The Chasle YC-100 Hirondelle (Шаблон:Lang) is a French single seat microlight designed in the 1980s.

Design and development

Yves Chasle worked as an Aérospatiale stress engineer and independently designed several light aircraft, starting with the Chasle YC-12 Tourbillon. His YC-100 Hirondelle is a largely wooden framed and fabric covered single-seat sports aircraft of conventional pusher layout. It has a strut braced high wing of constant chord with styrofoam ribs. The fuselage of the Hirondelle is a slender, rectangular cross-sectioned beam with the pilot's seat upon it ahead of the wing leading edge. Behind the pilot a central structure supports the wing just above head level; on its trailing edge, one of several types of small piston engine, with power outputs typically around Шаблон:Convert, drives a pusher propeller. The fin is broad and straight-tapered and the horizontal tail is attached to the fuselage underside. The Hirondelle has a short, fixed tricycle undercarriage.

Its first flight was on 1 May 1985, powered by a Шаблон:Convert König SC 430 engine, a 430 cc (26.2 cu in), air-cooled, three-cylinder radial. The second prototype, built in Brazil, had a Шаблон:Convert JPX PUL 425/503 engine, a 212 cc (12.9 cu in) air-cooled flat-twin two stroke.

The number built is uncertain; in 2009 two examples, both YC-100s, appeared on European civil registers, one in Spain and one in France.

Variants

Plans for these were available but only the YC-100 is known to have been built.

YC-100

As described below but could also be fitted with a Шаблон:Convert JPX PUL 425/503.

YC-101

As YC-100 but span increased to Шаблон:Convert. Recommended engines were the JPX PUL 865, the Шаблон:Convert König SD 570 or the Шаблон:Convert KFM 107ER.

YC-110

Shorter span (Шаблон:Convert wings with NACA 23015 section and Junkers type, two part, full span auxiliary airfoil ailerons or flaperons. Recommended engines as YC-100 and also the König SD 570.

YC-111

Longer span (Шаблон:Convert) YC-110. Recommended engines were the König SD 570, KFM 107ER, JPX PUL 865 and also the Rotax 377 or 447, respectively Шаблон:Convert and Шаблон:Convert.
