Abstract:
Flight tests for an integrated ducted rocket were carried out successfully following ground tests in order to investigate the performance of the ducted rocket.The data obtained have shown that the performance of the ducted rocket is satisfactory.The ducted rocket worked well with excess oxidizer coefficient ranging from 0.8 to 2.3.Its maximum specific impulse is 6.62 kN·s/kg.It demonstrated that the design for both the engine and vehicle is correct.
