Embodiment Construction

[0016] Attached below figure 1 The present invention will be described in detail.

[0017] The compression switch is installed inside the test aircraft, and the other side of the compression switch is pressed by a compression switch fixing component. Usually, the compression switch is in a closed state due to the compression force. When the test aircraft and the carrier aircraft When separating, the compression switch fixing component releases the compression force under the action of external force, the compression switch changes from the compression state to the loose state, and the other three compression switches are released at the same time for detection by the detection system.

[0018] The highly reliable separation state detection method provided by the present invention includes the signal detection of the pressing switch and the signal detection of the short jump wire of the separation plug. The detection is carried out in parallel by two methods. Under normal work...

Abstract

The invention discloses a high-reliability separation state detection method. The method comprises the following steps that: step one, a detection circuit is arranged, a first group of compression switches 1 and 2 are connected in parallel and a second group of compression switches 3 and 4 are connected in parallel, the two groups of compression switches are connected in series, an add-drop short overline 1 and an add-drop short overline 2 are connected with the two groups of compression switches in parallel to form fourth paths of circuits, and the detection system is connected with common ends of the four paths of circuits to form a closed loop; step two, the detection system receives a separation instruction signal that indicates separation of an aircraft and an aerial carrier and is sent out by a ground control system and collects on-off information of the detection circuit; step three, the detection system receives signals from the four paths of circuits; and step four, the detection system carries out processing on the four-path signals received at the step three. According to the invention, only compression switches, compression switch fixing assemblies, separation plugs, and add-drop wires are used for state detection and the traditional separation mechanism including a gas circuit disconnection device and a fluid path disconnection device is replaced, thereby lowering the cost.

Description

technical field [0001] The invention relates to a separation state detection method, which belongs to the field of test aircraft. Background technique [0002] With the development of aircraft, aircraft with various aerodynamic layouts and new concept aircraft are emerging. In order to verify the performance of the aircraft, it is necessary to take the flight test of the aircraft mounted on the aircraft. Various foreign aircraft such as X-51A, X- The 37B has also carried out similar flight tests. In the launch flight test, the detection of the separation status signal is very critical. When the aircraft detects the separation signal, it will start autonomous control. If the aircraft has separated from the carrier aircraft but has not received the separation signal, the aircraft will not start the autonomous control, causing the test to fail. , so state detection is a key signal, and the reliability of its detection is very high. [0003] For the reliable detection of the s...
