Schiebel recently conducted the successful first flight of a heavy-fuel-powered CAMCOPTER® S-100 UAS (Unmanned Air System). After extensive development, the S-100 successfully made its maiden flight with a new heavy fuel engine at Schiebel’s range near the production facility in Wiener Neustadt, Austria. The Schiebel-designed engine fulfilled all expectations and series deliveries are scheduled to begin in the fourth quarter of 2012.

The heavy fuel engine developed by Schiebel gives operators the ability to use JP-5 (F-44), Jet A-1 (F-35), and JP-8 (F-34). This is a flexibility that is not available in other tactical VTOL UAS. The current basic power plant of the CAMCOPTER® S- 100 is a Wankel-type (rotary piston) engine, which runs on 100 octane-grade avgas (aviation gasoline) and is rated at 50 HP. Recent engineering developments have led to the gasoline version of the engine being certified to operate on 95 octane lead-free petrol without loss of power.

The new heavy fuel engine is fully interchangeable with the current engine, and upgrades can be made by just replacing the core engine with some accessories of similar specifications and flight performance. In offering lower logistic effort and supporting the single-fuel concept that requires using only one fuel while deployed, this new engine is suitable for maritime applications. The added flexibility this new engine provides should increase the types of missions that can be undertaken by the unmanned helicopter.
