Antipode hypersonic liner: from New York to London in 11 minutes

Renowned engineer and designer Charles Bombardier has developed the concept of a radically fast Antipode aircraft capable of reaching speeds of Mach 24 (28, 800 km / h). This will cover the distance from New York to London in 11 minutes.

Not so long ago, a Canadian engineer attracted public attention with another original concept of a bullet passenger liner called Skreemr, which reaches speeds of up to Mach 10 (12349 km / h).

As conceived by the creator, the plane was supposed to take off with the help of a railgun, which creates a powerful initial acceleration. Already in the air, liquid-propellant rocket engines are launched, which will maintain the gained speed throughout the entire flight.

Previous project from Bombardier - Screemr

However, two serious problems arose here - a powerful sound wave, as well as overheating of the wings and nose of the hull. Charles Bombardier turned to engineer Joseph Hazeltine for help, who suggested using a previously unknown aerodynamic phenomenon called "long-term penetration mode" to overcome them. As a result, the new Antipode concept was born.

Unlike the Skreemr, the new Antipode will be able to take off from a conventional airfield using reusable rocket boosters attached to the wings. With their help, the liner will rise to an altitude of over 12, 000 meters and pick up a speed of Mach 5 (over 6, 000 km / h). The spent boosters are detached and returned to the airfield, like a New Shepard rocket. After that, the on-board computer starts the hypersonic jet engine, accelerating the Antipode to Mach 24.

What is Prolonged Penetration Mode? To cool the body and reduce the level of the shock wave, it is proposed to use an air jet, which enters the nozzle in the bow at supersonic speed. The leading edge of the fenders can also be fitted with linear nozzles. Thus, all surfaces subject to overheating can be cooled to a safe level.

The wings provide the liner with enough lift to take off from a 1830-meter runway. According to the calculations of the concept developer, the cost of Antipode will be about $ 150 million per plane. All the necessary technologies for its creation already exist.
