The Arup S-2 was the first commercial development of Cloyd Snyder's Arup S-1 low aspect ratio wing aircraft.
Recognition (WEFT)
| W — Wings | Mid-mounted, tapered |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 5.18 m fuselage |
| T — Tail | No tailplane |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Guitar-pick planform: straight leading edge with a trailing edge tapering to the rear
- Large trailing-edge control surfaces mixed for pitch and roll
- Small movable semi-circular wingtips for extra roll control
Conventional landing gear was faired with wheel pants, and the cockpit was entered through a belly-mounted hatch with celluloid panels in the belly for visibility.
Specifications
- The Arup S-2 has a length of 5.18 m (17 ft).
- It has a wingspan of 5.79 m (19 ft).
- Its maximum speed is 156 km/h (97 mph).
Figures are for the representative variant described above; marks differ. See how AircraftIQ sources figures.
History
It was designed by Raoul Hoffman and built by the Arup Manufacturing Corporation, first flying in April 1933. An M6 airfoil was chosen over the S-1's sharp-edged, modified Clark-Y section.
Variants
Only one S-2 was built. It was developed from the Arup S-1 and led to the Arup S-3.
Where you'll see it
Powered by a 36 hp Continental A-40, it had a stall speed of 23 mph.
