Our engine test bench, WF-EN-55, can test the engine from 110~550cc, max propeller 60in and engine weight max is 35kg.
We have our UPS power supply for the bench. You can control your engine on our bench so as to test thrust, torque, optical rpm, pulse rpm, cylinder temperature and exhaust temperature. We also offer the spare interface for clients to add their own sensors. The UAV engine test bench is also included the environmental module for testing.
About Limbach L550E, a lightweight four-stroke aircraft engine, designed for UAVs and light aircraft. It can be also tested on our engine test bench. Our clients are in the world, including many famous companies. You can test the power, fuel flow and fuel pressure as well. We can custom the cooling system for our clients as you want.
Here are our specification of WF-EN-55 engine test bench:
