WebAnswer (1 of 10): I am very bad at formulas, so I will try to explain this in plain language. Jet engines have different power at different speeds. They have constant thrust. Here’s why: When the engine is stationary the ejected gases move relative to the earth with speed equal to the speed of...
WebThere was no significant change in the 400’s specification (compression ratio, camshaft profile and timing, etc.) from 1971 to 1972, yet the advertised power rating dropped by about 33%. That lower rating was entirely a result of switching from gross power to net power ratings, and that drop of about one-third is typical of most engines.
