The concept continues to hold up.
In an autophagic rocket, the hull would be used as solid rocket fuel, in addition to other propellants carried on board. For this purpose, the hull material must be both strong enough and have sufficient combustibility. During the rocket's flight, the body is consumed, allowing for a reduction in mass as it travels and leaving no debris once the flight is completed. This advance would enable more efficient and environmentally friendly launches.
Thanks to these initial three tests, it was possible to improve the fuel supply system and test new fuel components, which proved their safety and efficiency. All necessary parameters were measured and recorded.For the fourth experiment, the engineering team used the same oxidizing agent that was used in the third experiment, as well as a bell-shaped nozzle, to keep the variables consistent in the new test. Additionally, engineers used a polymer fuel rod and a gas-oxygen mix for a starter.
As the starting fuel was supplied, a pressure of 4 atmospheres was recorded in the combustion chamber. The fuel supply pressure remained stable between 9 and 9.5 atm, and the starting fuel was turned off at 203 seconds .
