The invention discloses an ignition test device for a multi-oil-way igniter of an aero-engine, which controls the fuel oil mixing ratio by controlling the flow of each fuel oil output by a multi-oil-way oil supply system, and can realize that the multi-oil-way oil supply system outputs any one of single-component fuel oil, double-component fuel oil and multi-component fuel oil to the igniter. According to the fuel oil ignition test device, ignition tests of single fuel oil, double-component fuel oil and even multi-component fuel oil can be simulated, when ignition performance tests need to be carried out on different fuel oil igniters, manual replacement of the fuel oil is not needed, the efficiency of the ignition tests is greatly improved, the proportion of mixed fuel oil can be adjusted according to actual needs, and adjustment is very convenient. Besides, low-temperature air cooled by the refrigerating system can be provided for the igniter for ignition test on one hand, and can also be used for cooling fuel oil provided by the multi-oil-way oil supply system on the other hand, a fuel oil cooling system does not need to be independently arranged, and the system structure is simplified.
本发明公开了一种航空发动机多油路点火器点火试验装置,其通过控制多油路供油系统输出每种燃油的流量来控制燃油混合比例,可以实现多油路供油系统输出单组分燃油、双组分燃油和多组分燃油中的任一种至点火器,可以模拟单一燃油、双组分燃油甚至多组分燃油的点火试验,当需对不同燃油点火器进行点火性能测试时,无需对燃油进行人工更换,极大地提高了点火试验的效率,并且可以根据实际需要调整混合燃油的比例,调节十分方便。另外,制冷系统降温后的低温空气,一方面可以提供给点火器进行点火试验,另一方面还可以对多油路供油系统提供的燃油进行冷却,无需再单独设置燃油冷却系统,简化了系统结构。
