The Hummel H5 is an American amateur-built aircraft, designed by Morry Hummel and produced by Hummel Aviation. The aircraft is supplied as a kit or plans for amateur construction.[1]
Design and development
The H5 is a development of the Hummel Ultracruiser Plus and has a gross weight that is heavier than the original Hummel Bird.[1][2]
The H5 features a cantilever low-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear, or optionally tricycle landing gear, and a single engine in tractor configuration. The cockpit is 24.5 in (62 cm) wide.[1]
The aircraft is made from sheet aluminum. Its 22.5 ft (6.9 m) (optionally 25 ft (7.6 m)) span wing employs a Harry Ribblett GA30-618 airfoil and has an area of 100 sq ft (9.3 m2). The aircraft's recommended engine power range is 60 to 85 hp (45 to 63 kW) and standard engines used include the 60 to 85 hp (45 to 63 kW) Volkswagen air-cooled engine four-stroke. Construction time from the supplied kit is estimated as 420 hours.[1][2]
Operational history
By December 2011 twelve examples had been completed and flown.[1]
