Abstract: Aiming at the launch of the folding wing aircraft and the performance of the folding wing mechanism, the effects on the vehicle from the cylinder performance of the main factors were studied, of the aircraft from the cylinder process has carried on the stress analysis, analysis of the effects on the vehicle from the cylinder performance of the main factors. The establishment of the aircraft from the cylinder process theory model and ADAMS simulation model, on aircraft leaves the tube during the bow angle changes, from the cylinder and from the cylinder speed, from the cylinder maximum stress, folding wings start time and folding wing expansion synchronization parameters were calculated. The comparison and analysis of the results by the two methods were obtained; the firing angle of the aircraft from tube in bow angle and contact force effect was analyzed. Experimental results show that the two calculation methods for computing the error is less than 5% can be mutual authentication; emission level aircraft from the cylinder head angle to 0.49 degrees, from the barrel of time for 163 ms, off the cylinder speed for 14.12 m/s; with the emission angle increase aircraft from the cylinder head angle decreases, from the cylinder maximum impact force is reduced. The calculation results for vehicle emission properties provide a theoretical basis.
