CV-22 tiltrotor Osprey USAF

Tiltrotor — this aerial vehicles, capable of producing vertical takeoff and landing (as do the helicopters) and long horizontal flight speed, suitable for everyday aircraft. Because the aircraft of this type are not completely no helicopters or airplanes, it affects their view. As a result, the configuration of these aircraft can take the most unexpected kind. In addition, because the aerial apparatus Rata this type are characterized with 2 sharply differing modes of flight in their design but I have to constantly go for a compromise.

CONSTRUCTION.

VTOL vysokoplan made on a straight-wing, two-keel fins, 2 CCD and 2 rotary screws in nacelles at the wing tips.

Fuselage semi-monocoque type with a rectangular cross-section. Fuselage length 17.47m. The design is made of one hundred percent KM (fuselage weight 1500kg). The side skirts are used for cleaning the main landing gear and the placement of additional fuel tanks, air-conditioning systems and equipment. In the front part of the fuselage posted a triple cabin crew, which are installed ejection seats armored to withstand the bullets hit the caliber of 12.7mm and 50g congestion in the longitudinal direction and 14.5g — vertically. On the right side of the fuselage in front of the entrance is a two-piece door, the upper section opens up and inside cabins, and the bottom opens down outside and has an integrated ladder. The cab dimensions 7.37 x 1.53 x 1.3 m, volume 24.3m3 will be able to fit in the seats along the sides of 24 paratroopers with weapons or 12 the wounded on stretchers accompanied by a nurse.

Wing high-lying, with a low angle reverse sweep caisson type with 2 spars and constant chord equal to 2.54m. Almost one hundred percent made of grafitoepoksidnyh CM. The top and bottom skin panel piece construction. Three-section of the wings socks are made of duralumin alloy honeycomb "Nomex". The wing mounted on radial bearing diameter 2.3m, made of stainless steel and provides a turn of the wing along the fuselage when placed on the deck of a VTOL aircraft carriers.

Turning the screws with 3 trapezoidal blades. Root chord of the blade 0.87m, end — 0.56m. Twist blades 45 °. The blades are made of carbon and glass fiber. The design of the hinge blades used elastomeric bearings. The screws have a braking system and folding blades. The screws are connected between a synchronizing shaft, laid inside the wing. Rotating gondolas made using a hydraulic drive with helical gear.

Plumage dvuhkilevoe quite grafitoepoksidnogo made of the material. The stabilizer (5.61m span, the area of 8.22m2) tail fairing mounted above the fuselage. The total area of 2-vertical fins 12.45m2.

Tricycle landing gear is retractable, with dual wheels. Nasal support retracts back into the compartment under the front part of the fuselage. The main bearings are removed in the side skirts. The chassis is designed to fit with a vertical speed of 4.5 m / s. Wheels are the main pillars of the carbon disc brakes. Wheel track 4.62m.

The power plant consists of 2-CCD Allison T406-AD-400, installed in the rotating gondolas on the wing tips together with screws. Turboshaft turbine engine has a 14-stage axial compressor, annular combustor, two-stage gas generator turbine and a two-stage power turbine. Air flow 16.1kg / s, and the pressure increases 14 specific fuel consumption at maximum continuous power mode 0.19kg/l.s.-ch. The engine has a gearbox and a control system FADEC. Length of the motor (gearless) 1.96m, width — 0.67m, height — 0.86m. Dry weight 440kg engine.

Fuel system has 13 compartments of tanks, tank 8645l. Each side fairing of the fuselage in front of a one-compartment tank, right in the fairing at the rear of an additional tank. In the caissons of the wings are 10 tanks of compartments: a pair of outer tank serves as a consumable. On the toe of the right wing refueling nozzle is placed under pressure on the upper surface of each console has one neck filling system by gravity. On the bottom side of the fuselage bow section bar mounting element is provided in flight refueling. For ferry flights in the cargo is likely 2-installation of additional fuel tanks with a total mass of 7235kg of fuel.

System management. To control modes are used for helicopter control system common and repetitive steps of rotating screws. In cruise flight controls are used to cross the two outside elevons for pitch control is a single-section area of 4.82m2 elevator, and for sensible — the rudders on the vertical keels. The drive control surfaces is carried out by means of hydraulic actuators and wire system with triple redundancy.

Lift consists of 4 sections elevons, the outer pair of which is used for lateral control. Elevon area 4.12m2. Drive elevons made using EDSU and steering.

Onboard equipment includes two are independent and one spare hydraulic system operating pressure 350kg/sm2. The structure includes electrical two Alternator (40kVa) two constant current generator (50/60kilovolt-ampere), rectifiers, converters, battery capacity of 15 A * h Socks wings and vertical fins have anti-icing system with inflatable protectors. Windshield glass, front edge vozduhopoglotiteley engines, blades and screws coca have electric heating.

Electronic equipment consists of a navigation system, TACAN, systems, VOR / ILS, VHF radio communication equipment and HF bands, identification systems and other information from the TACAN, VOR / ILS, radar altimeter, vertical gyroscopes displayed on the four color monitor. The cabin has a fifth screen — displaying maps of the area. AN/ARO-174 used radar for flight in a mode of following the terrain, the aircraft was equipped with two computers for processing AN/AYK-14 combat mission, the crew is foreseen for the implementation of systems providing piloting criteria in the night, and helmet-mounted night vision goggles; for warning of an attack missiles air-to-air system has AN/AAR-47.

Armament is dependent on the variant of the VTOL aircraft. Provides space for mounting in the cab of machine guns and 7.62 caliber 12.7mm, and under the nose of the fuselage — turret guns. There are also sites for the suspension of anti-submarine torpedoes, anti-ship missiles and missile air-to-air.
