“…The legacy of SSTs of the past failed in this respect as the technology needed to be developed further to allow propulsion systems to be economically viable and environmentally compatible. 8 Since the Concorde and the Tu-144, the performance of aircraft engines have been enhanced through three leading technologies: better materials and manufacturing processes, the advent of variable cycle engines (VCEs) and variable stator technology. This research extends on an earlier multifactor regression sizing study 9 to determine in greater design detail what the configuration of a 200-passenger Mach 3.0 aircraft could be using extant technology.…”

Despite 50 years of technological advancement since the inception of Concorde, research on supersonic passenger aircraft has only recently resulted in design and flight test of several small 12 to 55-passenger business jets with supersonic cruises between Mach 1.2 and 2.2. Analytical research designs of larger 300-passenger aircraft have been conducted only to speeds of Mach 2.0 and 2.2, mainly avoiding moving beyond turbojet propulsion. This research extends on an earlier multifactor regression sizing study to determine in greater design detail whether the configuration of a 200-passenger Mach 3.0 aircraft is feasible using extant technology. This research article is the second part of two and covers a suitable and cost-effective propulsion system for the executive supersonic passenger aircraft. Through this high-speed design, the research examines modern propulsion technology and the performance advancements it affords through higher efficiencies, higher metallurgical thermal limits, variable cycle engines and variable stator technology. The analysis was conducted on several potential propulsion systems using GasTurb software to obtain engine performance data. The performance results led to a combined cycle turbofan–ramjet engine as being the engine that could yield the most extensive range for the aircraft. Further investigation is needed on aircraft noise, engine emissions, the accuracy of the thrust-critical lift-to-drag ratios and the aeroelastic effects that can be closely coupled to noise and performance.

“…Several concepts have been developed to reduce high speed jet noise, usually involving efforts to enhance the mixing between the jet and the surrounding air. These methods reduce the length of the high velocity region of the jet where noise is generated the noise in some way [18,27].…”

“…Development of a supersonic business aircraft would leverage the extensive know-how and technologies developed for military airplanes, but hinges on effective reduction of take-off noise generated by supersonic jets exhausting from the engines of such aircrafts [28]. So far, the bulk of the supersonic noise suppression effort has encompassed mixing enhancement and ejector approaches [29,30] which typically lead to large and heavy power plants [31]. One may wonder if supersonic engines will follow the same evolution as subsonic engines, leading to supersonic high-bypass turbofans.…”

The large velocity ratio and the presence of Shocks in the exhaust plume from low bypass engines or supersonic jetliners cause jet noise to be dominant component of overall aircraft noise, and therefore is an important issue in design of the next generation of civil supersonic transport. Jet noise reduction technology also has application in the design of highperformance tactical aircraft. Jet noise is of particular concern on aircraft carriers where it is necessary for deck crew to be in relatively close proximity to the aircraft at takeoff and landing. In this paper, a brief discussion about supersonic jet noise sources and a review of the main passive technologies employed for the reduction of supersonic jet noise are presented.

Turbofan engines are commonly used for commercial transport due to their advantages of higher performance and lower noise. Jet noise is one of the principal noise sources of turbofan aeroplane engines and remains an acute environmental problem that requires advanced solutions. The ever-increasing demand for quieter engines requires the exploration of alternative techniques that could be used by themselves or in conjunction with existing methods. Significant progress continues to be made with noise reduction for turbofan engines. Analytical and semiempirical models have been developed to investigate the influence of some design tools when they are employed in a multidisciplinary optimisation framework. This paper discusses the major components of jet noise in turbofan engines and presents a review of jet noise reduction technologies.
