where the gas generator is installed. High-pressure cold gas injection method is
used to generate lateral force.
The lateral force control device of a certain type of aircraft requires thrust
F ¼ 5 $ 8 N, working time t ¼ 0:5 s, using straight tube injection (non-Laval tube).
Figure 10.11 shows the principle of thrust experiment. The high-pressure air source
passes through the pressure reducing valve and enters the experimental chamber to
eject the cold air. The air source is supplied by the ground cylinder. The experimental cabin is connected with the ground cylinder by connecting pipes, adapters,
