The invention discloses a jet flow control device for aircraft model flight test and a test method thereof, and belongs to the field of aircraft test. The control device includes a driving motor, a motor mounting seat, a coupling, a valve adapter shaft, a valve mounting seat, a valve body and a valve core, and the valve core is a V-mouth ball core whose inlet area does not change with the rotation of the ball core. Based on this device, a use strategy of jet control and traditional control rudder combination is developed. Compared with the traditional proportional flow control device, while ensuring the high-frequency and large-flow proportional control requirements, the energy loss is lower, the proportional control response speed is higher, and the pipeline flow stability is better. The strict requirements of load weight volume and jet control accuracy during aircraft model flight test can be met, and the control efficiency of jet control measures can be verified by aircraft model flight test.

Friction plate pair with oleophobic grooves and wet clutch
The invention discloses a friction plate pair with an oleophobic groove and a wet clutch, the friction plate pair comprises a friction plate and a dual steel sheet, and the friction plate and the dual steel sheet are mounted in a matched manner; a plurality of radial grooves and circumferential grooves which are communicated in a staggered mode are formed in the two side faces of the friction plate or the dual steel plate, the radial grooves divide the circumferential grooves into a plurality of fan-shaped sections, the groove depth of the circumferential grooves and the radian value of the positions where the circumferential grooves are located change periodically, a linear relation is formed in each fan-shaped section, and the radial grooves and the circumferential grooves are communicated in a staggered mode. The groove depth and the radius of the radial groove are linearly related, and the groove depth of the radial groove is larger than that of the circumferential groove. According to the invention, the groove depth is gradually increased, so that the speed gradient can be reduced, the oil shearing force is reduced, the oil film shearing heat is further reduced, the belt discharge torque is inhibited, and higher reliability and longer service life are provided for long-term use of the wet clutch.

Valve for improving flow stability and mass flow controller applying same
The invention relates to the field of valves, in particular to a valve capable of improving flow stability and a mass flow controller applying the valve. The valve comprises a flow inlet block, a lower sealing piece, an upper sealing piece, a horizontal guide elastic piece and a control rod. The flow inlet block is provided with a flow inlet and a containing cavity. The lower sealing piece is located in the containing cavity and provided with a plurality of inflow channels, the lower sealing piece is further provided with a matched inclined face, and the matched inclined face inclines outwards from bottom to top; the upper sealing piece is fixedly connected with the inflow block and provided with a plurality of outflow channels, the outflow channels and the inflow channels are staggered, the horizontal guide elastic piece comprises a circular ring part and at least three protruding parts, the circular ring part is arranged outside the lower sealing piece in a sleeving mode at intervals, and all the protruding parts are evenly distributed in the circumferential direction of the circular ring part and protrude out of the circular ring part inwards in the radial direction. And all the convex parts are in contact with the matching inclined surface so as to apply pre-tightening force to the lower sealing piece. It can be guaranteed that the lower sealing piece and the upper sealing piece are kept horizontal in the opening process and after the valve is opened, and therefore stable flow is guaranteed.
