This study assesses the global market potential for supersonic airline transportation by evaluating worldwide premium ticket sales figures based on so-called marketing information data tapes (MIDTs). Origin-destination demand data were collected from an internet database and subjected to various processings and additions. After discussing factors of influence regarding market response, the final data files are used to estimate possible future demand for variously sized supersonic airliners. Nomenclature LOS = Length of stay MIDT = Marketing Information Data Tape O/D = Origin-destination (city pair) SST = Supersonic transport

We lay out the thesis that modern supersonic air transportation has the best chance of realization by commencing with small aircraft. A possible implementation path is described with reference to the Aerion AS2 supersonic business jet. Further, the paper entails an overview on the economic and operational challenges of supersonic airliners.

Due to steadily growing air traffic, airports need a means to evaluate the capability of their infrastructure to handle future air traffic movements. Sound forecasts are needed for fundraising, within lawsuits, and in order to avoid misplanning. The quality of current forecasts is often queried. Hence, this work introduces parts of a tool chain that derives future air traffic movements out of transport scenarios and compares them to the capacity of an airport. Five consecutive models within the chain yield future air traffic movements for one airport considering passenger demand, a forecast of aircraft movements, airline preferences and airport capacity.

In this work, the design methodologies and technical rationales for the design of JAXA's low-boom S4 (System integration of Silent SuperSonic airplane technologies) airliner are detailed with a focus on aerodynamic engine-airframe integration with respect to efficiency and sonic-boom abatement, respectively. The approach to high-fidelity CFD grid generation, flow simulation, and signature propagation for sonic boom assessment is explained, resulting in sonic-boom data maps with respect to flight physics parameters. Thereafter, DLR inserts the aircraft in operational scenarios for supersonic overland prohibition and permission, respectively, based on forecasted origin-destination passenger demand. Overwater flight routes are designed for the restrictive scenario, and the S4's flight performance data are used to simulate flight missions on all routes, yielding flight durations. Eventually, the respective market sizes for S4-type airliners are estimated and discussed.
