Embodiment Construction

[0031] Such as figure 1 As shown, this type of aircraft is a new type of aircraft, which is characterized by long and narrow wings. This type of aircraft is different from current various types of aircraft. However, the aircraft with this type of structure has its own unique characteristics, so it is a development trend in some fields at present. To complete the finalization of the aircraft, it is necessary to test its aerodynamic indicators, and wind tunnel tests are essential. link.

[0032] figure 1 The model in is installed with a scale-down loading test device, in order to complete the fixation of the wing itself and ensure that it is not affected by external forces during the blowing process. Therefore adopt to put a wing cover on the wing, the inside of this cover is hollow structure, can make the wing cover wear on the wing. However, in the blowing process, in order to ensure the uniformity of the force on the wing, the wing cover cannot be in contact with the wing...

Abstract

The invention discloses a double-body super-high aspect ratio aircraft wind tunnel force measurement test supporting device, which comprises an aerofoil ladle cover, a balance ladle cover and a lever balance, wherein the balance ladle cover is of a cylindrical structure with both ends, one end of the balance ladle cover is connected with the aerofoil ladle cover, and the balance ladle cover and the aerofoil ladle cover are integrally arranged; the balance ladle cover and the aerofoil ladle cover are each of a hollow structure, and the hollow structure in the balance ladle cover is vertically communicated with the hollow structure in the aerofoil ladle cover; and the other end of the balance ladle cover is provided with a joint to be connected with a supporting rod. The double-body super-high aspect ratio aircraft wind tunnel force measurement test supporting device firstly solves the fixing problem of a high aspect ratio aircraft model during the test in a wind tunnel, and can ensure that the test on the model can be effectively finished during the wind tunnel wind blowing test because of the unique nature of the device structure; and the double-body super-high aspect ratio aircraft wind tunnel force measurement test supporting device avoids the problem that test results cannot be obtained finally because the test environment is destroyed by adopting the existing test method.

Description

technical field [0001] The invention relates to the field of aerodynamics, in particular to a support device for a wind tunnel dynamometer test of a twin-body super large aspect ratio aircraft. Background technique [0002] Near-space solar-powered aircraft is a new concept of near-space aircraft. At present, its power source is generally solar energy, so it is called near-space solar-powered aircraft. The flight altitude of this kind of aircraft is between 20km and 30km, making full use of the characteristics of strong solar radiation and low wind speed in the high-altitude stratosphere atmosphere, and can fly higher and longer. It is low-cost, flexible, and can fly in a circle over a certain area, or fly globally as needed, which helps to solve the problems of limited flying height and endurance of traditional air platforms. This type of aircraft can stay in the air for a long time for military reconnaissance. It can search, intercept and analyze the signals sent by the e...
