The Fouga CM.170 Magister is a 1950s French two-seat jet trainer aircraft, developed and manufactured by French aircraft manufacturer Fouga. Due to industrial mergers, the aircraft has been variously known as the Fouga CM.170 Magister, Potez (Fouga) CM.170 Magister, Sud Aviation (Fouga) CM.170 Magister and Aérospatiale (Fouga) CM.170 Magister, depending on where and when they were built.

In 1948, development commenced at Fouga on a new primary trainer aircraft design that harnessed newly developed jet propulsion technology. The initial design was evaluated by the French Air Force (Armée de l'Air, AdA) and, in response to its determination that the aircraft lacked sufficient power for its requirements, was enlarged and adopted a pair of Turbomeca Marboré turbojet engines. First flying on 23 July 1952, the first production order for the type was received on 13 January 1954. Export orders for the Magister were received, which included arrangements to produce the type under license in West Germany, Finland and Israel. In addition, the related CM.175 Zéphyr was a carrier-capable version developed and produced for the French Navy.

While primarily operated as a trainer aircraft, the Magister was also frequently used in combat as a close air support platform by various operators. In the latter capacity, it saw action during the Six-Day War, the Salvadoran Civil War, the Western Sahara War, and the Congo Crisis. In French service, the Magister was eventually replaced by the Dassault/Dornier Alpha Jet. After its retirement by the French Air Force, Magisters were purchased by several private-owner pilots in the US and have since been operated in the experimental category.

Development

During 1948, aircraft designers Robert Castello and Pierre Mauboussin at French aircraft manufacturer Fouga embarked upon the design of a new jet-propelled primary trainer aircraft, initially designated as the CM.130, intended for the French Air Force (Armée de l'Air, AdA) as a replacement for piston-engined Morane-Saulnier MS.475 aircraft. The AdA reviewed the project and found that the aircraft lacked power from the two Turbomeca Palas turbojet engines selected for the aircraft; in response, Fouga proceeded to enlarge the basic design, which was equipped with the more powerful Turbomeca Marboré engine and retaining the distinctive butterfly tail of the Fouga CM.8 glider, which had been used by Fouga for jet engine research.

During December 1950, the AdA placed an order for three prototypes; on 23 July 1952, the first aircraft conducted its maiden flight. During June 1953, a pre-production batch of 10 aircraft were ordered, which was followed by an initial production order for 95 aircraft on 13 January 1954.[1] By October 1955, all 13 preproduction Magisters had been completed, while the first flight of the first production aircraft was imminent. Also scheduled to fly early in 1956 was the CM.171, which functioned as a test aircraft for the envisioned CM.195 swept-wing, butterfly-tailed trainer.

In order to manufacture the type, Fouga opened a new assembly plant at Toulouse-Blagnac within a newly built complex. According to aviation publication Flight International, any export orders that were received were typically given priority over the existing orders which had been issued by the French government; this policy allowed for overseas countries to procure aircraft directly "off the line" with minimal delay between receipt of orders and the corresponding deliveries.

The Aéronavale (French naval air arm) decided to adopt a carrier-capable derivative of the Magister, the CM.175 Zéphyr, which served as a basic trainer for deck-landing training and carrier operations. These were preceded by two "proof of concept" prototypes, designated the CM.170M Magister, which performed their first flights in 1956 and 1957 respectively.

By 1960, in excess of 350 Magisters had entered in service with various operators; according to Flight International, production within France had attained a completion rate of five aircraft per month, while the projected total of French-built Magisters was reportedly expected to eventually top 600 units. The type was also being produced overseas under licensed production arrangements in West Germany, Finland and Israel.[5] The first export customer for the Magister was West Germany, who placed an initial order for 62 aircraft directly from Fouga; a further 188 aircraft were produced by Flugzeug Union Süd (a consortium of Heinkel and Messerschmitt)[6] under license.[1] In addition, the Magister was also constructed under license by Finnish company Valmet and by Israeli firm Israel Aircraft Industries (IAI). As a result of these arrangements, a combined total of 286 aircraft were completed under license.

