Twin Engine Pack System: A Twin Piston Engine Propulsion Unit For Very Light Rotorcraft

The paper presents the conceptual design of a new class of very light rotorcraft: a twin piston-engine helicopter. Exploiting the Twin Engine Pack System developed by Robby Moto Engineering, a a lo-cost Class-A VTOL aircraft that can potentially fly over densely populated areas can be developed filling a gap in the current rotorcraft market.
