The proposed U.S. HSCT, illustrated in Figure 8.1, will cruise at Mach 2.4 at altitudes up to 70,000 feet. The mainly composite structure airplane will be over 300 ft long, have a 130 ft wingspan, carry up to 300 passengers in a tri-class configuration, and fly 5000 nautical miles non-stop. U.S. Industry and NASA are developing the technology foundation for a High Speed Civil Transport (HSCT) through the NASA High Speed Research (HSR) program as well as independent industrial research and development efforts. An international working group is also studying the feasibility of such an aircraft and laying the ground work for an international agreement on critical regulatory issues such as emissions, noise, and sonic boom. Several studies to date indicate that a potential market of well over 600 airplanes will exist over the period from 2005 to 2015 if the seat cost is relatively close to subsonic airplanes. High productivity, roughly twice that of current aircraft in long overseas routes, is a major factor in compensating for the higher development and manufacturing costs for the HSCT. This paper discusses the control system architectural requirements for the HSCT airplane with emphasis on the potential of high-temperature electronics to improve the operating economics of the system. Most of the discussion centers on the actuation system electronic architecture because it is this portion of the control system that is inherently exposed to the most severe HSCT thermal environment.

The commercial transport industry in the US is presently studying the feasibility of a new generation supersonic transport called the HSCT (high-speed civil transport). The presently planned HSCT is a vehicle with a gross takeoff weight of over 700,000 pounds, a length of over 300 feet, and a supersonic cruise speed in the area of Mach 2.4. It would be capable of carrying 300 passengers with a range of approximately 5,800 miles. The HSCT would cut Trans-Pacific flight times by approximately 60 per cent. Primary advantages are the number of additional trips an HSCT can make per year. This assumes that schedules can be planned that will attract international passengers.
Future advanced long-haul Evacuated Tube Transport (EET) system operated by TransRapid Maglev (TRM): a multidimensional examination of performance
Published in Transportation Planning and Technology, 2019
The ‘what-if?’ operating scenarios are developed for the year 2050/51 when the EET-TRM system is supposed to be implemented between Europe and North America (over the North-Atlantic) and as such to start competing with the well-established APT system. The start/end stations/terminals could be in Southampton/London (UK) and New York (USA), which is a distance of: d = 5564 km. Three operational and competing scenarios are defined by considering the APT system as follows: ETT-APT/C: Conventional sub-sonic aircraft fleet operating at a cruising speed of about 0.85M at altitudes of about 33,000 ft (1M = 1078 km/h at this altitude and M is the Mach number);EET-APT/STA-NASA: Fleet of Supersonic Transport Aircraft-NASA High-Speed Civil Transport (STA-NASA) beyond the year 2030 operating at a cruising speed of 2.0–2.4M at altitudes of 60,000 ft (1M = 1062 km/h at this altitude); andEET-APT/ECH-M5C: Fleet of EC Hydrogen-Mach 5 Cruiser (A2ECH-M5C) beyond the year 2030 with a cruising speed of 5.0M at altitudes of 60,000 ft (1M = 1062 km/h at this altitude) (Coen 2011; EC 2008; NAS 2001).
