ANALYSIS DEVICE FOR FIXED WING AIRCRAFT SPIN RECOVERY SYSTEM

摘要

The present invention provides an analysis device for a spin recovery system of a fixed wing aircraft, comprising a parachute installed to be attached to or detached from the tail of the aircraft for spin recovery of the fixed wing aircraft; an attachment and detachment device installed at one side of the tail of the aircraft and mechanically unfolding the parachute at the tail of the aircraft; an unfolding switch part installed in one side of the parachute and controlling the unfolding of the parachute by controlling a function of the attachment and detachment device; and a measurement system installed at one side of the aircraft and measuring and outputting various test values according to the unfolding of the parachute. The present invention designs the spin recovery system having a forceful parachute unfolding switching member for preventing a wrong operation, installs the system in a rotary wing aircraft to make it easy testing a high angle of attack, executes a stability assessment test via measurement equipment and analyzes its result, thereby acquiring test data via a high speed planing test of the rotary wing aircraft, comparing its result with an analysis value to check robustness of the spin recovery system, and to be applied to development of the rotary wing aircraft, so it maximizes stability of the rotary wing aircraft.
