Claim 0:
1. A hybrid flight vehicle, comprising:
a frame;
multiple rotors attached to the frame and configured to produce propelling force to propel the frame;
a gas turbine engine attached to the frame and configured to drive the rotors by combustion when fuel is supplied in a combustion chamber;
a generator connected to an output shaft of the gas turbine engine and configured to generate electric power;
a battery configured to store the electrical power generated by the generator;
multiple first electric motors each connected to the rotors to drive associated one of the rotors by the electric power supplied from the battery;
a second electric motor connected to the output shaft of the gas turbine engine to motor the gas turbine engine by the electric power supplied from the battery;
an engine temperature detector configured to detect a temperature of the gas turbine engine;
a lubricant temperature detector configured to detect a temperature of lubricant of the gas turbine engine;
a battery residual detector configured to detect a residual of the battery; and
a control unit configured to control flight by regulating driving of the multiple rotors by either or both of the first electric motors and the gas turbine engine;
wherein the control unit stops supply of the fuel to the gas turbine engine when the residual of the battery detected by the battery residual detector is equal to or greater than a predetermined value, and supplies electric power to the second electric motor from the battery to motor the gas turbine engine while stopping supply of the fuel to the gas turbine engine when the temperature of the gas turbine engine detected by the engine temperature detector is equal to or higher than a predetermined temperature, and when the temperature of the lubricant of the gas turbine engine is equal to or lower than a predetermined lubricant temperature.
