According to the enterprise research app, Jiangsu Deep Blue Aerospace Co., Ltd. recently applied for the publication of a patent for a “deployment drive device for launch vehicle landing legs and a recyclable launch vehicle”. According to the patent abstract, this disclosure relates to the field of recyclable launch vehicle technology, in particular, providing a deployment driving device for launch vehicle landing legs and a recyclable launch vehicle. The unfolding driving device of the launch vehicle landing leg includes a cylinder block, a piston body, and an elastic part; one end of the cylinder block is rotatably connected to the arrow body, and the piston body is rotationally connected to the cylinder body, and the other end of the cylinder block has a piston hole; the elastic part is arranged between the piston body and the cylinder body so that one end of the piston rests on the landing leg under the elastic influence of the elastic part; the cylinder body is provided with a gas supply channel so that the piston is propelled by the gas through the piston hole The cylinder body moves outward to provide thrust to the landing leg in the direction away from the arrow body, that is, for landing The unfolding of the outrigger provides initial thrust, helps the landing leg to unfold smoothly in a timely manner, and ensures the successful recovery of the rocket.
