Lockheed CL-823 S.S.T. proposal
Projected by the California division of Lockheed, the CL-823 is the most akin to the Concorde of the three proposals. It has a comparatively narrow delta wing, although there is a reduction of sweep-back on the outer section to give a compound or double-delta effect not unlike that of the SAAB-35 Draken.
The CL-823 is designed to cruise at Mach 3.0 and is the fastest of the trio. It will carry 218 passengers and have a gross weight of 450,000 lb. (204,117 kg). Span will be 116 ft. (35.0 m), length 222 ft. (67.6 m) and height 49 ft. (14.9 m). Like the Concorde, the CL-823 would have a hinged nose section to permit improved forward view on the approach when the aircraft is at a high angle of attack.
Boeing 733 S.S.T. proposal
This type number has been used by Boeing to cover more than 500 designs which have been studied since the Company began its research into large supersonic aircraft about 1955. The Boeing 733 as submitted to the F.A.A. makes use of variable wing sweep-back to provide acceptable low-speed handling characteristics as well as the required high-speed cruise. When fully forward, the wing has a 20' sweep-back on the leading edge, and this increases to approximately 60 for the supersonic cruise.
One attraction of the variable sweep configuration is that it provides 'conventional' characteristics for approach and landing, whereas most delta-winged aircraft approach at a very high angle of incidence. Boeing already has completed an enormous amount of development on variable sweep wings, particularly for its unsuccessful TFX proposal, although much credit for the original concept goes to Dr. Barnes Wallis and his research team at British Aircraft Corporation. It will be ironic if the BAC-Sud Concorde finds itself in competition with an aeroplane which thus owes not a little to a BAC engineer.
Boeing has submitted plans for a basic SST (Model 733-197) and two alternative long-fuselage designs, one for U.S. domestic operations and a long-range intercontinental version. All would cruise at Mach 2.7 (1,800 m.p.h.-2880 km/h). The span is 173 ft. 4 in. (52.6 m) spread and 86 ft. 4 in. (23.2 m) fully swept, while the wing area, spread, is 4,684 sq. ft. (435.2 m'). Length is 203 ft. 10 in. (62.12 m) basic or 248 ft. 10 in. (75.84 m) and the height is 48 ft. 4 in. 04.6 m). The - basic aeroplane seats 150 passengers, weighs 430,000 lb. (194,790 kg), has a range of 4,030 miles (6,448 km) and takes off in 6,000 ft. (1,830 m).
The long-fuselage Boeing 733 carries 214-227 passengers. The domestic version weighs 408,000 lb. (185,066 kg) and takes off in 5,400 ft. (1,646 m) while the inter-continental version is projected at a gross weight of 520,000 lb. (235,868 kg) and would take off in 7,000ft. (2,134 m.).
