In John Farley's lecture notes:
(John Farley's Lecture (http://www.harrier.org.uk/history/history_farley.htm))
In the 'STOL flying section' regarding slow approaches he states: 'There were two possible controls of lift (wing and engine) and two of speed (RPM and nozzle angle)...'
I have re-read this section and phrase many times and are struggling to get understanding regarding the meaning of 'engine' and 'RPM'. I am seeing them as interchangable and suspect I am wrong.
If they are interchangable, then they are a common factor and thus I read the phrase as 'wing controls lift and nozzle angle controls speed' and thus I am seeing only one control of lift and one control of speed - engine running of course.
Put me right someone.
Many thanks
Cron.
