Fougaman

We are getting our Finnish Fouga ready to fly more often.

Shown here when it first moved to the museum in '07, it is still one of the most asked about aircraft because of it unique V-tail design.

Jon is one of our all-around generalists, he can fly-em and he can fix-em. Recently he tackled the task of replacing the on-board batteries. Originally equipped with finicky (and expensive) Ni-Cads, we recently found it was time to replace the batteries once again.

Here, Jon is installing our favorite replacement, an "Odyssey" battery set. With roots in the Hawker Siddeley group, Odyssey manufactures batteries used in demanding commercial applications.

As anyone who has dealt with the "system" can tell you, it takes additional time and money for a product to receive Mil-spec or FAA-PMA approval. In the best of all possible worlds, "COTS" or "Commercial Off The Shelf" technology can be one or two generations ahead of governmental procurement. Fortunately for us, this is one of those times that we can take advantage of a well developed commercial technology.

Perched on the Fouga, working in the battery compartment, Jon looks ready to imitate Major Kong in the 1964 classic cold war movie "Dr. Strangelove".

The Whistling Turtle (Belgian Air Force nickname)

In 1948, Fouga designed a jet-powered primary trainer for the French Air Force (Armée de l'Air, AdA) to replace piston-engined Morane-Saulnier MS.475 aircraft.

When AdA found the aircraft lacking in power from the two Turbomeca Palas turbojets, Fouga enlarged the basic design and used the more powerful Turbomeca Marboré engine. The distinctive V-tail of the new CM.170 Magister originated on the CM.8 glider Fouga was using to experiment with jet engines.

In December 1950, AdA ordered three prototypes, with the first aircraft flying on 23 July 1952. A pre-production batch of 10 were ordered in June 1953 followed by the first production order for 95 aircraft on 13 January 1954. Fouga built a new assembly plant at Toulouse-Blagnac to produce the aircraft. The aircraft entered service with AdA in 1956. The French Navy's Aeronavale adopted a derivative of the Magister, the CM.175 Zéphyr, as a basic trainer for deck landing training and carrier operations.

Finnish Fougas

In 1958-1959, Finland purchased 18 Fouga Magisters from France. At the same time they also obtained a manufacturing license. The Finnish aircraft manufacturer Valmet (the Finnish equivalent to United Technologies or Lockheed Martin) later built 82 Fouga aircraft between 1958–67.

The Museum's Fouga is No. 80 from Valmet. The aircraft was a jet trainer in the Finnish Air Force between 1958-1988. The museum aircraft is currently undergoing an annual inspection and will return to flight shortly. One rather unique feature of the Magister is the use of a binocular periscope in the back seat for pilot vision. Other manufactures have used a series of mirrors for vision blocks, but this aircraft uses the binocular periscope. It gives the aircraft one more unusual feature.

In contemporary literature regarding the performance of the aircraft a method of economy cruise is described in which one of the engines is shut down at altitude and the aircraft continues to perform within 20 kts of normal cruise speed. Much of this ability is due to the wing design. Based upon the CM-8 glider, the aircraft provides exceptional engine out performance.

In addition, many nations purchased Magisters for trainer and light-attack duties. In the latter role, the aircraft could be fitted with two 7.5-mm or 7.62-mm machine guns in the nose (the museum Fouga is so designed, with covered gun ports), several combinations of underwing rocket pods or freefall bombs, and even Nord AS.11 air-to-surface missiles. Israel proved the Magister's combat worth during the Six Day War in June 1967, when the Magister flew ground attack missions in Egypt and Jordan.

The Magister design did not change much throughout its production life. The most significant upgrade, the CM-170-2, was fitted with Turbomecca Marbore VI engines, which gave the airplane a 350-pound increase in thrust over the earlier Marbore IIs, resulting in a higher useful load and greater climb rate. The more powerful engines were also used in the CM-170-3 Super Magister, operated by the Irish Air Corps as a light attack/trainer well into the 1990s.

More information and pictures of the Museum's Fouga can be found on the museum's CM-170 web page.

Finished Finnish Fouga

Some problems are good problems to have. For example, the museum has more flyable aircraft than it has pilots... our Fouga hasn't flown much this year, mostly for lack of a pilot.

This particular Fouga is a Fine, Flying Fouga made in Finland. The Fins made 81 Fougas under license from the French (the most lucid answer anyone's ever given to the question "Why does it have a V-tail?" seems to be "It's French!"), this one is serial number 80. Fougas are graceful aerial ballerinas and were used by many, many aerobatic demonstration teams (did you know that Ireland has an aerobatic demonstration team? They flew Fougas for a while.) This one needs only an annual, a sponsor (hey, Nokia!?) and some tender loving care and it would be flying regularly.
