Overview
A Russian-derived fighter engine for upgrading French-built fightersIn the early 1980s Klimov design engineers drew new versions of the RD-33 fighter engine, then in full production, tailored to the propulsion of single-engined aircraft, notably updated versions of the MiG-21. In 1990 these studies went ahead into full design, known as the RD-33N, and were broadened to incorporate installational changes to enable this engine to serve as a common baseline power plant able to power not only later versions of the MiG-21but also the Mirage III, 5 and F1. Features include a completely new accessory gearbox on the engine's underside (in the previous versions of the RD-33 it had been on top, dictated by the design of the MiG-29), as well as a gas-turbine starter, oxygen injection for automatic relight under all flight conditions, twin 40-kVA alternators to give increased electrical power, high-capacity fuel and hydraulic pumps, and an advanced semi-computerised hydro-mechanical fuel control giving 'carefree' handling.
Overview
SMR-95A This, the first version of the SMR-95, was configured to fit the Mirage F1.AZ. The accessory-drive gearbox is the AADG-52. No change in aircraft centre of gravity or thrust line was necessary, and only a slight shortening of the fuselage was needed to match the new and more efficient multi-flap nozzle. Flight testing began in mid-1994. The extra thrust transforms flight performance, while the combat radius is significantly extended by the greatly reduced fuel consumption, reduced engine weight (about 200 kg, 440 lb) and increase in permissible take-off weight of about 1,000 kg (2,205 lb). Further advantages include better stability during gunfire, and faster engine acceleration, the time from flight idle to maximum rpm being only 3.5 seconds, with another 2.0 seconds being needed to bring in full afterburner.Some 70 test flights were made with the re-engined F1.AZ, Overall, radius of action was increased by 25 per cent, and combat effectiveness increased by factors from 1.2 to 3.0. However, the final decision was to retire the 30 F1.AZ aircraft and put them up for disposal (the replacement being the Gripen). Despite this decision, Marvotech ) conducted a phased flight-test programme in support of an upgraded Mirage F1 initiative. This involved not only the new engine but also a "glass cockpit" and new avionics.,
