AIRCRAFT (VERSIONS) Russian patent published in 2015 - IPC F42B15/36 F02K9/78 F41F3/04 

FIELD: aircraft engineering.

SUBSTANCE: aircraft has a hull with a pressure shell, power frames attached to a shell and the units fixed on power frames including the starting propulsion system with a jet nozzle attached to the hull by the device designed with a possibility of fastening release, and a control system. In the first version the starting propulsion system is located in a front part of the hull of the aircraft, and its jet nozzle is designed as a nozzle unit comprising the jet nozzles located on its lateral surface with an inclination of a longitudinal axis of each jet nozzle at an angle 10-30° to a longitudinal axis of the hull. The protective fairing of front part of the hull made from heat-resistant material is attached to the starting propulsion system under its jet nozzles. In the second version of the aircraft it is placed in the transport and starting barrel (TSB) fitted with the device of partial aircraft move with release of the nozzle unit from his cavity. In the third version TSB cover is designed as a protective fairing of the front part of the hull from heat-resistant material and attached to the starting propulsion system under jet nozzles of the nozzle unit.

EFFECT: higher reliability.
