Distance a bomb can glide..

[Kaktus29]

..if designed to glide? ..what is the equation to get the distance? ..obviously it has to do with initial altitude, speed, and gliding characteristics of the bomb(aerodynamic shape, wings, probably sweep wings to increase lift as speed drops etc)..

 

so, if SR-71 or Mig-31 would drop a glide bomb while flying at 80-90.000 feet @Mach3 how far would a glide bomb fly?.. i'm thinking about 600-700 km?..am i way off?.. of course one needs calculations not "gut feeling" to know more precisely..

 

just extrapolating from glide bombs of today with a range of 60 miles already that are dropped from 30.000 feet @mach 0.9 ..

Have fun with that calculator. No gliding, just pure physics.

glide bombs are a whole class of their own. in testing an f-22 threw (not literally tossed) a SDB about 40kms away.

 

 

if you want to look at glide bombs:

It depends if you mean a glide bomb or a freefall bomb. If you mean a freefall bomb it is easy to get the distance, you must know only the altitude and IAS of the plane.

 

You will get the time of the freefall of the bomb from here: h=1/2g*t^2 where h is for height (altitude), g is a gravity constant (9,81 approx) and t is the time of the freefall. And when you know the time, calculating the travel in a horizontal plane is a piece of cake. It is s=v*t where s is a distance you want to know, v is a velocity of the plane and t is the time of the freefall. But the result will be only a theory, in real life you must also calculate with the airdrag, which affects the result very much at high speeds and it also limits the speed of the freefall. The result you will get is simplyfied and is valid only in vacuum :D

This solution also assumes that Earth is an infinite flat plane (like the Black Sea map). Sorry Eratosthenes.

Youre right, but the influence would be negligible in the comparison with the mentioned airdrag

Also it is incredibly dangerous to drop a bomb in supersonic flight anyway, I might add. I can't even imagine what problems might exist at Mach 3.

IRL, they do get rather squirrely at the supersonic/transonic region of flight and if you expected a clean separation at those speeds you would not even know what hit you as your aircraft starts to break up... Imagine that at Mach 3.
