Final Report 1987- 1988

The request for proposal (RFP) of the NASA/USRA Advanced Design Program which governed the Horizon design concerned a hypersonic civilian transport (HSCT). This RFP was decided upon by all four of the HSCT design groups, a decision based on the NASA funded HSCT studies conducted by McDonnell Douglas and Boeing Aircraft Companies. The vehicle's gross takeoff weight was to be less than one million pounds and have a range of 6,500 nautical miles. It was to cruise at 100,000 feet at a speed between Mach 3 and Mach 6. The vehicle's performance was to allow it to operate from an 11,500 foot runway, constant with current metropolitan airport sizes, and carry between 200 and 250 passengers. FAR 25 states that fuel reserves be five percent of the total fuel on board, and as for noise, the ground overpressure of the HSCT aircraft must be less than one pound per square inch.

Not stated but implied in this RFP was a vehicle planform effects study. Horizon has a blended wing-body. The joined wing, oblique wing, and caret planforms were considered by the other HSCT design groups.

Thanks for clearing the confusion! I've changed the topic's title accordingly.
