The Windward Performance SparrowHawk is an American mid-wing, single-seat glider that was designed and produced by Windward Performance. [1] It first flew in 2002. [2]
Since 2016 the aircraft has been no longer advertised as available by the manufacturer. [3]
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]
