For the launchers with high recoil mass which use liquid pneumatic recoil machine,fixing the initial pressure of gas is difficult to adapt to all firing angle conditions.In an effort to study the au-tomatic adjustment technology of air pressure adjusting to the change of firing angle,the force on the recoil part combined with the pitching part model of a rail gun with high recoil mass was analyzed,the differential equations of recoil motion was established,the recoil law under typical firing angle condi-tions was simulated,and the recoil effectiveness under constant initial pressure and variable initial pressure strategies was compared.Then,an adaptive air pressure adjustment system was designed and the pressure adjustment test research was conducted.It is concluded that,compared with the constant initial pressure strategy,the variable initial pressure strategy can achieve higher anti-recoil efficiency,and that it is feasible for the launchers with high recoil mass to adjust the volume of the air chamber directly and realize the pressure adjustment indirectly.This study has a certain reference value for the overall design of the launch system of the launchers with high recoil mass.
