FIELD: aircraft industry. SUBSTANCE: turboramjet engine for supersonic and/or hypersonic aircraft designed for operation within wide speed range has housing with at least one adjustable hole made for communication of combustion chamber with atmosphere and delivery of outside air steam into transfer zone to provided variable geometry of zone with gradually converging and then diverging of section along housing length for speeds corresponding to low values of Mach number and approximately constant section in length which then widens slightly for flying speeds corresponding to high values of Mach number. EFFECT: preservation of maximum value irrespective to external conditions. 8 cl, 3 dwg
