Embodiment Construction

[0023] see figure 1 , is the miniature aircraft experimental device of the present invention, and is made up of two parts: support and rotating tray. Wherein, the support consists of a vertical support 1, a beam 2 and a fixed base 7. The fixed base 7 is fixed on the ground or other planes with bolts. The bottom of the vertical support 1 is fixedly connected with the fixed base 7, and the middle part of the crossbeam 2 is provided with a fulcrum 4, which is connected to the top of the vertical support 1 through the fulcrum 4, and the crossbeam 2 can rotate in the horizontal plane and in the vertical plane through the fulcrum 4. As shown in Figure 3, wherein, Fig. 3 (a) is the sectional view of fulcrum 4 along the crossbeam 2 direction; Fig. 3 (b) is the sectional view of fulcrum 4 along the vertical direction of crossbeam 2, in the figure: vertical support 1, crossbeam 2 , Bolt 41, Bolt 42.

[0024] There is a male thread on one side of the beam 2 on the outer circumference,...

Abstract

The invention discloses a micro air vehicle experimental device and relates to experiment and measurement technology. The device can be used in an air vehicle experiment and parameter measurement and consists of a support, a pallet capable of rotating in three dimensions, a movable balance weight and a safety limit element. The support consists of a cross beam and a support rod, wherein the crossbeam and the support both have fixing holes and fixing bolts so as to be fixed on a horizontal plane to ensure the stability of the experimental device. The rotating pallet is used to carry the air vehicle receiving experiment, the air vehicle can be fixed on the pallet through a bolt, and the pallet and the air vehicle can rotate on three vertical axes in space under the drive of a spherical joint. The experimental device of the invention is designed with the attitude motion and the degrees of the freedoms of motion and position in the three dimensions of the body of the air vehicle according to the spaceflight characteristics of the air vehicle and realizes flight experiment and the measurement of static and dynamic parameters of the air vehicle under the condition of ensuring the safety of the air vehicle.

Description

technical field [0001] The invention relates to the technical field of experimental measurement, and is an experimental device used in various flight simulation experiments of micro-aircraft to obtain flight characteristics and control quality of the aircraft. Background technique [0002] A micro-aircraft refers to a helicopter with a rotor diameter of about 1 meter to 2 meters and a body weight of less than 20 kilograms. The aircraft here refers to helicopters, and micro-aircraft is not suitable for fixed-wing aircraft; the experimental device of micro-miniature aircraft is to use a movable, specially designed mechanical device to fix the aircraft on the device. Within a limited range, it is a flight device that simulates the free flight of an aircraft or a certain flight condition. The purpose of the test device is to perform detection and measurement experiments on a designable flight state on the premise that the aircraft is not damaged, so as to obtain The static or d...
