Convenient pressure measuring device for airplanes

Abstract

Disclosed is a convenient pressure measuring device for airplanes. The convenient pressure measuring device comprises a pressure sensor, a battery arranged around the pressure sensor and a circuit module which combines with the battery to form an annular shape; at least one memory card is detachably connected in the circuit module, the battery supplies power to the pressure sensor, and measurementsignals of the pressure sensor are transmitted to and stored in the memory cards in the circuit module. According to the convenient pressure measuring device for the airplanes, the pressure sensor, apower supply and the memory cards for storing detection data are combined into a structural part running independently, a power supply line and a signal line do not need to be arranged in the bodiesof the test flight airplanes, the limited electric energy on the airplanes does not need to be consumed, and the whole structural part running independently can adhere to each airplane part the pressure of which needs to be measured through an adhesive layer at any time. By adopting the convenient pressure measuring device for the airplanes, the smallest number of test flight airplanes can be utilized to complete a plurality of test flight tasks, and a lot of funds and time can be saved.

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
