According to an article signed by aeronautical engineer M. Cuesta in the magazine Aeroplano, the following information has been recovered.

-In 1935, Ensign Virgilio Leret patented a “Continuous Reaction Compressor Motor-turbojet”, which was only left in project when V. Leret died in 1936, at the beginning of the Spanish Civil War.

“Leret's design”

From Appendix 7: This beginning of 2012 and thanks to AENA and ETB, much memory of Virgilio Leret's work has been recovered. A magnificent report from the Docufilia series reviews the last days of his life, faithful to the legality of the Spanish Republic and that he was assassinated on the first day of the coup by the rebels.

“Virgilio Leret”

-In the main text there is a call to his invention: a continuous combustion reaction engine. A non-defining scheme is provided. It was thoroughly studied by Martin Alvarez Cuesta (QEPD) in the magazine Aeroplano.

"Modern vision of possible application"

-Thanks to the development of a 3-D design by Tomas Diez we see a description of its operation.

We must place ourselves in 1936 to understand the solutions that Leret gave to each part of the engine.

-The compressor was typical of the time, radial centrifuge with one active side.

-A turn is made at the periphery of the compressor housing and in a certain way it acts as a diffuser, but there are individual outlets to some boxes where small pistons will act as volumetric compressors.

"Appearance of the compressor and its front intake"

"Air rotation and exits towards the piston chambers"

“Reduction gear for the impellers that drive the pistons”

"Impeller with blade driven pistons"

"The pistons compress the air again"

"The first three in the first stage, then two and one"

"Finally the fuel is incorporated and they act as
torches. First turbine without guides and in the second
step does have them "

“There is a great dispersion in the nozzle, which suggests a weak thrust.
We are talking about 1936 ”- (Requested for reproduction permission from AENA and ETB).

From Appendix 9: The inventor of the turbojet of his name, died violently on the first day of the Spanish civil war in a tragic way. For maintaining their fidelity to the Republic

-Now we have seen a singular obituary from Caracas in the newspaper "El País" on July 17, 2012, of their daughters and grandchildren, in memoriam. With a comment that does popular justice.

“Commemorative notice for Leret's death”

-In the month of March 2014 a model of the engine designed by Virgilio Leret Ruiz and patented in 1935 was exhibited at the Aeronautics and Astronautics Museum of Cuatro Vientos.

“Maqueta del motor de Leret”

-It is the “Continuous Reaction Motor-Turbojet”, a different turbojet than the Germans (Von Ohain) and the English (Frank Whitlle) were making.

-It has been studied by technical people resulting in considering it completely viable.

-The model has been built according to the documents available by the model designer Camilo Garcia Rojo. In the magazine Aeroplano published by the Ministry of the Air a few years ago we had news of this engine.

-Not to forget that Leret was faithful to the Republic and for having opposed the rebels on July 17th (one day before he is listed as the coup official, on July 18) he was shot for it and his work was silenced.

-The Basque Television, Euskal Televista, has done a memorable job -video- about his person and project. Now there are already many pages on the Internet that deal with Leret's invention. His daughter Carlota has promoted many events so that his memory is not forgotten.

“The same engine exposed”

-This last photograph is just as it appears in an article of <Aerotendencia.com>. The previous one is from the ADAR magazine.
