I propose development of a hybrid flight system ‘Barone’, which is combined a balloon with a drone. Barone can be expected as a flight system that combines the advantages of both the stability of the balloon and the good operability of the drone. In addition, Barone can be applied not only as a new flight system, but also for short-term microgravity experiments, air launch to orbit, exploration of the planet with atmosphere. Particularly, Barone can be expected to play an important role in the life exploration on Mars.

This paper studies the separation flow reduction effect around NACA0015 airfoil using PSJA. We expect to reduce fluctuations of wake velocity by PWM control input applied to PSJA using DFC. This paper shows change of the lift force by the DFC in 5m/s main flow velocity and 15deg angle of attack. We attempted two modes by setting 4msec delay time of DFC. DFC positive mode set to ON the PWM signal when the input exceeds the threshold. DFC reverse mode set to ON the PWM signal when the input falls below the threshold. The experimental results show that the DFC result with a delay time of 4ms recovers lift force compared to without control of PSJA. In the both modes 4msec delay time, lift force is maintained without depending on the threshold at 1 second driving start. At the threshold 0.01 of the reverse mode, lift force is kept than the other threshold.
