- Apache Helicopter Turbine Powerplant -
Engine and Main Gearboxes
Several years ago, EPI designed a powerplant system for a kit-built helicopter in the experimantal aircraft market. The system used the 150-hp T-62 turbine engine and provided reliable drive systems, with unloading and autorotation clutches, for the main rotor system and tail rotor system.
As a result of a business decision to withdraw from experimental aviation environment, with all its liability exposure, controversy, acrimony and wishful-thinking-engineering, EPI shelved the design before the prototype was completed.
Recently, a new helicopter company contracted with EPI, Inc. to revise and adapt this system to power the new helicopter they have in development.
