The plane could travel from New York to London in less than two hours, and could operate on commercial and military flights
In a glimpse of what could be the future of the aircraft. aviation, Boeing introduced the first concept of your hypersonic aircraft. The model would be able to travel from New York to London in less than two hours
The design was revealed at a conference at the American Institute of Aeronautics Aviation 2018, held in the city of 39; Atlanta.
Visually and technologically The aircraft, which could be used for military and commercial purposes, has much in common with a unmanned hypersonic surveillance and reconnaissance concept that the company revealed in January.
The two share the general configuration of the hang glider with two rear wings, an aerodynamic fuselage and a pointed nose. The ship would go to Mach 5, which would allow it to cross the Atlantic Ocean in two hours and the Pacific in three.
"We decided on the Mach 5 version," explains Bowcutt, Boeing technician and hypersonic scientist. noting that the Mach 5 exceedance, about 6,200 kilometers at the time, requires much more sophisticated engines and materials.
"This aircraft will allow you to fly over the ocean and come back in a day, which is the most people would like So, why exceed these limits and complicate it? The world is not big enough to go much faster than Mach 5 ", he said.
A Mach 5 aircraft can also be built more economically than an airplane using Mach 6, 7 or 8 because it would use readily available titanium. for its structure instead of materials such as composite ceramics to handle the heat produced at higher speeds.
Boeing's current proposal would also use a relatively simple pairing of a reactor and a ramjet engine, called a turbojet engine, in
For this aircraft, the two engines would share the same outlets. air, and the jet engines would run up to Mach 2 or 3 before the entrances sealed the planes. jet engine and deflect the air towards the ramjets, which can handle faster airflow.
The famous SR-71 Blackbird reconnaissance aircraft used this system in the 1960s, as multiple missiles and experimental aircraft. Boeing collaborates with Northrop Grumman Innovation Systems on engine technology
Although Boeing has not decided on final dimensions, the aircraft (which still has no name) would be larger than A commercial airplane, but smaller than a 737, says Bowcutt, it probably has a capacity of between 20 and 100 passengers
The feeling of force "G" at takeoff would last 12 full minutes when the # 39; plane will reach cruising speed (in a conventional plane the the sensation only lasts a few seconds) but the experience of the cruise should be serene, with an unobstructed view of the curvature of the earth at l. horizon and the darkness of the space above
"In addition, you would weigh a little less." said Bowcutt. "At this point you will have a few pounds less than on the floor."
Boeing says that a production aircraft with these capabilities, including autonomous pilotage, could evolve into 20 or 30 However, the fastest commercial flight to date has been made by the Concorde, with a Mach 2.02 speed, but these flights were canceled due to their high cost, embarrassment generated by the supersonic explosion, and an accident in 2000, where all the passengers died.
Scientists have pointed out that to have faster and faster planes more powerful engines and lightweight materials are needed to improve the aerodynamics of the fuselage.
