UNMANNED AERIAL VEHICLE WITH A TURBOJET ENGINE LOCATED INSIDE THE FUSELAGE WITH AN ADDITIONAL RELEASABLE SUSPENDED FUEL TANK CONTAINING AN AIR INTAKE DEVICE Russian patent published in 2020 - IPC B64D37/08 B64D37/12 

Abstract RU 2725014 C1

FIELD: aircraft engineering.

SUBSTANCE: invention relates to unmanned aerial vehicles. Unmanned aerial vehicle (UAV) with turbojet engine (TJE) located inside fuselage with additional dropping suspended fuel tank containing air intake device tank consists of housing (1) with wing and empennage (2), main fuel tank (3) with fuel system (4) and supercharging system (5), TJE (6) arranged inside fuselage, main air intake device (7), additional suspended dropping fuel tank (8) with aerodynamic surfaces (9), with attachment and separation assemblies with housing (10). Additional suspended dropping fuel tank has a coating from radar absorbent material (11), consists of two compartments (12) and (13), each of which contains fuel system (14) and (15), common supercharging system (16) with docking and decoupling (17) assemblies. First (12) is located in front of main air intake device and has additional air intake device (18) connected to main air intake (7) device through seal (19), and compartment (13) is located behind main air intake device (7) and comprises fairing rear (20).

EFFECT: reduction of UAV aerodynamic drag and volume increase.
