Magni MT-7 / VPM S-2

TerryLeave a comment

In 1980 Vittorio Magni of Italy had designed a new, two-seat autogyro with a 150 hp Lycoming engine. The machine got the project name MT-7 (Magni-Tervamaki). Vittorio later redesignated the machine as VPM S-2.

The calculations and general design blueprints were delivered to Vittorio, who was responsible for all the detail design. He also built the machine together with his son. The machine was completed in 1985, and it also flew well.

Some years later the machine was lost in an accident in France. The control rods had been bent in road transport by a truck.

Magni continued the development of autogyros and has designed a series of gyros which all seem to have the rotor head and blade design of JT-5 and MT-7.

Maestranza Central De Aviacion H.F.XX-02

Designed by Hugo Fuentes (hence the HF in the designation), the HF XX-02 trainer was a conventional, low-wing cantilever monoplane of mixed construction with fixed tailwheel undercarriage. The pilot and instructor sat side by side.

Two prototypes were constructed at El Bosque Air Base, designated XX-02 and XX-02B, and the first flew in 1954. Development was abandoned due to difficulties maneuvering at lower altitudes, which in one case, led to a crash in which the instructor was killed while attempting to land after a tight turn at low altitude.

The design was subsequently refined by Francisco Bravo and an improved version, the HFB XX-02 flew in 1958 powered by a Continental O-470 engine in place of the Ranger L-440 that powered the original. Only the two were ever built.

Maestranza Central De Aviacion Triciclo-Experimental / XX-01

TerryLeave a comment

In 1947, the Maestranza Central de Aviación, the Central Workshops of the Chilean Air Force designed and built the first Chilean-designed aircraft, the Triciclo-Experimental (also designated XX-01), unveiled in May 1947. The Triciclo, designed by Alfredo D. Ferrer, was a low-winged monoplane of wooden construction with a fixed tricycle landing gear and a twin tail. The crew of two sat side-by-side in an enclosed cockpit, and were provided with dual flight controls.

Built with indigenous materials, Ferrer received tuition in the XX-01.

Only one was built.

Maer The Egg / The Fly

TerryLeave a comment

A machine built around 1924, consisting of an egg-shaped fuselage with an underslung gondola and extra-long landing gear that could be found at Stinson Field at the time. A mid-wing monoplane, the 90hp Curtiss OX-5 engine was mounted in a cowl that looked much like a NACA cowl, not then invented, and its radiator was mounted on the outside of the cowl.

The ship was said to be the brainchild of a German inventor, and one named Maer was known to be working at Stinson Field, but other sources credit it to a Prof Warner, who also designed an ornithopter.

An Air Service Newsletter lists the plane as “The Fly,” designed and constructed by a Lt D B Phillips, assisted by members of the 3rd Attack Group.

Reportedly was Charles Lindbergh who labeled it “The Egg” when he saw it.
