A mixture of 75% ethanol and 25% water was used, which was less volatile than pure alcohol and provided cooling through evaporation. The turbopumps, standing nearly two meters tall, were among the most advanced mechanical components of the era, spinning at over 3,000 RPM to maintain the immense pressure required for operation.
The V-2 rocket engine represents a pivotal moment in aerospace history, marking the first human-made object to achieve sub-orbital spaceflight. The precision of this guidance system was remarkable, considering the violent conditions of launch and supersonic flight.
