Oshkosh / Wisconsin, U.S.A., July 21, 2015 – BRP introduces a more powerful 135-hp Rotax aircraft engine at the EAA AirVenture in Oshkosh, Wisconsin – the Rotax 915 iS.
Based on the proven concept of the Rotax 912 / 914 engine series, the Rotax 915 iS engine offers more power, the best power-to-weight ratio in its class and full take-off power up to at least 15,000 feet (4,570 m) with a service ceiling of 23,000 feet (7,010 m).
“This more powerful aircraft engine – the Rotax 915 iS – was specifically requested by our customers. It opens the market to larger, heavier aircraft, larger gyrocopters and even small helicopters, or simply more performance for current applications,” said Thomas Uhr, vice president BRP-Powertrain and general manager BRP-Powertrain GmbH & Co KG. “BRP’s Rotax 4-stroke aircraft engines are already industry leaders; opening other markets represents a good growth opportunity.”
The introduction of the Rotax 915 iS engine, a 4-stroke, 4-cylinder turbocharged aircraft engine with intercooler and a redundant fuel injection system, is in response to market demand for a modern, more powerful engine allowing higher payload and shorter take-offs. It delivers the most advanced aircraft engine technology resulting in low operating cost and ease of use. The serial production of the Rotax 915 iS engine is scheduled for second half of 2017.
