WHERE is the Boeing Sonic Cruiser?!
Mentour Now!・18 minutes read
Boeing's Sonic Cruiser and Convair 990 were innovative aircraft designed to meet the changing needs of the aviation industry, but both faced challenges and limited success. The Sonic Cruiser, meant to be faster and more efficient, was ultimately scrapped due to operational issues and airlines' preference for slower flights.
Insights
- Boeing's Sonic Cruiser project aimed to create a smaller, faster twin-jet aircraft utilizing composite materials for efficiency, reflecting a shift towards more efficient, faster aircraft in response to changing travel preferences.
- The Convair 990, although featuring innovative turbofan engines and anti-shock bodies to reduce wave drag, faced poor sales and performance issues, ultimately leading to its discontinuation despite entering service with American Airlines and Swiss Air.

Area Rule in Aircraft Design: Efficiency and Limitations
- Engineers find it useful to use the area rule when constructing complex structures like aircraft fuselages, especially for pressurized designs.
- The area rule dictates that the cross-section of an aircraft should smoothly increase and decrease from nose to tail to minimize wave drag, crucial for transonic and supersonic speeds.
- Aircraft designs, like the Convair F-102, incorporate a Coke-bottle shape where the fuselage meets the wing to adhere to the area rule.
- The Concorde, despite knowledge of the area rule, had a straight fuselage due to material limitations and high temperatures at Mach 2 speeds.
- Boeing's Sonic Cruiser aimed for Mach 0.98 cruising speed, utilizing composite materials and high-bypass turbofan engines for efficiency.
- The Sonic Cruiser project was ultimately scrapped due to airlines' preference for slower, more efficient flights, operational complexities, and the post-9/11 aviation landscape.
