Using rockets can shorten international flight time

Private airlines are exploring the possibility of using rockets to transport passengers over long distances in less time than many commercial aircraft.

In early May, Australian airline Qantas announced plans for the world’s longest non-stop flight from Sydney to New York or London in 20 hours, due to start in 2025. However, according to research published a few weeks later by the British Civil Aviation Authority. , that trip could be shortened to 2 hours, or a tenth of Qantas’ flight time, if rockets were used.

According to the named approach rocket trip from one point to another, rockets can be used to launch spacecraft into suborbital flight, allowing travel at speeds of up to 6,437 km/h, according to David Doughty, CEO of Admiral Jet, a company specializing in private jets and helicopters. Today’s large commercial jets fly at approximately 885-965 km/h at cruising speed. So the speed of the rocket will make a big difference in the arrival time. “Rockets can change the way we think about travel and open up new opportunities for exploration and discovery.”said Ɗoughty.

Several space companies are investigating the technology needed to rocket travel from one point to another. Billionaires such as Richard Branson, Elon Musk and Jeff Bezos are joining the new space race through their respective companies Virgin Galactic, SpaceX and BlueOrigin. At the end of May, Virgin Galactic announced the successful completion of the fifth space flight, and commercial flights in space could begin from the beginning of June.

The US military is also working with SpaceX, Blue Origin and Rocket Lab to explore the possibility of moving rockets from one point to another to deliver cargo, according to Joe Cassady, an aerospace engineer who works for the ƝASA company. They’ve made great strides in developing reusable rockets, but there’s still a long way to go before they’re ready for commercial flight. Construction of the launch facility, establishment of the flight path and coordination of the air traffic control system will require significant capital investment as well as collaboration between the space company and the government.

Additionally, rockets use volatile fuels and explode in large quantities. Therefore, it is likely that the launch site could not be located in a convenient large city, but in a remote location such as SpaceX’s test site in Boca Chica, Texas, near the Mexican border. Finally, the industry must consider the impact on the environment, both on Earth and in space.

During launch and landing, passengers will experience G-forces, or large g-forces, according to Cassady. Astronauts now feel a G-force of 3, making the body weight 3 times heavier on the ground. Therefore, the seat must fit snugly to absorb some of the load.

Passengers will be required to wear pressurized space suits and helmets during the 10-minute takeoff and 40-minute landing. But for 30 to 60 minutes in orbit, they can feel a state of microgravity. They can take off their suits and float freely.
