ICA IS-29

The ICA IS-29 was a sailplane built in Romania in the 1970s. The prefix IS comes from Iosif Șilimon, the Romanian IAR (Industria Aeronautică Română) aeronautical engineer who designed it.

Design and development

The 15-metre (49ft 3in) single-seat variant of the IS-28 series, the IS-29D2 single-seater has retractable gear, camber-changing flaps and Hütter-type airbrakes on the upper wing surface only. The T-tail has a fixed stabilizer and elevator. The –29D model is of all-metal construction while the earlier –29B has wooden wings. Developments include 19 metre (62 ft) -29E2 and 20 metre (66 ft) -29E3 versions and a flapless, fixed gear 16.5-metre (54 feet) ‘club’ model -29G.

The IS-29 was also produced in a motorglider version, designated the IS-29EM. This shared the low-set wings and three-point undercarriage of the IS-28M2, and the new wings of the IS-28MA.
