How do manned balloons simulate space travel?

Although early scientists used manned balloons to carry out research work, they soon discovered that research work could also be completed by ground-controlled balloons. For the sake of cost and safety, most scientists control balloons on the ground to explore the atmosphere.

In the late 1950s, the military began to consider manned balloon flight. Military pilots need to know the problems that may be encountered when flying above 30 thousand meters. At that time, it was suggested that once the rocket was successfully launched, the manned space program could be carried out. The military should test high-altitude equipment such as parachutes, booster suits and life-support systems, and also want to know more about space medicine.

Both the navy and the air force have made plans for manned balloon flight training. The navy's plan is called "Stratosphere-Laboratory"1956165438+1October 8, and it was organized by naval officer Malcolm? Ross and m? Lee? Lewis's stratosphere-laboratory balloon 1 rose to a height of 22,800 meters, setting a new record. Although the falling speed of the balloon soared due to the failure of the air valve, the huge balloon finally slowed down and landed safely.

At the same time, the Air Force also began to implement a series of high-altitude balloon flight plans codenamed "Gao Man". Gao Man's capsule is a cylinder, and its size is closer to the small conical capsule of Mercury used by the first seven astronauts, rather than the balloon pod invented by the Picards, which looks like a large diving oxygen tank or submarine periscope. Only one person can be accommodated in the engine room. The driver wears a partial pressure suit and sits in a nylon seat with mesh, surrounded by life-sustaining equipment and scientific experimental instruments.

This polyethylene balloon is made by Wen Ren Research Co., Ltd. The capsule and parachute can be controlled by the pilot or the ground to leave the balloon and return to the ground. The capsule can also be equipped with a program to leave the balloon at dusk on the second day of flight.
