Abstract

The invention discloses airport pavement temperature testing equipment and a testing method for the aircraft wake flow, and relates to the field of airport engineering construction and airport wake flow temperature testing. According to the invention, the problem that the judgment of the temperature result of the airfield pavement is affected due to large errors caused by the problems of test distance, angle and the like in the conventional measurement mode by adopting fixed or movable thermal infrared imagers fixed on the two sides of the runway shoulder is solved. A first temperature sensing element is embedded in the edge of a top cover of a lamp to obtain the temperature of the wake flow of the airplane, and the upper ends of a second temperature sensing element and a third temperature sensing element are inserted into a reserved mounting through hole and a reserved mounting blind hole of the top cover of the lamp respectively. The second temperature sensing element obtains the temperature of the airport pavement surface and the temperature of the lamp top cover under the action of the external environment containing the aircraft wake flow, and the third temperature sensing element obtains the temperature of the lamp top cover. The equipment and the method are used for accurately obtaining the temperature field influence of the high-temperature wake flow of the aircraft engine exhaust nozzle on the airfield pavement, so that the airfield pavement use performance can be estimated in real time.

Description

technical field [0001] The invention relates to the fields of airport engineering construction and aircraft wake temperature testing, in particular to an airport pavement temperature testing device and a testing method for aircraft wakes. Background technique [0002] With the development of society and economy and the improvement of people's living standards, air transport has gradually become a popular travel choice due to its advantages such as comfortable and convenient boarding environment, increasingly low air ticket prices, and transport efficiency that other modes of transport cannot match. Airport construction continues to develop rapidly. According to statistics released by the National Data Network, there will be 240 civil airports in my country in 2020, with an annual passenger throughput of 857 million passengers. There are as many as 39 civil airports with a middle-year passenger throughput of more than 10 million passengers. Facing the sharp increase in traff...
