Title:
FLYING OBJECT FLYING BY ELECTRICALLY-DRIVEN AIR TURBO FAN ENGINES
Document Type and Number:
Japanese Patent JP2019163017
Kind Code:
A
Abstract:
To provide a flying object which does not have disadvantages of conventional helicopters capable of performing a vertical flight by rotating a rotor using a gas turbine engine and decelerating rotation thereof: that the gas turbine is heavy and expensive; and that flight depending on only one main rotor is risky because failure of the main rotor will instantly cause crash.SOLUTION: The time has come when automobiles are driven by electricity, and soon the time will come when aircrafts are driven by electricity, as well. To fly for long hours, fuel cell generation is to be used to obtain electric energy for flight. Rotating turbo fan engine (1) by respective electric motors (15) can finely control output with high reliability, and the fuel cell generation produces no harmful exhaust gas. Electricity can be obtained from fuel cells (3) with a suitably selected number of cells. Four fans can be rotated by respective electric motors to allow a light flying object to fly quietly and safely. Thus, electrically-driven flight may become possible and the new generation flying object can be provided.SELECTED DRAWING: Figure 1