From 1960, an improved version of the Magister, designated the CM.170-2 Magister, was produced, which was powered by a more powerful Turbomeca Marboré IV engine. During 1962, production of the Magister was terminated in France but continued to be constructed under licence in Finland up to 1967. The development of the aircraft had been brought to an end in response to the AdA selecting the rival Alpha Jet as its new jet trainer instead.

Design

The Fouga CM.170 Magister was developed to perform both basic and intermediate training activities.[7] It is a compact, tandem seat aircraft with performance akin to larger, more powerful aircraft. Comparatively, it was a higher performance aircraft than the rival British-built BAC Jet Provost, and was considered by the Aviation magazine Flight International to be comparable to Fokker S.14 Machtrainer.[8] It featured a distinctive butterfly tail configuration; a conventional tail was tried but found to be aerodynamically inferior at higher speeds. A keel fitted under the rear fuselage functions to reduce the negative dihedral effect of the butterfly tail during rudder applications.

The Magister was powered by a pair of Turbomeca Marbore turbojet engines, which provided 880 lb of thrust each; it was promoted as offering "twin-engine safety with single-engined flying characteristics". The two engines, which were placed close to the centre line, produced very little asymmetric thrust as a consequence; this was viewed as a valuable safety feature for a trainer aircraft.[10] While viewed as an uncommon instance, in the event of a single-engine flameout the relighting procedure was relatively quick and easy to perform. The rate of acceleration and rate of climb were less than contemporary frontline jet fighters, such as the de Havilland Vampire and Gloster Meteor, but was in excess of many of the previous generation of piston-engined trainer aircraft.[11] The engines shared a common fuel system, but had independent oil systems; for extended range, tip tanks were provided as standard equipmnt.

The desig of the Magister paid close attention to simplicity of operation; as such, a minimum number of procedures were necessary prior to take-off.[13] Accessibility to both the engines and onboard equipment for servicing was above average; it was possible for both of the type's Marbore engines to be swapped out within 45 minutes. Provision was made for the installation of a pair of 7.5 mm guns upon the aircraft's nose, which included a 200-round ammunition box for each gun and the ability to collect both links and cases. Underwing hard points could be used to hold up to four rockets or a pair of 110 lb bombs.[4] A landing light was installed in the tip of the nose while a retractable taxiing light was installed upon the Messier-built nosewheel.[4] The landing gear was satisfactory for operations from austere grass airstrips.

The Magister was typically outfitted with avionics such as very high frequency (VHF) radio systems, Lear radio compass, and intercom; all cockpit electronics conformed to NATO accessibility standards.[15] It was not provided with ejector seats in standard, but the fitting of various units was considered to be available upon request. The assorted levers, switches and dials that comprised the cockpit displays were typically easily observable, while ample room was provided for pilot comfort and space to accommodate a parachute.[16] The standard blind panel is ahead of each pilot, and engine instruments are set to the left, while underneath these are the flap indicator, flap switch and emergency selectors, along with the two throttles and fuel cocks; the right forward bench carries the radio panel, and to the extreme right of that are the armament controls. The cockpit was pressurized as well as being provisioned with a fresh air system.

The pedals were adjustable and had fairly permissible limits, while the cockpit itself was relatively easy to access, the canopy opening upwards and rearwards while using only a single step due to its low height.[16] In order to account for the poor forward visibility available to the rear seat, usually occupied by the instructor, the front screen was bulged and a binocular periscope was fitted, providing a relatively clear perspective over a relatively wide angle over the top of the front cockpit. The forward cockpit, normally used by the student, provided for excellent external visibility.[13] According to Flight International, the Magister was able to perform various aerobatic manoeuvers "effortlessly", the flight controls were light and relatively well harmonized, and the stick has a firm sense of feel.[11] It had a high level of lateral stability in flight, as well as being fairly directionally stable as well, allowing the aircraft to, when properly trimmed, be flown hands-off for indefinite periods.
