Design and Evaluation on Flight Quality Test of Airdrop Mission Based on the Model
In the process of heavy load airdrop flight test,the movement of cargo will lead to excessive changes of aircraft atti-tude,which affects flight safety.In order to ensure the safety of heavy load airdrop flight test,a mathematical model of the airdrop system is built to predict aircraft response during airdrop process,the"prediction validation comparison prediction"method is used to gradually guide flight tests,analyze the aircraft's response characteristics with cargo airdropping before airdrop test flights,deter-mine the flight quality and test flight of the carrier platform,and evaluate the quality of airdrop flight as a prerequisite for airdrop flight testing.The research on airdrop flight design is conducted from two aspects:the section of test flight states and the control methods of test pilots,The aircraft attitude control is taken as the target to determine the test flight status of the gravity airdrop and extraction airdrop,give the pilot manipulation suggestions,design the table of airdrop process evaluation elements,and achieve the flight quality flight test design and evaluation technology for the airdrop mission.The proposed design and flight quality evaluation method based the model provides a technical support for the execution of airdrop missions,and fully evaluate the flight quality of air-drop missions.
