Aircraft convenient pressure measuring device

Abstract

The invention relates to a convenient pressure gauge of an airplane. The pressure gauge comprises a pressure sensor, a battery surrounding the pressure sensor and a circuit module, the circuit module and the battery are combined to form an annular unit, the circuit module is detachably connected with at least one memory card, the battery supplies to the pressure sensor, and the pressure sensor transmits measuring signals to the memory card and stores the measuring signals in the memory card. According to the convenient pressure gauge of the airplane, the pressure sensor, the power supply and the memory card for storing detection data are combined to form a structural part which operates independently, it is not required to lay power lines and signals lines in an trial airplane body, limited electric energy of the airplane is not consumed, and the structural part which operates independently can be pasted to an airplane part whose pressure needs to be measured at any time. The convenient pressure gauge of the airplane can be used to complete different trial flight tasks with minimal trial airplanes, and can save a lot of money and time.

Description

technical field [0001] The invention relates to an aviation aerodynamic testing device, in particular to a convenient pressure measuring device used for testing the pressure of the structural components of the aircraft during the flight test of the aircraft. Background technique [0002] After a new type of aircraft is designed and produced, it needs to be tested to test whether the overall power, operability and safety of the entire aircraft from take-off to various actions in the air to landing are feasible, and whether they are in line with the original design. , so as to fully demonstrate the overall performance of the aircraft. New aircraft generally have to go through dozens or even hundreds of test flights before they can be finalized. [0003] Before a new type of aircraft is finalized, several aircraft are usually assembled for test flight. During the assembly process of these aircraft, according to the requirements of the test flight mission, they will be assembled...

AI Technical Summary

Problems solved by technology

[0004] Usually, a certain flight test aircraft can only be used to undertake part of the flight test tasks. This is because the structure of the aircraft is complex and the space is small. A large number of sensors need to be installed on the aircraft to arrange a large number of power lines and signal lines, which consumes the limited power on the aircraft. There is no way to install all the sensors on all the structural components that need to be inspected at one time. Therefore, before the aircraft is finalized, it is often necessary to have multiple flight test aircraft for different test flight tasks, which requires an astonishing amount of money

After the flight test aircraft has installed the sensors and finally assembled the skin and other structural components, it is basically difficult for these sensors to be replaced, repaired, or even rearranged. , once the test flight mission is completed, or the pre-installed pressure sensor gradually fails during the test flight, the test flight aircraft can basically only be scrapped, wasting a huge amount of money

When the flight test project cannot be completed due to the failure of the sensor, it is necessary to reassemble a new test flight aircraft for test flight, which greatly delays the flight test process and has a serious adverse effect on the finalization of the aircraft
