of VIP-transport. Among the customers — the Philippines, Chile, Dubai, Guatemala, Honduras, Iraq, Jordan and Spain.
In July 1984 «Sikorsky» Flied single instance of S-75, which was developed within the framework of ACAP (Advanced Composite Aircraft Program), implemented by the US Army and involves the creation of a helicopter with the extensive use of composites in its construction.
The design of the S-75 company managed to successfully integrate Gear ADTA Allison 250-C30S and rotor from the S-76 to the new airframe. Moreover, compared to the conventional S-76 designers have to provide a weight savings of 20%. Active use of composites has become one of the major achievements in the framework of the project the Army light helicopter LHX, based on which the company subsequently «Boeing» and «Sikorsky» was created reconnaissance attack helicopter RAH-66 Comanche.

Sikorsky S-92 Helibus
The S-92 was originally considered as an enlarged version of S-70. The development of the S-92 was launched «Sikorsky» in 1995, but work on the scheme was risk-sharing partnership with the companies «Mitsubishi», EMBRAER, «Gamesa» and «Jingdezhen».
The design of the S-92 embodied a variety of structural elements and systems borrowed from other projects or developed on their basis, including the S-70. Among them — the digital flight control system, cruise control and four-gear — three-stage version of the gearbox of the helicopter Black Hawk. Ball screw screw- smaller version of S-70 helicopter, with composite blades a few more chords and tapered ending, with a sweep angle of the leading edge 30 °, has a similar titanium main rotor hub with elastomeric joints.
The S-92 was generally similar in configuration to the S-65, but had differences — vysokoraspolozhenny and shifted to the left side from the stabilizer strut, vysokoraspolozhennuyu tail boom and the rear cargo compartment door and two-step ramp. Cabin in the basic version is designed for civilian 19 passengers or up to three cargo pallets LD-3.
The first prototypes of the four S-92A was flight tested on December 23, 1998, it was equipped with two engines CT7-6D capacity of 1750 liters. from. Serial machines were equipped with more powerful engines ST7-8. The first deliveries to customers implemented in 2004 — was the recipient of serving the offshore oilfields of the company PHI.
«Sikorsky» developed and the military version of the helicopter H-92 Superhawk, is equipped with powerful engines and ST7-8S able to carry up to 22 soldiers in full gear. Options for the H-92 offered in two tenders, but to no avail. First, HH-92 Superhawk, planned to be used as a combat search and rescue helicopter US Air Force, and the second, VH-92 was considered as a candidate for the new presidential helicopter. As a result, greater success is accompanied by a CH-148 Cyclone — 28 machines of this type acquired for the military-sea-tion Air Canada, the first deliveries under the benchmark tests were performed in 2012.

Sikorsky S-300 series (Schweizer Models 300 and 330)
In 1983 «Schweizer Aircraft Corporation» acquired the rights to produce light helicopters Hughes Model 300C, and in 1986, the rights to the entire line. At that time, a total of 2800 have already been released this family of helicopters.
The first helicopter Model 300C built «Schweizer», flew in June 1984, after which came into production a few more options. Among them were the military training helicopter dual TN-300C, 300C Model Police Sky Knight with armored seats and a searchlight, and the Model 300QC. The company «Schweizer» Model 300C helicopters built in the form of training for the US Army Aviation and Turkey, as well as the TH-55C for the Thai Army (1986). Under the license as a helicopter built — under the designation NH-300C — Italian «Breda Nardi».
Turboshaft (turbine) version of Model 300 was flight tested in 1988 and received the designation of Model 330. It was intended for civilian customers and features a new streamlined fuselage and cabin for four people. Under the requirements of the US Army for a new educational and trenirovoch-tion helicopter was designed with a triple control option, designed for the instructor and two students. But success here is not accompanied by the manufacturer.
In 1997, the air rose Model 330SP, equipped with an advanced rotor and engine Rolls Royce 250-C20W, on the basis of which later developed variant of Model 333. In collaboration with «Northrop Grumman» on the basis of the piloted helicopter model -330SP / 333 has been designed multipurpose drones under the designation MQ-8B Fire Scout entered service with the US Armed Forces.
In August 2004, the company «Schweizer» was absorbed «Sikorsky», and in 2009 Helicopter Model 300 was introduced under the new brand — Sikorsky S-300 (Model 333 was the S-333). The latest development of the company in the family is a helicopter Sikorsky S-434, which is equipped with four-bladed rotor.

August 27, 2008 the company «Sikorsky» flew the prototype of an experimental high-speed helicopter X2, equipped with coaxial rotors and six-bladed tail rotor push. Among implemented in new technological solution-X2-onnaya elektrodistantsi flight control system, a coaxial rotor blades are rigidly secured, the active vibration reduction system, rotor head aerodynamic fairing, which reduced the aerodynamic drag at high flight speeds, and integrated APU. The helicopter is equipped with one ADTA T800-LHT-801.
Flight tests of X2 conducted in four stages, and one of the main objectives was to achieve flight speed of 250 knots (463 km / h). July 26, 2010 X2 has a top speed 417 km / h and unofficially broke the speed record for helicopters, established in 1986, specially the modified Westland Lynx, and September 15, 2010 — and reached a speed of 250 knots.
The last flight of the flight test program X2 made July 14, 2011, incident in 23 flights for a total of 22 hours. Experts «Sikorsky» use the experience gained during the program X2, in the creation of high-speed-enforcement scouting-attack helicopter S-97 Raider.
