The Mudry CAP 20 is a French family of aerobatic competition single seater monoplanes.
Design and development
[edit]The Mudry CAP 20 was developed at the same time as the CAP 10, as a single-seat aerobatic version. It was followed by a lightweight version designated the CAP 20L which in turn was replaced by the CAP 21 with more advanced wing.
The CAP 20 was developed as a single-seat acrobatic version of the company's CAP 10; it was used by the French Air Force's flying demonstration team, Equipe de Voltige Aerienne. The CAP 20L is externally similar to the 20, but is a structurally new design. The wing planform is more angular; the dihedral is less (1.5 degrees); the fuselage cross-section is distinct, with a rounded top (the 20 used a triangular-shaped top deck). Its dimensions are slightly reduced, and the empty weight was considerably lower (the L stands for leger, or light).
Production of the 20L was suspended in July 1979, when managers decided to improve its wing design. However, when the new wing was introduced, the overall design was tweaked to the point that a new designation (CAP 21) was used to designate the series.
The CAP-21 was then developed as the CAP-230.

[edit]- ^ The prototype, fitted with a 180 hp engine, first flew from Bernay, with Louis Pena at the controls. While completing certification flights at the Centre d'Essais en Vol (Istres), it appeared at the 8th World Aerobatic Championships in Kiev. In mid-October 1976 the airframe was relegated to structural testing at CEAT (Toulouse), and did not fly again.
