The invention belongs to the field of a rotor wing wind tunnel test, and particularly relates to a dip angle mechanism convenient for a wind tunnel test. The dip angle mechanism comprises a base plate, a wind tunnel is mounted at the top of the base plate, the top of the base plate is provided with a rotation groove, a rotation plate is rotationally mounted in the rotation groove, the top of the rotation plate is connected with a rotary disk through welding, a rack is fixedly mounted at an external side of the rotary disk, the top of the base plate is provided with a motor slot, a gear motor is fixedly mounted in the motor slot, an output shaft of the gear motor is connected with a gear through welding, the gear is engaged with the rack, and two lateral plates are fixedly mounted at the top of the rotary disk. The dip angle mechanism convenient for the wind tunnel test is simple in structure and convenient to operate, can adjust a dip angle of the rotor wing, can conveniently researchaerodynamic characteristics of the rotor wing under different dip angle conditions through variation of the dip angle of the rotor wing, needs low manufacturing cost, and can assist carrying on of aerodynamic characteristics research under maneuvering flight conditions of a helicopter and aerodynamic performance comparative study under different fixed main axis dip angles.
Description
technical field [0001] The invention belongs to the field of rotor wind tunnel tests, and relates to an inclination mechanism for wind tunnel tests. Background technique [0002] Due to the lack of aerodynamic force, the current conventional configuration helicopter makes it difficult to improve its speed. The high-speed helicopter designed with various advanced technologies such as the concept of forward blades and the tail propulsion device has broken through the forward flight speed limit of conventional configuration helicopters, and its maximum cruising speed has reached 1.5 times that of conventional configuration helicopters; [0003] Compared with foreign countries, domestic research on high-speed helicopters with coaxial rigid rotors is still in its infancy, and the aerodynamic characteristics of the new rotors of this configuration helicopter are not well understood. The aerodynamic characteristics of the case. Contents of the invention [0004] In view of this...
