IPC: B64C27/04
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To improve operation efficiency of a remote control type helicopter by stopping a rotor in a short time after landing, and shortening standby time up to starting replenishing work of fuel from the landing. SOLUTION: A throttle servomotor 10 is controlled by a control signal from a remote control device. When an engine speed of an engine 2 reduces, a main rotor pitch servomotor 7 is interlocked and controlled, and an arm 7-1 is rotated in the arrow 101 direction so that output of the servomotor 7 is transmitted to a motor-driven brake 6 via a wire 9 rotatably joined to the arm 7-1. The motor-driven brake 6 converts the output of the servomotor 7 into braking force to impart the braking force to a transmission input shaft 4. The motor- driven brake 6 starts braking when the engine speed of the engine 2 reduces up to an engine speed N2 not more than an engine speed N1 only for a centrifugal clutch 1 with a pulley to release the connection of the input shaft and an output shaft, and releases the braking when the engine speed of the engine 2 increases up to the N2.
