See also Hochet-Mengin.

Engine manufacturer known as "Etablishements Pierre Mengin" who started building Mengin engines for light aircraft in 1933.

-Later the engines were designed by René Poinsard sometimes known as Poinsard or Mengin-Poinsard.

-The GHM was designed by Genete, Hochet and Mengin and gave 40 CV at 2,300 rpm and 54 CV at 2,550 rpm. It had double ignition and was from the year 1938-40.

-From Hochet we know the models 2A, 2B, 2C, 2Y, 4A, etc. And also the Z series, ZA.

-In the Hochet-Mengin chapter illustrations of these engines are shown.

“Mengin ads”

-Mengín specially made the 2Z and 2Y, like the one in the below illustration but also the 3X a three-cylinder radial, of which we have no further information.

-There were "B versions with gearbox, giving 28 CV at 2,500 rpm. These engines could be obtained with double ignition.

-Poinsard's 2A.01 was Mengin's 2C, giving 38 CV at 2,500 rpm.

-A horizontally-opposed 4 cylinder engine gave 80 CV at 2,250 rpm. It had double ignition and was from the year 1940.

“Mengin 2Z”

-Mengin's two ads feature their engines that were designed by Poinsard, especially the opposed-cylinder ones.

-The best known applications of the Mengin were:
The 30 CV on the SFCA Taupin, the 35 CV on the SFAN4, the 34 CV on the Dasplat 3, the 30 CV seen on the SIPA A50 and several from 32 to 36 CV on the Mignet “Pou du ciel”.

-In the engine reserve stock of the Le Bourget Air Museum there is a nice Mengin. (AZ-).

“Mengin twin-cylinder”

-The small "Elytroplan", exhibited at the MAE, "Avions Anciens" sector, has a Mengin engine with a direct propeller.

-Unlike the one in the Reserve Warehouse (photo above) that has its valves at an angle, this one does not: they are parallel.

-And it has a curious exhaust system. It is the 2A-01 that gave 35 CV.

“Mengin engine on the Elytroplan”

-To better understand the Mengin, see their relationship with Poinsard, Hochet-Mengin, Genete-Hochet-Mengin and GHM.

-The engines built at the Pierre Mengin Establishments were designed by René Poinsard.

-We provide new images of the B engine, in its two versions with single and double ignition.

“Mengin-Poinsard B, with one magneto”

“Mengin-Poinsard with two magnetos”

-The B gave 28 CV at 2,500 rpm. Geared, it reached 32 CV with the propeller rotating at 1,580 rpm.

-The type C, which also was a two-cylinder gave more power, 35 CV at 2,280 rpm increasing to 38 CV at 2,500 rpm.

-The GHM model (see Hochet and Mengin) was larger, giving 54 CV at 2,550 rpm. The initials GHM are from Genete-Hochet-Mengin.

“Mengin 3-cylinder radial”

-To Mengin is attributed a three cylinder radial, shown above. It is from the year 1935.

From Appendix 9: At the Vraux aeronautical museum, a Mengin-2 was found in a deplorable state.

“Mengin 2” (AEHS)

-However, an impeccable Mengin 2A-01 is preserved at the Laatzen museum.
