SMA develops and manufactures piston engines burning Jet fuels, purposely-designed for the general aviation market, for single and multi-engine aircraft.
SMA is currently making production of the SR305-230E, its 4-cylinder engine of 230 hp. A new 6-cylinder engine is under development with power over 300 hp.
SMA engines technology emphasizes reliability and robustness, with the same ease of operation as with turboprop models.
SMA has developed and tested on a demonstrator, a concept of High Power Density Engine (HPDE), rivaling the turbines power density.
With a weight of 240kg (529 lbs) as installed, this engine is designed to deliver up to 800 HP.
It is a new world class Jet A piston engine leader in power density, and an ideal solution for the power generation and hybrid propulsion for future small and mid-size commuter-aircraft, rotorcraft and drones.
Based upon state-of-the-art compression engine technologies, the HPDE offers reliability, low cost of operation, long range and endurance, as a stand-alone solution or in combination with turbines.
