Design and development

The Pouchelec is a development of the APEV Pouchel Light, adapted for electric power, including revised landing gear and longer span wings with greater surface area. The original Pouchel was constructed using three commercially available aluminium ladders, hence APEV is the Association pour la Promotion des Echelles Volantes, or in English, Association for the Promotion of Flying Ladders. Later models were forced to move to rectangular aluminium tubing when the ladder manufacturer grew concerned about liability. The Pouchel series are all derivatives of the classic 1930s Henri Mignet-designed Mignet Pou-du-Ciel (Flying Flea).[2][3][4]

The Pouchelec features a cantilever rear wing with a strut-braced parasol front wing, a single-seat open cockpit without a windshield, fixed conventional landing gear and a single engine in tractor configuration. The aircraft is made from bolted-together aluminium tubing, with its flying surfaces covered in Dacron sailcloth. Its 7.30 m (24.0 ft) span front wing and 5.30 m (17.4 ft) span rear have a combined area of 14.6 m2 (157 sq ft) and both employ NACA 23112 airfoils. The engine supplied is a 15 kW (20 hp) AGNI 119R electric motor powered by a Kokam Lithium-ion polymer battery pack, which gives a 30-minute flight endurance.[2][3][4]

As of late 2017 it was no longer listed as available as plans or a kit.[1]

Operational history

Bayerl et al. describe the aircraft in flight as "wonderfully quiet".[2]
