Endurance Testing Success for Suter’s TOA288 Engine
The Suter TOA288 engine has successfully completed an endurance test in compliance with the Federal Aviation Governance (FAA) regulation section 33.49, wich governs reciprocating engines. This rigorous testing standard is essential for certifying piston engines used in manned aircraft and is frequently applied to evaluate engines in unmanned aerial vehicles (UAVs).
Engine Specifications and Design Collaboration
Featuring a twin-cylinder, horizontally opposed configuration, the Suter TOA288 is an air-cooled, two-cycle engine that employs fuel injection technology alongside a sophisticated electronic engine management system and a 1kW starter/generator.With a displacement of 288 cm³,it delivers a power output of 17.5 kW (24 HP) at 6500 RPM. this engine is the result of a collaborative design effort between CAE GmbH and Suter industries, merging CAE’s extensive 25-year expertise in both manned and unmanned two-stroke engines with Suter’s rich history in two-stroke motorcycle racing design and manufacturing.
Durability testing and Performance Evaluation
Currently powering various UAV platforms worldwide,the 24 HP engine underwent rigorous testing at Suter’s facility in Turbenthal,Switzerland,to assess its durability. Following a thorough 150-hour FAR 33.49 endurance test, performance evaluations and component inspections revealed no signs of performance degradation or accelerated wear. The engine has been reassembled with its original components and is set for further testing.
Future Implications and Industry Impact
The findings from these tests will be instrumental for Suter in establishing the Time Before Overhaul (TBO) and maintenance schedules, ensuring the engine’s reliability and competitive operational costs over its lifespan. This strategic approach aims to enhance the engine’s market viability and operational efficiency.
Upcoming Showcase at AUVSI’s Xponential Conference
Suter’s TOA288 engine will be prominently featured at the AUVSI’s Xponential conference in Atlanta, presented by UAV Propulsion Tech, highlighting its innovative design and robust performance capabilities.
