Dual mode ramjet

Web20 set 2024 · The dual-mode scramjet bridges the gap between the ramjet and scramjet, using the same combustor for both combustion modes but operating with a thermal throat in the ramjet mode. This may theoretically enable a vehicle to be operated from flight Ma ≈ 3 to Ma ≈ 8 with only minor engine modifications. WebThe typical height of the whole dual-mode ramjet is between 2.4 and 3 m at maximum capture, the typical total width is 10 m (could be divided in several modules), the engine length (internal duct only) is 5 to 6 m.
