Evaporative load tank for aircraft testing

Abstract

The invention belongs to the technical field of aircraft flight testing, and particularly relates to an evaporative load tank for aircraft testing. The aircraft power is extracted by heating evaporative liquid, so that safe storage and discharging of the evaporative liquid. At the present, in a testing stage, a load for extracting the aircraft power on an aircraft mostly adopts an air cooling type electric load mode, and the other way is to install an electric load in an engine room, but heat generated by the electric load cannot be dissipated, and the noise severely affects normal work of flight-test personnel. The evaporative load tank adopts a boiler pressure container; single load units are annularly distributed at the circumference of a tank body in a multi-layer manner so as to extract the electric power of the aircraft and realize load consumption; superfine glass cotton is adopted for heat isolation protection, so that safe storage of the evaporative liquid is realized, and the test personnel can be prevented from being scalded; by the arrangement of an anti-spilling isolation net and a top special connection opening, no liquid is spilled from the tank in the flight-test process; and pressure and temperature sensors are arranged at the top for real-time monitoring, and under conditions of over pressure and over temperature, work of a system is interrupted, and the safety of flight test of the aircraft is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of aviation flight test, and in particular relates to an evaporative load tank used for aircraft test, which extracts aircraft power by heating evaporating liquid, and realizes safe storage and discharge of evaporating liquid. Background technique [0002] At present, in the test stage, the loads that extract the power of the aircraft on the aircraft mostly adopt the air-cooled electric load method. The electric load method must adopt air blowing to dissipate heat. Generally, the pod is hung outside the aircraft fuselage to dissipate heat through atmospheric convection during flight; An electric load is installed in the cabin, but the heat generated by it cannot be dissipated, and the noise seriously affects the normal work of the flight test personnel, so other methods of extracting aircraft power are needed. Contents of the invention [0003] The evaporative load tank is installed on the test aircraft, a...
