Great to Hear Pilot Perspective
NW1...it's good to hear from you...your numbers fill in some blanks...How long did it take to reach cruise altitude...?...
Crabman...the inlet is not transferring the thrust force from the engine to the airframe...that's the job of the engine pylon...the inlet is actually making thrust...think it through logically...the engine adds momentum to the mass flow and hurls it out the back with greater force than it came in...the engine is hurled forward as a reaction...momentum is conserved...
Now why don't we put that same kind of nozzle on the front of the engine instead of a diffuser...?...the flow would likewise speed up increasing the momentum going INTO the engine...but what would happen...?...how would the engine react...?...if the flow going OUT is speeded up and the engine moves forward...then logically if the flow coming in is speeded up then the engine will move backwards...we get drag...not thrust...
That is why you don't see a nozzle on the front of the engine...so continuing in this logic...if the flow COMING IN is now slowed down...what happens...?...how does it all balance out...?...remember momentum must be conserved...where does it go...it can only be forward or back...there are no other choices...
