Problems solved by technology

[0003] For the smoke detection system test in the construction field, because the configuration characteristics, internal dimensions, internal airflow characteristics, fire characteristics, and smoke detector performance indicators of the building are quite different from those in the aviation field, it is impossible to simulate the interior of the aircraft cabin, especially the flight test. The air flow field, fire status and response process of the smoke detection system under certain conditions, and there is no clear requirement for system response time, so the performance verification problem of the aircraft cabin smoke detection system cannot be solved
For the aviation field, at present, there is no published relevant literature and information that can provide a set of test methods for the performance verification of the aircraft cabin smoke detection system, and can clearly give the test process of the performance test and the selection of the smoke point position

Embodiment Construction

[0019] Method embodiment: build a ground test cabin according to the actual size of the cargo compartment of a certain type of transport aircraft, and arrange six photoelectric smoke detectors on the ceiling of the test cabin according to the actual layout. The schematic diagram is as follows figure 2 shown. The light transmittance index of photoelectric smoke detector is 80% / ft. According to the above selection method of smoke point positions, six smoke point positions are obtained.

[0020] Such as figure 2 It is a top view of the cabin of a transport aircraft, which includes: cabin boundary outline 1, cargo loading area boundary 2 in the cabin, smoke detector 3, connection line 4 between two adjacent smoke detector positions, and two adjacent smoke detectors The midpoint 5 of the line connecting the positions of the detectors, the smoke point 6 (that is, where the smoke generator is arranged), the cargo dummy 7, and the axis of symmetry 8 of the engine room.

Abstract

The invention relates to a smoke detection system testing method used in an aircraft cabin. The invention mainly provides the smoke detection system testing method which can be applied in the aircraft cabin, is safe and reliable and has strong operability and the steps of the method, especially selection and arrangement of the smoke points. The method has the following advantage: the performancesof the smoke detection systems in the cabins can be efficiently verified through the tests in ground laboratories.

Description

technical field [0001] The invention belongs to the field of aviation, and in particular relates to a test method for a smoke detection system used in an aircraft cabin. Background technique [0002] With the continuous development of aviation technology, the requirements for the smoke detection system in the aircraft cabin are getting higher and higher; the smoke detection system in the cabin can only reduce the loss to the greatest extent and ensure the safety of the aircraft only by giving an early warning of the fire. The function of the performance verification test of the engine room smoke detection system is to verify whether the system can send out an alarm signal within the specified system response time. [0003] For the smoke detection system test in the construction field, because the configuration characteristics, internal dimensions, internal airflow characteristics, fire characteristics, and smoke detector performance indicators of the building are quite diffe...
