The T.30 would be a welcome addition and the proposed VEMA 51
would have been indeed identical to the Macchi MB-320.

The Guerchais-Roche SA.103 was simply 160 examples of the famous Emouchet glider built during 1946-1948 by Roche-Aviation.

Hi,


the Guerchais began its career in aviation by designed the 1-01 sailplane
or a gilder monoplane of 1922.


Then he formed a company with Hanriot in 1928,and he started with T-1,
it was a project for light aircraft,may be a high-wing configuration,that's
because,it made the designers to inspire the T-2,powered by one 60 hp
Salmson 9 Adr engine.

The Guerchais-Henriot T.2 was entered in the economical aeroplane contest at Orly in August 1928.

The goal of the contest was to encourage the demonstration of practical aircraft, preferably two-seaters, comfortable and capable of carrying 15-kg mail bags over 400 km non-stop, and to climb up to 1,500 m in 30 minutes with full load. No limitation was placed on engine power, but empty weight was limited at 400 kg.

Evaluation was based on a series of technical tests, which included an altitude test, a take-off and landing test, a disassembly/reassembly test, and a speed test. The qualities of takeoff, climb, seating arrangement, fireproofing, wood or metal covering of wings, assembly/disassembly, automatic engine start, dual controls, protection against rollover, visibility, comfort, protection against noise, etc., all added up to increase the aircraft's mark.

A final and decisive efficiency test consisted in a 400-kilometer closed circuit.

Once this series of tests was over, the remaining contenders had to run a series of daily 250- to 400-km legs in a 2,200-km aerial Tour de France.


25 types were initially entered (though 25th aircraft is unaccounted for):
  • 15 French aircraft: Caudron (6), Albert (4), Guerchais (1), Mauboussin (1), Leduc (1), Nessler (1), Peyret (1).
  • 3 German aircraft: Klemm (2), Baumer Aero (1).
  • 6 English aircraft: C.L.A. 4 (1), Avro Avian (3), De Havilland Moth (2).
10 aircraft were eventually retained:
  • N°1: Caudron with 40 hp Salmson engine.
  • N°3: Caudron with 60 hp Salmson engine.
  • N°4: Caudron with 60 hp Salmson engine.
  • N°6: Caudron with 60 hp Anzani engine.
  • N°9: Klemm with 40 hp Salmson engine.
  • N°10: Guerchais with 50 hp Anzani engine.
  • N°14: Albert with 40 hp Salmson engine.
  • N°18: Avro Avian with 85 hp Cirrus engine.
  • N°20: De Havilland Moth with 85 hp Gipsy engine.
  • N°25: Avro Avian with 85 hp Cirrus engine.
The Guerchais T.2 was a small two-seat "limousine" cabin type with dual controls, piloted by Lemerre, who aimed to prove that flying was a sport like any other andmade a point of performing his Tour de France wearing a straw hat and light gloves. It finished the contest in sixth position, behind a Caudron but ahead of an Albert and the other two Caudrons that were running.

Louis Guerchais was partnered with Louis Henriot not René Hanriot. This is a very common error/typo (Hanriot's 1920s-1030s trainers are invariably listed as 'Henriot' designs).

BTW, an ebay ad mentions "Avions Hydravions GUERCHAIS-L. HENRIOT" as a title in Locomotion Aerienne - Les Ailes - 9ème année, n° 450, 30 janvier 1930. Might these hydravions make up some of the 'missing' Guerchais-Henriot designations?

Also the Guerchais had many unnumbered Projects;

- Single seat light aircraft,equipped with engines ranged between 35 up
to 60 hp,developed from T-3 & T-4.

- Two seat light aircraft,equipped with engines ranged between 45 up to
75 hp,based on T-2.

- Three seat light aircraft,equipped with engines ranged between 70 up
to 100 hp,developed from T-5 and T-8.

- Four seat (up to ten seat) light aircraft,equipped with ranged between
120 up to 180 hp,maybe it was T-7,as they suggested in TU magazine.
