Central Aero-Hydrodynamic Institute. Zhukovsky (TsAGI) began implementation of a state contract for carrying out the research and development (R &D) to create a UAV VTOL with a lift fan, said "AviaPort" a source in the aviation industry.
TsAGI for many years working on a research aircraft, including unmanned, new schemes. In these studies, the results obtained sufficient for the development of a promising new type of drone, the source said.
He said the completion of the research provided in 2014. The first drone fan type was built in 2010, the flight was performed including the nature of the demonstration, showing the ability to create full sets of the proposed scheme.
Under the terms of an open competition, the initial (maximum) contract price from the state budget amounted to 51.3 million rubles. In addition, the contractor engaged by extrabudgetary funds should reach 35,222 million.
UAV is a cylinder in the upper part of which is set to "ball" with a target load, below — the electric motor and fan, creating thrust. The device takes off vertically and moves to horizontal flight, using a cylinder as an annular wing.
Odnoventlyatornaya scheme is more complex compared to mnogoventilyatornoy scheme in terms of flight dynamics. When mnogoventilyatornoy scheme, you can create to control raznotyagovost fans, and odnoventilyatornoy involved in the management of the scheme only rudders.
But odnoventilyatornaya scheme is faster and has a greater range, is more compact.
As the power plant UAV VTOL fan type are plans to set up and internal combustion engines, which will increase the weight and size parameters, first of all, by weight of the payload, range.
In the creation of the software auto flight UAV most challenging are transients — the transition from vertical to horizontal flight lift and back. It is these modes are the most difficult to control the drone.
Abroad actively working on drones similar scheme. In Afghanistan, the U.S. used about 50 odnoventilyatornyh devices, but in level flight, these devices do not move.
Central Aero-Hydrodynamic Institute — the largest public research center of aviation and space industry of the Russian Federation, created to solve the problems of fundamental and applied research in the fields of aerodynamics and hydrodynamics, aeroacoustics, flight dynamics and strength of structures of aircraft. TsAGI carries the state examination of all aircraft being developed in the Russian design bureaus, and gives a final conclusion on the feasibility and safety of the first flight. TsAGI is involved in the formation of the state programs of aircraft, as well as in the creation of airworthiness standards and regulations of public documents.
