According to the flight test requirements, it is necessary to employ the photogrammetry method in the bomb cabin. The high-speed camera should be installed at the appropriate position within the bomb cabin for binocular stereoscopic rendezvous measurement. This will enable testing of weapon projection at different altitudes of the aircraft and facilitate detection of separation process, speed, and...Show More
In the face of the test environment and requirement change on the plane, laboratory testing calibration method of the force parameter has been unable to meet the requirement of the present. According to the principle of force sensor, developed a new test method that can realize field calibration of the airplane stick (helm) force parameters. This article firstly has carried on the demand analysis ...Show More
The opening angle of the aircraft hatch door is crucial for ensuring weapon delivery safety and serves as a necessary test subject in flight testing. Currently, the angle measurement of the hatch door can only determine its open or closed state without providing quantitative measurements. The traditional method of measuring the control mechanism's angle in flight tests involves installing a contac...Show More
This paper introduces a novel type of optical fiber grating capable of simultaneous temperature and strain measurement. The grating is fabricated using the ultraviolet lithography method, involving the removal of photosensitivity from a small section of the fiber prior to writing the grating using electrode discharge. The phase shift grating formed by this method is used as an optical fiber sensor...Show More
This paper proposes a low-light image enhancement technology for complex optical environments, which improves imaging quality in low-light conditions through three main designs: strong light suppression, image enhancement processing, and infrared supplementary lighting. These techniques achieve night vision image enhancement and restoration, maximizing the reproduction of the target object, and im...Show More
In order to promote the application of fiber Bragg grating (FBG) sensor in strain measurement of flight test field, ground verification tests were carried out, and the effects of the packaging structure and the bonding technology of the sensor were analyzed. FBG has the advantages of small size and light weight in flight test applications, but the optical fiber is easily damaged, so it is necessar...Show More
In flight test, the aircraft will produce mixed combustible gas, and the change of gas concentration will bring great security risks to flight test safety. In view of the limitations of traditional test methods, such as long response time and low accuracy, the new aircraft and new mission put forward higher requirements for gas concentration test. According to the requirements of the model task, t...Show More
Flight test puts forward higher requirements for air data test. Aiming at the limitations of traditional test methods, a new airborne optical air data system is developed to realize high-precision non-contact airspeed measurement. This paper mainly expounds the system composition and function module design scheme, introduces the laser Doppler velocity measurement principle and vacuum velocity vect...Show More
