摘要
An engine (100) contains at least one pulse detonation combustor (103) havingacombustion chamber (106) and an exit nozzle (107) coupled to and downstream ofthecombustion chamber (107). During operation of the at least one pulsedetonationcombustor (103) a detonation occurs within the combustion chamber (107) and atleast one of a fuel fill fraction and purge fraction of the at least one pulsedetonationcombustor (103) are utilized to offset a temperature peak of said detonationfrom apressure peak of said detonation. The fuel fill fraction is defined as 1 -purgefraction, and the purge fraction is the ratio of the purge time of the atleast one pulsedetonation combustor (103) to a sum of the purge time of the at least onepulsedetonation combustor (103) and a fuel fill time of the at least one pulsedetonationcombustor.
