Aircraft engine compartment fire experiment equipment

Abstract

The invention discloses a piece of aircraft engine compartment fire experiment equipment which can be used to carry out an experiment for engine compartment fire dynamics research and carry out experimental verification of an aircraft fire prevention system. The equipment comprises an air inlet, a compartment body, an air outlet, an observation window, fake engine parts, a heating component, an engine compartment congestion part simulation device, a fire extinguishing agent concentration test interface, an oil pool fire module, a spray fire simulator interface, a temperature measurement module, an airflow velocity measurement module, a pressure measurement module, a laser flow field measurement module and a compartment body bracket. Compared with the prior art, the aircraft engine compartment fire experiment equipment can be used to carry out an experiment for aircraft engine compartment fire dynamics research and simulate the influence of the engine surface temperature on the experimental boundary conditions in the compartment.

Description

technical field [0001] The invention relates to the technical field of test and verification of an aircraft fire protection system, in particular to an aircraft engine compartment fire test equipment. Background technique [0002] With the continuous development of the aviation industry and the advancement of science and technology, more and more attention has been paid to the safety of aircraft, especially the safety and airworthiness of aircraft are very important. Aircraft engine compartment fire protection is an important part of the aircraft fire protection system, and the scientific research and effectiveness of the aircraft engine compartment fire protection system need to be verified through experiments. [0003] Existing aircraft engine compartment fire protection system experimental equipment, such as the test cabin described in the Chinese patent "A Fire Extinguishing Test Assembly for Aircraft Engines" (CN105865797A), can only carry out the test of fire extinguis...
