With the increasing maturity of aviation technology, greater attention is being paid to the flammability testing of aviation materials. Internationally used aviation fuel burners are also being more widely adopted for testing a variety of materials used in aerospace vehicles.

 

This aircraft material flame combustion tester is designed and developed according to relevant international and domestic standards, using a large imported American gas burner and corresponding standard-based design principles. It is increasingly adopted by authoritative aviation research institutes in China.

 

The equipment is a multifunctional combined test bench. It can perform combustion tests using both a large combustible gas burner and a small gas burner on onboard equipment, accessories, and structural parts in designated aircraft fire zones, including cables, electrical connectors, hoses, and pneumatic components.

 

The latest second-generation burner from TESTech is newly designed according to the latest FAA requirements. It addresses the discontinuation of the first-generation prototype burner and the instability in temperature and heat output of the first-generation design. This burner fully satisfies relevant FAA requirements for fire testing of different aircraft materials.
