China Challenges US in Supersonic Jet Race with Concorde-Surpassing C949
China is intensifying its competition with the United States in the aerospace sector, as its state-owned aircraft manufacturer, COMAC, has unveiled plans for a new supersonic jet. The Comac C949 is designed to fly faster and further than the retired Concorde, while also promising to be significantly quieter. This development places China firmly in the race to revive supersonic passenger flight, challenging American efforts in this high-speed aviation domain.
Comac C949: Faster, Further, Quieter Supersonic Travel
Aerodynamicists detailed the specifications of the Comac C949 in a recent research paper, as reported by the South China Morning Post. The jet is projected to travel at 1.6 times the speed of sound, exceeding Concorde’s speed and offering a 50 percent greater range. Engineers are focused on mitigating the disruptive sonic boom associated with supersonic flight. The C949 aims to reduce sonic booms to a perceived noise level of 83.9 PLdB, comparable to a standard hairdryer.
American Companies Join the Supersonic Race
While Comac progresses with its C949, it faces stiff competition from American entities. NASA and several US-based startups are also engaged in developing supersonic jets to fill the void left by the Anglo-French Concorde. These companies are striving to create aircraft capable of transatlantic flights in approximately three hours.
Spike Aerospace’s S-512 Supersonic Diplomat
Massachusetts-based Spike Aerospace is developing the S-512 Supersonic Diplomat jet. This Mach 1.6 aircraft is designed to have a range exceeding the C949 by 300 miles, presenting a direct challenge to the Chinese contender.
Boom Supersonic’s Overture and XB-1
Boom Supersonic, based in Denver, has achieved a milestone with a successful test flight of its Overture XB-1 prototype. The Overture XB-1 is designed to fly at Mach 1.7, slightly faster than its competitors, although its range is reported to be 4,888 miles.
Comac’s Ambitious Timeline and Space Ambitions
Comac anticipates the C949 to be operational by 2049, coinciding with the centennial of the People’s Republic of China. The company’s ambitions extend beyond supersonic passenger jets. Comac is reportedly exploring the development of ‘space-air hybrid vehicles,’ venturing into both aerospace and space travel. This broader scope could potentially heighten tensions with the US, particularly given the US Space Force’s emphasis on space as a critical domain for national security.
Concorde’s Legacy: A Benchmark for Supersonic Revival
Concorde, the pioneering supersonic airliner, remains a significant point of reference. Its inaugural non-stop transatlantic flight in 1973 was a landmark achievement. A flight from Washington D.C. to Paris took just three and a half hours on Concorde, a journey that contemporary Boeing aircraft require more than twice as long to complete.
The Concorde, a sleek, 203-foot aircraft, consumed substantial fuel to achieve its cruising velocity of Mach 2, or 1,350 mph. Only 20 of these 100-seater planes were manufactured over 15 years, signifying their complexity and exclusivity.
However, the Concorde era ended following a tragic crash in July 2000 and subsequent economic and security concerns after the 9/11 attacks, leading to its retirement in 2003.
The New Supersonic Race Heats Up
Aircraft manufacturers are now intensely focused on creating Concorde’s successor. Boom Supersonic’s CEO, Blake Scholl, acknowledged the intensifying competition with China, effectively declaring a new aerospace race. He emphasized the importance of surpassing the emerging Chinese supersonic capabilities.
Boom Supersonic’s XB-1 Test Flight Success
Boom Supersonic’s XB-1 demonstrator aircraft achieved a successful test flight earlier this year, reaching 850 mph and breaking the sound barrier multiple times without generating significant sonic booms on the ground. Scholl highlighted this test flight as validation that supersonic flight can be economically viable, environmentally sustainable, and passenger-friendly.
The XB-1, while designed for testing, provides a foundation for the larger Overture airliner, which is planned to carry 64 to 80 passengers and reach speeds of Mach 1.7.
Boom Supersonic has already garnered substantial commercial interest, securing 130 orders and pre-orders for its Overture aircraft from major airlines including American Airlines, United Airlines, and Japan Airlines.
Spike Aerospace’s S-512: Targeting Luxury and Range
Spike Aerospace remains a strong competitor in the supersonic field with its S-512 Supersonic Diplomat jet. This aircraft is projected to match the C949’s speed at Mach 1.6 but offer a longer range of 7,100 miles. This range would enable flights like New York to London in approximately 3.3 hours.
Beyond range, the S-512 emphasizes passenger experience, featuring a luxurious cabin designed for up to 18 passengers. Spike Aerospace promotes the S-512’s ‘ultimate comfort,’ highlighting features like fully-reclining seats, panoramic windows, and a noise-cancelling interior.
C949 vs. S-512: Range and Capacity Considerations
While the S-512 boasts the longest projected range among these new supersonic jets, the Comac C949 presents a substantial challenge. The C949 is expected to match the S-512’s speed and significantly exceed Concorde’s passenger capacity, accommodating 168 passengers. With a projected range of 6,800 miles, the C949 could potentially facilitate non-stop flights from locations like Britain to Malaysia.
The C949’s design incorporates an innovative fuselage with a ‘reverse-camber’ midsection. Engineers claim this feature helps to weaken shock waves and reduce sonic boom intensity, aiming to overcome regulatory restrictions on overland supersonic flight.
Regulatory Hurdles and Geopolitical Context
By minimizing sonic booms, developers hope to navigate and potentially circumvent regulatory barriers that have restricted supersonic flights over land. Comac, established by the Chinese government in 2008, currently faces US government sanctions due to its ties to Beijing, adding a geopolitical dimension to this aerospace race.
