Hello
Please help me, a physical relation which my friend is facing, I'm unable to get my head around..
I created a 2D S-duct, the contours are as follows
1.Static pressure
2.Velocity contours
3. Total pressure gradient graph
intake Velocity 20m/s
Guage pressure is taken as '0'...
Hi there,
i don't think u can obtain the design point just by predicting/from previous data from BPR and FPR, it should be an overall pressure ratio and TET as well for example take some X, X1 and X2 engines (all three should be either be turbo jet or turbofan, better try thrust levels not being...
Hi samsung90, even i wanted to do the same thing..Aerospace engineering and Cosmology..As Pengwuino Said its true One is an engineering field and one is a natural science.
but you have a option like if possible 1st complete Astronautics and then after that when u find job some where do it...
Hi Viscous Flow, and others What everything said was fine but I have a doubt like see For example as sweetiebyuty said when the pilot pulls the stick and hold in the same angle of attack then how can we say about its Negative pitching moment( I mean i do understand the pressure makes the...
'No' I have never come across a 4 spool engine, and yes it would be more complicated and causes lots of maintenance problems for a four spool engine, I would better suggest to discuss about a three spool or two spool engine in this thread.
Major advantage of triple spool design is it's ability...
A good reason that some aerofoils have negative pitching moment is that lift is concentrated on the forward of the aerofoil that is 1/4 of the chord region.

That is a very good question,
We actually try to calculate maximum lift of the aircraft or aerofoil to know the maximum lift is how far and the next point of the increase in the Angle of attack (AOA) causes downfall of the lift and increase in drag and tends to stall.
And when coming to L/D...
That's good, with nozzle designs your can estimate the fluid(Gases) flows out from the nozzle, velocities of the exhaust flow for different nozzle section and some designs on the thrust reversers as well at different nozzle section and how can thrust reversers be arranged with the appropriate...
GOOD, DONT GIVE UP. our sir said that In 2006 one of our senior built one jet engine it took him around 6 months to built, worked fine sound was horrible it seems
some links might be helpful to you
