Why does the hydraulic system need 2000 psi and the fueldraulic system only needs 50 psi?
Then they needed to double hydraulic pressure to 4000 psi for the new rocket, but never explained the key considerations. Seemed like it would be the same actuator?
Cool article.
- cvz 2y agoThe way the article describes that diagram is misleading. The whole diagram is the fueldraulic system, and it's 50 psi on the return side and 2000 psi on the high pressure side like a regular hydraulic system.

It was eventually scrapped because higher pressure meant the spray from a leak would slice up your skin. I think the Concorde went for the higher pressure anyway, but I'm not sure.
