Abstract

The invention discloses a two-degree-of-freedom simulator of a grid fin aircraft, and relates to an aircraft simulator. A barrel-shaped air duct is fixedly connected to a fan; an X swivel is arranged along the inner wall of the barrel-shaped air duct; a Y swivel is less than the X swivel in diameter; the Y swivel is arranged in the X swivel; the Y swivel and the X swivel are arranged within a same horizontal plane; four bearing seats are uniformly arranged on the upper end face of the Y swivel along a same circumference; two bearing seats are uniformly arranged on the upper end face of the X swivel along a same circumference; a tested object is arranged in the Y swivel; a long connecting rod runs through a transverse through hole and two passing-through holes and two ends of the long connecting rod are connected to the two opposite bearing seats on the Y swivel; the other two opposite bearing seats on the Y swivel correspond to the two bearing seats on the X swivel one by one; and one end of a short connecting rod is connected to the bearing seats on the Y swivel, while the other end is connected to the bearing seats on the X swivel. The two-degree-of-freedom simulator provided by the invention is used for simulating a pneumatic environment of the grid fin aircraft and verifying a dynamical model and a control method of the grid fin aircraft.

Description

technical field [0001] The invention relates to an aircraft simulator, in particular to a two-degree-of-freedom simulator of a grid rudder aircraft. Background technique [0002] Aircraft is a commonly used control object in control disciplines. Aircraft has characteristics such as nonlinearity and strong coupling, and due to the existence of propellers, aerodynamic factors are introduced into the system. So many scholars in the field of control are keen to study this system and apply the designed control law to the system. [0003] Grid rudders are currently a popular method for controlling the flight attitude of a rocket in atmospheric space. As an unconventional space lifting surface, the grid rudder is a honeycomb structure composed of many thin grid walls embedded in the frame, which can obtain a large lift area while keeping the overall size of the aircraft basically unchanged. At the same time, the hinge moment of the grid rudder is very small, and the power of the...
