Filed: 1994-03-10
Abstract: PURPOSE:To prevent sudden drop in engine speed by having such control that the higher is the manipulation speed of an engine controller, the larger becomes the objective engine speed and thereby raising the rate of increase of the engine speed. CONSTITUTION:In controlling engine speed in a wireless steered helicopter for agricultural chemical spray, an inclination angle of an engine control stick in a transmitter 10 is detected by a sensor 24 and the output is sent out to CPU22 contained in the helicopter. Then, an objective engine speed corresponding to the engine control stick manipulation quantity is calculated by an objective engine speed calculation means 27. And then, a control quantity for a servomotor 5, necessary for bringing the present engine rotational frequency up to the objective engine rotational frequency is calculated by a servomotor control quantity calculation means 28. An objective engine speed is obtained by adding an objective rise quantity obtained by multiplying a manipulation angle speed of an engine control stick in an engine control stick inclination angle by a certain constant to a base engine rotational frequency.
