Argentine Weapons: The Argentinian V-1

V 1  Project

In March 1950, a pulse jet was developed by Dr. Günther Dietrich for a flying bomb. The payload was 1000 kg, remotely guided as a ground-to-ground projectile, similar to the German V 1. The laboratories of the Special Projects Division worked with a mixture of ammonium nitrate, calcium nitrate and dinitrobenzene; It had an electric impact fuze, an omnidirectional mechanical impact fuze, and a clockwork-actuated delay fuze; The system was intercommunicated, so that one of the three fuzes always detonated. It developed 500 kg of thrust and lasted 45 s. The test bench was in charge of Rizo E. Catón.
Simultaneously, Eng. Pelkas developed a stato-jet, and Dr. Günther Dietrich, together with the designer Guido Galán, developed a pulse jet with 80 kg of thrust (the dynamic test was carried out on an INSTITEC automobile chassis). Pulse jets with 14 (valve-operated) and 16 kg (Scopette type) thrust were built and tested, the former to power helicopter rotors, and the latter to be used in the self-propulsion of gliders.



Pulse jets (unidentified: in 1988 much of the historical documentation of the FMA that was in the Statistical Section disappeared).

Argentinian Engine Production

Argentine Engine Production

I.AE. 16 EL GAUCHO ENGINE
Argentina had applied to the American company WRIGHT AIRCRAFT ENGINES, a manufacturer of radial engines, for a license to build an engine with a power of close to 400 CV in Córdoba. It was granted in 1938 but subsequent commitments to supply engines for the aircraft of the US Air Force itself on the occasion of World War II, closed the shipment to Argentina of the material to build them, as well as forging molds, gauges and documentation. .

The experience acquired when the WRIGHT CYCLONE was built (and the rest of the engines under license) and the general scarcity of raw materials to supply the operation of the Factory, led Commodore Ing. Juan Ignacio San Martín, CEO of the Instituto Aerotécnico (FMA), to plan the production of national engines and to put into operation three necessary and very new technologies for Argentina:

- Manufacture of aeronautical plywood for coating that was imported from Finland (spruce pine), from the country's wood in new plants built within the Aerotechnical Institute;
- carry out the forging of steel parts, as well as the casting of aluminum alloys (Forging and Foundry Area of the Institute);
- locally produce carburettors, magnetos, #53 fuel pumps.


Assembly line of the latest series of radial engines I.Ae. 16 of 450 hp. 1946.

For manufacturing the engine, in addition, official intervention was given for the first time to the private industry of Córdoba and the Buenos Aires city. A tender is launched involving companies and workshops #54 for the production of loose parts, some of these businessmen had been trained at the Military Aircraft Factory. First Argentine conception and design aviation engine, the I.Ae. 16 EL GAUCHO was built to equip advanced training aircraft I.Ae. 22 DL, and started up for the first time on June 27, 1944. Fixed radial type engine, simple 9-cylinder star, air-cooled, with a maximum takeoff power of 450 CV at 2250 r.p.m. and an hourly consumption at cruising regime of 80-liter.
