The Chasle YC-100 Hirondelle ({{lang|en|Swallow}}) is a French single seat microlight designed in the 1980s. Design and developmentYves 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 {{convert|20|kW|hp|abbr=on|0}}, 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 {{convert|18|kW|hp|abbr=on|0}} König SC 430 engine, a 430 cc (26.2 cu in), air-cooled, three-cylinder radial. The second prototype, built in Brazil, had a {{convert|22|hp|kW|abbr=on|order=flip|0}} JPX PUL 425/503 engine, a 212 cc (12.9 cu in) air-cooled flat-twin two stroke.[[3]] The number built is uncertain; in 2009 two examples, both YC-100s, appeared on European civil registers, one in Spain and one in France.[4] VariantsPlans 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 {{convert|22|hp|kW|abbr=on|order=flip|0}} JPX PUL 425/503.
- YC-101
- As YC-100 but span increased to {{convert|9.35|m|ftin|abbr=on|0}}. Recommended engines were the JPX PUL 865, the {{convert|28|hp|kW|abbr=on|order=flip|0}} König SD 570 or the {{convert|30|hp|kW|abbr=on|order=flip|0}} KFM 107ER.
- YC-110
- Shorter span ({{convert|8.25|m|ftin|abbr=on|0}} 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 ({{convert|9.35|m|ftin|abbr=on|0}}) YC-110. Recommended engines were the König SD 570, KFM 107ER, JPX PUL 865 and also the Rotax 377 or 447, respectively {{convert|26|kW|hp|abbr=on|0}} and {{convert|29.4|kW|hp|abbr=on|1}}.
