History of aviation Marc Noetinger Mas Palégry
Mauboussin Type X
First flight – December 7, 1928
Better known as Peyret-Mauboussin X, it is a monoplane tourist plane designed by Pierre Mauboussin and Louis Peyret, built in 1928.
It won 7 world records: 5 in the airplane version with Charles Fauvel, 2 in the seaplane version (PMH X bis) with the pilot Vercruysse.
The PM X is a plane initiated by Pierre Mauboussin, then in partnership with Louis Peyret.
It is a monoplane with a high wing built in one piece.
The wing is assembled to the airframe by 4 bolts.
It is characterized by its closed cockpit.
It is equipped with an ABC Scorpion engine which was chosen for its sobriety and its robustness on the advice of the pilot Georges Barbot.
This unique aircraft was built by Peyret in its Suresnes workshop, except for the wing, which was made by Letord in Meudon for reasons of space.
Charles Fauvel, recommended by Peyret, took care of the development.
Registered for the light aircraft competition in September 1928 at Orly, it was not ready in time.
- Ground version
Charles Fauvel wins in September 1929 the 4 international records opened in the category of planes of less than 200 kg3,4
Speed: 139,534 km/h
Altitude: 5,193 m
Distance in closed circuit: 700 km
Distance in a straight line: 852.109 km
When the International Aeronautical Federation reopened the duration record in 1930, Fauvel won it with a flight of 12h 3min 3s (taking back the closed circuit distance record which had been removed shortly before).
In November 1930, and once transformed into a seaplane, the pilot Vercruyse won the world record of altitude (3.461 m) and speed (122,781 km/h) in the category of seaplanes of less than 250 kg.
On December 24, 1930, Vercruyse had an engine failure during a distance record attempt.
He landed safely on a railroad track, but the plane was irrecoverable5.
In 1930, the only one built was converted into a seaplane under the code PMH X bis (for an increase in weight of 32 kg).
- Other characteristics
The sail of 10 m of scale is carried out of only one part.
It is fixed to the airframe by four bolts (which makes it possible to put it back in the axis to facilitate transport).
To enter the category of the planes of less than 200 kg (it initially made 203), Peyret replaces the landing gear without axle by a dural gear with axle…
