[edit] Design and development

In the late 1950s, the Soviet Air Force was seeking a jet-powered replacement for its fleet of piston-engined trainers, and this requirement was soon broadened to finding a trainer aircraft that could be adopted in common by Eastern Bloc air forces. Aero's response, the prototype XL-29 designed by Z. Rublič and K. Tomáš first flew on 5 April 1959, powered by a British Bristol Siddeley Viper engine. The second prototype was powered by the Czech-designed M701 engine, which was used in all subsequent aircraft.

The basic design concept was to produce a straightfoward, easy-to-build and operate aircraft. Simplicity and ruggedness were stressed with manual flight controls, large [[Flap (aircraft}|flaps]] and the incorporation of perforated airbrakes on the fuselage sides providing stable and docile flight characteristics, leading to an enviable safety record for the type. The sturdy L-29 was able to operate from grass, sand or unprepared fields. Both student pilot and instructor had ejection seats, and were positioned in tandem, under separate canopies with a slightly raised instructor position.

In 1961, the L-29 was evaluated against the PZL TS-11 Iskra and Yakovlev Yak-30 and emerged the winner. Poland chose to pursue the development of the TS-11 Iskra anyway, but all other Warsaw Pact countries adopted the Delfin.

Production began April 1963 and continued for 11 years, with 3,500 eventually built. A dedicated, single-seat, aerobatic version was developed as the L-29A Akrobat. A reconnaissance version with nose-mounted cameras was built as the L-29R.

[edit] Operational history

The Delfin served in basic, intermediate and weapons training roles. For this latter mission, they were equipped with hardpoints to carry gunpods, bombs or rockets, and thus armed, Egyptian L-29s were sent into combat against Israeli tanks during the Yom Kippur War. The L-29 was supplanted in the inventory of many of its operators by the Aero L-39 Albatros. More than 2,000 L-29s were supplied to the Soviet Air Force, aacquiring the NATO reporting name "Maya."

As a trainer, the L-29 enabled air forces to adopt an "all-through" training on jet aircraft, replacing earlier piston-engined types.

On October 2, 2007, a modified L-29 was used for the world’s first jet flight powered solely by 100% biodiesel fuel. Pilots Douglas Rodante and Carol Sugars flew their Delphin Jet at Stead Airport, Reno, Nevada in order to promote environmentally friendly fuels in avaiation.

Aero L-29 Delfín


History: The prototype of the L-29 Delfin ("Dolphin") trainer, called the XL-29, first flew in Czechoslovakia on 5 April 1959, powered by a Bristol Siddeley Viper turbojet engine. The second prototype, first flown in July 1960, was powered by the Czech-designed M701 engine, which was to become the standard installation.

In 1961, the L-29 was entered in a competitive design evaluation to find a new Warsaw pact basic/advanced jet trainer to replace the piston-engine trainer fleet. The other competitors were the Russian Yakovlev Yak-30 and the Polish TS-11 ISKRA. The L-29 won and subsequently became the standard trainer in all Eastern-bloc counties except Poland.

The first production Delfin rolled off the assembly line in April 1963, and production continued for more than 11 years, a huge statement of its success. More than 2,000 were eventually supplied to the Soviet air force, and 400 more to the Czech air force. Others were supplied to Bulgaria, East Germany, Hungary and Romania.

Straightforward, rugged and easy to fly, the L-29 was ideal as both a primary jet trainer and as an advanced combat/weapons trainer. The Delfin was later exported to several other nations including Egypt and Indonesia. A small number of a single-seat version, the L-29A Delfin Akrobat, was produced, but it never caught on.

In recent years, the L-29 has become popular on the jet warbird market, mostly in the USA, but also in England, Italy and South Africa.
