Jacques Gérin's « Varivol » Projects

[hesham]

From Aviation magazine 1953,

a good view to a Model.

 

[hesham]

And from La Fana and TU magazines,I can say as only my speculations ;

1924/25 was a flying car patent,with pusher engine
1927 was a biplane patent to proof the concept
V.1 Varivol was the first airplane as a well known one,1929/30
V.2 was a 4/6 passenger tourist airplane Project of 1934,powered by one 200 or 300 hp engine
V.3 was an experimental monoplane Project of 1934,with large variable surface wing area
V.4 was a 10/12 passenger small transport sesquiplane Project of 1934,powered by two push-pull engines
V.5 Arbalète was a transatlantic large transport biplane Project of 1935,powered by four (each two in pair)
860 hp engines
V.6E was a single seat racer monoplane of 1936

From L'Auto 1930,

a strange Info,that his aircraft had estimated speed from 300 to 700 km/h ?.

Also I can add,

V.7 ? was a monoplane with triangle wing, 1938 project with a 140hp engine, maybe transformed into the Varivol II completed at Bréguet factory during the German occupation.

A translation,

Against the loss of speed —The Association Française Aérienne yesterday gave its
second session on the study of the loss of speed. Mr. Henry Potez spoke of the "beak of security" which will be presented in flight on Saturday at 4 p.m., at Le Bauget. Mr. Lachassagne exposed his variable wing-surface, and M. Gérin his
variable surface aircraft project, with figures of 500 kgs per square meter and speeds of 300 to 700 km per hour. The session was followed with interest by many technicians.

Hi,

the V.6E was a single seat low-wing racer monoplane,also with variable surface wing.

Here a short video clip at X (fka twitter(showing the Gerin V-6E during wind tunnel tests.
