Description

Technical Field

[0001] This utility model belongs to the field of aircraft test equipment design technology, and specifically relates to a clamping device for a trajectory capture test measurement platform. Background Technology

[0002] Suspended objects, as devices suspended on aircraft, include various pods and auxiliary fuel tanks. With the increasing functionality of aircraft, any suspended object that needs to be jettisoned or is potentially jettisonable (such as auxiliary fuel tanks or pods) must meet the requirements for aircraft-aircraft separation safety before being installed on an aircraft. This means that during the separation process, the suspended object must not collide with the aircraft and must meet minimum distance requirements.

[0003] Current research on the safety of aircraft-projectile separation mainly relies on wind tunnel testing, among which trajectory capture testing, or CTS (Captive Trajectory System) testing, is a relatively effective evaluation method. Trajectory capture testing is based on the coordinated operation of computers, six-degree-of-freedom mechanisms, and wind tunnels. By measuring the aerodynamic load of the launched object, calculating its trajectory, and controlling the six degrees of freedom of the launched object, it simulates the trajectory of the suspended object after it leaves the carrier aircraft.

[0004] Before conducting CTS (Computer-Surrounded Telescope) tests, the pitch, yaw, and roll of the test model need to be calibrated. The attitude adjustment of the suspended structure has a crucial impact on the test results. Because the CTS model is smaller than the carrier aircraft model, it is generally difficult to install measuring equipment on the model for calibration. Currently, common methods include scribing lines during model fabrication or designing a dedicated measuring platform for each model requiring testing. Scribing lines has a larger error margin and is more difficult to measure roll and yaw attitudes. A measuring platform can effectively measure the attitude of the test model, but each different test model uses a different balance with inconsistent cone sleeve dimensions, requiring a dedicated measuring platform to be designed for each model.

[0020] Example 1. A clamping device for a trajectory capture test measurement platform, see [link to example]. Figures 1-3 The system includes a clamping through hole 2 on the measuring platform 1. The front and rear ends of the clamping through hole 2 are provided with clamping grooves 3. The bottom surface of the clamping groove 3 is provided with one or more guide grooves 4 around the opening of the clamping through hole 2. Correspondingly, one or more movable clamping blocks 10 are also provided around the opening of the clamping through hole 2. A turntable 5 is also provided inside the clamping groove 3. Inside the clamping groove 3, the movable clamping blocks 10 and the turntable 5 are stacked sequentially from the inside to the outside along the axial direction. The turntable 5 is provided with one or more driving grooves 6 along the circumferential direction. The inner and outer end faces of the movable clamping blocks 10 are provided with guide posts 7. The guide post 7 located on the inner end face is slidably connected to the corresponding guide groove 4, and the guide post 7 located on the outer end face is slidably connected to the corresponding driving groove 6.

[0021] The outer end face of the aforementioned turntable 5 is provided with a turntable handle 8.

[0022] The aforementioned measuring platform 1 has a positioning hole 9 radially arranged along the clamping through hole 2.

[0023] The top of the aforementioned measurement platform 1 is a T-shaped plane.

[0024] A level is placed on the aforementioned T-shaped plane.

[0025] The aforementioned movable clamping block 10 consists of 10 pieces.

[0026] After installing the rear of the test CTS model 11, insert the model cone sleeve 12 of the test CTS model 11 into the clamping through hole 2, align the positioning hole 9 with the threaded hole of the model cone sleeve 12, and then rotate the turntable 5 at both ends of the clamping through hole 2, which will drive each movable clamping block 10 to gather towards the center of the clamping through hole 2 and clamp the CTS model cone sleeve 12.

[0027] After clamping, the test CTS model 11 and the measuring platform 1 are locked together. The measuring platform 1 and the test CTS model 11 are then secured together using screws or pins through the surrounding positioning holes 9. Afterwards, a measuring instrument (such as a level) can be placed on the T-shaped plane at the top of the measuring platform 1 to check and adjust the model's posture. Once the adjustment is complete, rotating the turntable 5 releases the lock between the measuring platform 1 and the CTS model's conical sleeve 12. This completes the entire measurement process.
