Abstract

The invention provides a device for measuring RCS (Radar Cross Section) jet disturbance force and disturbance moment of a near space aircraft. The device comprises six simple component force sensors, six elastic hinge connecting rods and three adaptive connecting rods, wherein the measurement directions of the three simple component force sensors are distributed along the axis Z of the Cartesian coordinate system and the three simple component force sensors are used for respectively measuring the force along the direction of the coordinate axis Z, the moment along the direction of the coordinate axis Y, and the moment along the direction of the coordinate axis X; the measurement directions of the two simple component force sensors are distributed along the axis X and the two simple component force sensors are used for measuring the force along the direction of the coordinate axis X and the moment along the direction of the coordinate axis Z; the measurement direction of one simple component force sensor is distributed along the axis Y and the one simple component force sensor is used for measuring the force along the direction of the coordinate axis Y; the elastic hinge connecting rods are arranged uprightly, one end of each elastic hinge connecting rod is fixedly arranged at one of the simple component force sensors, and the other end of each elastic hinge connecting rod is fixedly arranged at an upper floating plate directly or indirectly through one adaptive connecting rod. The device is capable of simultaneously measuring the three-component force and three-component moment of the whole RSC under a working state.

Description

technical field [0001] The invention relates to the technical field of near-space vehicle performance detection, specifically, the present invention particularly relates to a near-space vehicle, especially a near-space hypersonic vehicle, RCS (Reaction control system, that is, jet reaction control system) jet disturbance force and interference Torque measuring device. Background technique [0002] When a hypersonic vehicle in near space (20km to 100km from sea level) flies at an altitude above 60km, due to the extremely thin air, the aerodynamic control capability of the control surface is very weak, which cannot meet the attitude control requirements of the aircraft. At this time, RCS control is required. The usual practice is to centrally connect the thrust reversers that control all directions to the bottom shield at the bottom of the aircraft, and improve the ability of the small thrust reversers to adjust the attitude of the aircraft by maximizing the moment arm (to the...
