In order to solve some difficulties on the balloon recovery system with a conventional parachute, a recovery system with a parafoil for the controlled-descent was designed and basic on-board system was developed for the real flight operation in near future. Simulating flights from small balloons, six flight tests from an aerial vehicle were carried out to evaluate its capability of the trajectory control and to measure its short term gliding ratio. Through the series of the tests, the system was validated and the averaged short term gliding ratio for about 5 s was measured to be larger than 3.
