Title:
FIXED TEMPERATURE MAINTENANCE SYSTEM FOR ENGINE IN UNMANNED AIRCRAFT HAVING AUTOMATIC THROTTLE LIMITING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/111597
Kind Code:
A1
Abstract:
A fixed temperature maintenance system for an engine in an unmanned aircraft having an automatic throttle limiting device, according to the present invention, comprises: an automatic flying device for outputting a throttle command; an automatic throttle limiting device for automatically limiting an upper value of the throttle command that is output by means of the automatic flying device; and a rotary engine for providing the automatic throttle limiting device with feedback on the internal temperature of an engine in the automatic flying device. Therefore, the present invention can be used in any unmanned aircraft, to which an air-cooling rotary engine (reciprocating engine) is applied, enables using of the existing automatic flying device for an unmanned aircraft as is, can have extended life and increased credibility of an engine, and enables recovering of an aircraft without any accident due to the engine even when communication with a ground station is interrupted.
