Abstract

The present invention discloses an aircraft support device of an aircraft formation flight experiment and a transonic speed wind tunnel experiment device. The support device comprises: a pedestal fixedly arranged at the bottom portion of a wind tunnel experimental section; a back stay support comprising a first connection arm and a second connection arm, wherein the first connection arm and the second connection arm are connected at an angle, the first connection arm is fixedly connected with the pedestal, and the second connection arm is connected with a lead aircraft through an angle-variable block; the angle-variable block comprising an installation portion and an angle-variable plate connected with the lead aircraft, wherein the angle-variable plate is connected with the second connection arm; and a bent-tail connection rod having one end connected with a grid force measurement mechanism in the wind tunnel experimental section and having the other end connected with the six-degree-of-freedom scale through a scale pole, wherein the six-degree-of-freedom scale is connected with a wing plane. The aircraft support device of the aircraft formation flight experiment and the transonic speed wind tunnel experiment device realize firm support of the lead aircraft and control of the wing plane flight state in the wind tunnel experiment of the aircraft formation flight so as to improve accuracy of a wind tunnel experiment at the aspects of large-scale aircraft formation flight efficiency assessment and formation parameter optimization.

Description

technical field [0001] The invention relates to the technical field of aircraft formation flight, in particular to an aircraft support device and a transonic wind tunnel experiment device for an aircraft formation flight experiment. Background technique [0002] Increasing lift and reducing drag is the eternal pursuit of fluid mechanics researchers and aircraft designers, and drag reduction is also consistent with today's pursuit of environmental protection, fuel economy and other flight goals. Drag directly affects the load capacity and fuel carrying capacity of the aircraft, thus affecting the performance and economy of the aircraft. [0003] Aircraft formation flying involves two or more aircraft flying in formation, which has the effect of significantly reducing drag. When flying in formation, the wake vortex of the aircraft flying in front has a huge impact on the safety of the aircraft flying behind. When the rear aircraft enters the wake area of ​​the front aircraft,...

Problems solved by technology

[0004] However, in the existing wind tunnel experiments, there is a lack of solid support for the lead aircraft and control of the flight status of the wingman, resulting in a large deviation between the existing wind tunnel experiments and the actual formation flight, which affects the evaluation of large aircraft formation flight performance and performance in wind tunnel experiments. Accuracy of formation parameter optimization
