The invention discloses a low-cost test platform aircraft for rocket recovery technology. The shortcomings of high cost, multiple limiting factors and lack of the corresponding research type recoverytechnology test platform aircraft of an existing recovery technology test aircraft, such as rockets, are overcome. The low-cost test platform aircraft for the rocket recovery technology comprises a test platform, a fuel oil storage tank, at least four supporting legs, at least eight hydraulic cylinders, at least four engine units, a power supply assembly and a control system, wherein a central through hole is formed in the center of a circle of the test platform, and at least four peripheral through holes are uniformly formed in the center of the circle of the test platform; the fuel oil storage tank penetrates through the central through hole of the test platform; the at least four supporting legs are uniformly arranged below the test platform at intervals; every two hydraulic cylinders are arranged on the same supporting leg; the at least four engine units are separately installed in the peripheral through holes; the power supply assembly is arranged on the test platform; and the control system is used for controlling a thrust-adjustable turbojet engine to swing under the driving of a rotating shaft according to the control instruction.
Description
【Technical field】 [0001] The invention belongs to the technical field of aerospace vehicles, and in particular relates to a low-cost test platform aircraft for rocket recovery technology. 【Background technique】 [0002] The design of the rocket's navigation guidance and control (GN&C) system is a key part of the rocket's vertical recovery technology. At present, the feasibility of rocket vertical takeoff and landing technology has been verified, and new GN&C technologies are still being proposed. However, due to the high cost and high complexity of experimental aircraft using rocket engines as the main thrust, many GN&C improvement ideas are in the In the stage of theoretical research, there is no practical verification. There is an urgent need for a low-cost rocket vertical take-off and landing verification platform solution to promote the development of rocket recovery GN&C technology. The existing real rocket vertical take-off and landing verification platform uses rock...
