Design and development

The SparrowHawk was designed to fit into the US FAR 103 Ultralight Vehicles category, including that category's requirement that unpowered aircraft have a maximum empty weight of 155 lb (70 kg). The sailplane achieves this by utilizing a structure that is predominantly made from carbon-fiber-reinforced polymer. [1] [4]

The SparrowHawk's multi-tapered, 36.1 ft (11.0 m) span wing employs five different airfoils and has an aspect ratio of 18.6:1. The wing features Schempp-Hirth style spoilers on the top surface. The cockpit can accommodate pilots who range in height from 63 to 75 in (160 to 191 cm). The landing gear is a fixed monowheel gear with an auxiliary tail wheel. The glider is finished with a two part polyurethane paint. The aircraft can be launched by auto-tow, winch-launch, or aero-tow by both light aircraft and ultralight aircraft. Aerobatics are not recommended. [1] [4]

The SparrowHawk achieves a best glide ratio of 36:1 and a minimum sink rate of 119 ft/min (0.60 m/s). [5]

Fauvel AV.36 Single-seat French glider, 1951

The Fauvel AV.36 was a single-seat tailless glider designed in France in the 1950s by Charles Fauvel. Although the "AV" in AV.36 stands for Aile Volante, it was not a true flying wing: it featured two large fins mounted on stubby tailbooms extending back from the wing's trailing edge, and accommodated the pilot within a stubby fuselage. The aircraft was designed to be quickly disassembled for road transport, with the nose detaching, and the fins able to fold back against the trailing edge of the wing. A refined version with a slightly longer wingspan, the AV.361 was introduced in 1960.

The Slingsby T.49 Capstan is a British two-seat glider of the 1960s built by Slingsby Sailplanes as a replacement for their earlier Type 42 Eagle. It is a high-winged monoplane of wooden construction, the last two-seat wooden glider built by Slingsby, intended for both training and general club flying. Side-by-side seats for the two pilots are accommodated in an enclosed cockpit with a one-piece perspex canopy. The prototype T.49A first flew in 1961, and it entered production as the T.49B in 1963. Thirty-four Capstans were built, one of which was fitted with an auxiliary engine with the designation T.49C Powered Capstan.
