TWR Issue?

[EVA_Reentry]

So, I took out an oversize book from the library on aviation. It had this entry on a German flying bomb prototype, which had an engine thrust of 948 kG/f, but could somehow lift off with a payload of 1945 kG. What?

 

As soon as I get back the book (I returned it) i will include a picture

The V-1 "flying bombs" were winged aircraft and so were perfectly able to fly with a TWR below 1.

Ah, I was just about to say something similar, but I had to read up on it on Wikipedia first to make sure I wasn't talking out of my, erm, bottom...

Oh, right! I forgot. Thanks y'all.

Airplanes regularly fly with T/W below 1. Way, way below 1.  The only planes whose T/W even approach 1 are usually jet fighters, and even that's not a given. The key is wings are far more efficient producers of lift than engines can ever hope to be.

Yes, only high performance jet fighters without much payload or external fuel has an TWR over one. 
Modern cruise missiles who are the modern version of V1 also has an TWR far below one, if not dropped from planes they uses an solid rocket as a first stage to get in air and get speed. more practical than the ramp they used for V1 and required as they launch with wings stowed.

The only plane that has a TWR > 1 I know of is the F-16, but then again I haven't researched many aircraft... But, basically what everyone else said. Wings provide most of the "thrust" but it goes down. Now, how they do that, on the other hand, is a much more complex story.

Also, the V-1's were launched on an incline.
Having wings still wouldn't have helped if the machine needed to take off vertically.

Well, Harrier has TWR > 1, because VTOL, which brings up an entire list of VTOL capable aircraft:

Also, every helicopter that has ever flown.

As for airliners, their TWR ranges from around 0,25 to roughly 0,30.

MiG-29, Su-27, Su-35 have T/W > 1

On afterburner, sure, but they don't necessarily need afterburner to take off.  Fighters tend to have a relatively high TWR (1) for combat maneuvers and (2) for supersonic flight
