DCTA 14-X

The 14-X is a Brazilian scramjet engine in development by the Aerothermodynamics and Hypersonics Laboratory Henry T. Nagamatsu of the Institute of Advanced Studies (IEAv) of the Department of Aerospace Science and Technology as part of the PropHiper (Portuguese: Projeto de Propulsão Hipersônica 14-X).

[3] The Brazilian Air Force conducted the first qualification test flight of the 14-X engine on 14 December 2021 from the Alcântara Space Center.

[4][5][6][7] Brazil conducts studies in the field of aspirated hypersonics since 1990s,[1] but a development plan was conceived only in 2007, through the PropHiper project, made official by the Air Force in 2008,[8] when the engineer-captain of the Brazilian Air Force, Tiago Cavalcanti Rolim, started a master's degree at the Instituto Tecnológico de Aeronáutica (ITA) and was approved with a thesis on the waverider configuration.

On 2 December 2021, the Air Force's Department of Aerospace Science and Technology (DCTA) announced the beginning of Cruzeiro Operation seeking to conduct the first flight of the 14-X.

[9] The first test flight of the 14-X scramjet engine took place at the Alcantara Space Center, using a Hypersonic Technology Demonstrator Vehicle named 14-X S .
