Yes, I saw it on Airliners.net! That scheme is a bit past my skill level...I really like it, though!

This one maybe, but not sure about the ice blue nacelles, tho!

from the top to the bottom:
1) I can't remember which airplane is this used on...

2) 737-100/-200 JT-8D low bypass ratio turbo jet bucket type reverser.

3) 737-400/500 CFM56-3 and 737-600/-700/-800/-900 CFM56-7B high bypass ratio engine uses the cascade type reverser. (Just about all modern high-bypass ratio engines uses this type of reverser.)

Reverser type number one was used on the old, old school DC-8 series. Pictured is an Eastern DC-8-21.

Don't tell me that you guys will do Thrust Reversers on my 737.

I've gone too far to try that now but when you've got the "New Jet" ready I'll try it on that

On top of all this, then I ended up with 4 job offers before I even had gone to examination of my bachelors project(Thesis):-)

I am now employed in a company that will send me to Ming-land in the near future if I want to.

Ok ok guys, I am probably the biggest fan (no pun intended) of the amzing innovation and ingenuity shown on this thread but "thrust reversers" on an EDF?? Can someone look into whether this is a viable concept? You would have to slam the throttle right in to full on landing to get enough reverse thrust through the louvers or clams at a stage of the flight where battery power is most likely quite low and even then I seriously doubt an effective braking effect on the airframe beyond the natural slowing from friction of the gear and the dirty config she will inevitably be in, if anything I think the drag created by the opened clams, doors or louvers might have more of an effect than reversed thrust....am I wrong, please show me if this is proven.

I think the biggest value in a thrust reverser system on this bird would be scale detail value but is that worth the additional weight penalties?? Just my thoughts, what do the experts say?

In response to my own response to your ideas about reversing I found this....interesting - http://www.rcpowers.com/community/th...e-thrust.3590/

This is even more interesting - http://www.rcgroups.com/forums/showthread.php?t=1536251
