Description

Technical Field

[0001] The present invention relates to the field of optoelectronic technologies, and particularly to an installation attitude adjustment mechanism for an optoelectronic pod. Background Art

[0002] An optoelectronic pod is an important component in optoelectronic reconnaissance and detection equipment. Generally, it is installed on a carrier and moves with the carrier. By controlling the rotation of the optoelectronic pod, the orientation of the optoelectronic equipment inside the pod can be controlled, thereby realizing the reconnaissance and detection of target objects. As a carrier for loading optoelectronic detection equipment, the centroid position of the pod relative to the carrier has a great impact on the reconnaissance and detection data and imaging quality of the pod. Optoelectronic pods are generally used for airborne applications. As equipment for the aircraft to detect and reconnoiter externally, the pod transmits the detected data information back to the aircraft for use. The accuracy of the transmitted data information is extremely important. In addition to the detection accuracy of the optoelectronic equipment inside the pod, the centroid position of the pod itself relative to the aircraft is also extremely important. Moreover, as an aircraft moving at high speed, the centroid position of the pod relative to the aircraft is constantly affected by interference and changes.

[0003] Since the pod is not installed at the preset centroid position, it affects the imaging and data validity of the pod. Or during the high-speed movement of the aircraft, the centroid position of the pod deviates due to external interference factors, which also affects the imaging and data validity of the pod. The non-coincidence of the centroid position of the optoelectronic pod and the preset centroid position of the aircraft is called the centroid position deviation of the optoelectronic pod. Due to the centroid position deviation, the optical axis center of the optoelectronic equipment inside the optoelectronic pod and the center of other airborne equipment on the aircraft cannot coincide, resulting in a significant reduction in the data validity of the optoelectronic pod. At the same time, due to the displacement superposition caused by the high-frequency vibration excitation generated by the aircraft itself on the optoelectronic pod, the imaging of the pod itself becomes worse, seriously affecting the imaging quality of the pod.

[0004] The traditional installation attitude adjustment method of the optoelectronic pod is operated through an adapter plate at the interface. To achieve the coincidence of the centroid position of the pod and the preset position of the aircraft in three axial directions, an installation plate with adjustable holes must be used. When statically installed, by continuously adjusting the position of the installation holes and conducting multiple tests to confirm the coincidence of the centers in the X-axis and Y-axis directions with the preset center, and for the coincidence in the Z-axis direction, it is necessary to confirm the coincidence of the preset center in the Z-axis direction of the pod by increasing or decreasing the thickness or installation height of the adapter plate, so as to ensure that the centroid position of the optoelectronic pod is consistent with the preset position. This traditional installation adjustment method can well adjust the correct attitude during static installation. However, when the fuselage is in dynamic use, at this time, due to vibration excitation, the installation position will shift. During actual use, it is always impossible to ensure the real-time correctness of the pod attitude, and a cumbersome adjustment process needs to be repeated, resulting in low adjustment efficiency.
