begrudgingly had to catch up to) and 200 kg MTOW plus 200 km data-link range with its largest antenna. This secured Schiebel’s first customer, the UAE Ministry of Defence (MoD), which bought 60 S-100s, convincing the Austrian company to embark on constructing its factory in Wiener-Neustadt, where Schiebel continues to produce its S-100s today, along with its S1 and S2 Wankel rotary engines, its composite material parts, and more. Anatomy The S-100 broadly follows traditional helicopter design. Its engine and management systems sit near the front, driving the main and tail rotors via either one’s gearbox, which are installed at the centre and tail, respectively. The engine’s cooling radiator is installed atop (and aerodynamically conformal with) the nose, while the main fuel tank sits centrally, rearward and lower down than the main rotor gearbox. That fuel tank is a carbon monocoque design and also functions as a structural component of the helicopter fuselage, a patented innovation by Schiebel, aimed at improving strength-to-weight ratio. On top of this, it sits at the approximate centre of gravity (CoG); hence, the CoG remains immobile throughout flight as fuel burns. “Looking closer, there is also a freewheel assembly between the engine and main gearbox, which gives us our autorotation capability,” Hecht says. “A carbon-fibre driveshaft from the main gearbox runs into and drives the tail gearbox, the latter being a very standard, 90° conversion design. All the prop blades are Schiebel-designed as there’s never really been COTS or standard blades for a helicopter this size.” A main payload gimbal with up to 50 kg capacity is typically installed at the undercarriage below the main gearbox, with additional payload integration space available in the nose, inside the tail and off the sides in the case of some systems such as synthetic aperture radar (SAR). Hecht notes that the tail section is especially empty as standard, and Better. Faster. More Reliable.
