Turbomachine and a detonation chamber flying object provided with such a turbomachine

- According to the invention, the chamber (4) of the turbomachine (1) comprises a motor (6) in continuous wave detonation, provided with an annular detonation chamber (7) and associated means (8, 9) for generating a continuous production of hot gases from an explosive mixture of fuel and air, said motor (6) continues detonation wave being arranged to form, from an incoming air stream ( E) a first stream (F1) which penetrates into the detonation chamber (7) and which is used by said motor (6) and a second stream (F2) which bypasses said turbomachine (1) comprising, in addition, auxiliary means (10) for mixing the hot gases (F3) from the detonation chamber (7) with said second air flow (F2) before directing them to the turbine (5).
