I would like to apologize for my impossible rocket concept (https://iboman2.blogspot.com/2025/07/rocket-concept.html). It had several flaws. The major one being the wind turbine on its nose. The air taken from the inlet would immediately freeze inside at cryogenic temperatures and provide no pressure over the propellent. Coupled with the considerable drag of the turbine. The idea would not work.
However, it is still possible to burn a lot of fuel less efficiently and achieve some results when The Real Rocket technology is not available by a country. The propellent tanks need to be pressurized as they get empty. Helium is used for this task. However, it is very expensive and hard to source. Hydrogen gas maybe used instead. Hydrogen's boiling point is well below the propellants used on the rocket. A proper sponge like insulator should be placed between the pressurizing gas and the propellent to avoid any reaction between them.
At the end of the day, it's all about burning the fuel as efficiently as possible and fast to overcome the gravity. Direct lift off requires a lot of thrust. The airplanes utilize the lifting power of the air and take off with much less thrust. That's why in my very early rocket designs; I had proposed a giant plane to lift of the rocket's upper stages.
