thanks a lot but i got to ask which of the air to air missile that have the best maneuverability ?
I am simplifying this quite a bit but a good rule of thumb is the size of a control surface will matter in that the larger the surface for a given speed will have more turning force applied and give better manouver capability.
An exception of course is when the control surface stalls... the front control surfaces of the R-27 where is starts out narrow and gets wider is designed to reduce drag and delay stall to give better turn performance than a standard triangular fin.
The potatoe masher type rear fins on the R-77 are also designed to give max turning force with a compact shape and high angles of attack before stalling.
the thrust vector engine gives excellent manouver capability, but only while the rocket motor is burning... just like aircraft a TVC missile has excellent turning ability.
the R-73 is smaller and lighter and has TVC so it can turn harder than the R-27.
The R-27ET has much longer range and a wider field of view because the missile body is wider.
If you were chasing down a target at low level the R-27 would have a better chance of running it down... otherwise the R-73 would be the preferred weapon... both don't just tail chase... they track the target and fly an intercept course to meet the target at a location ahead of where the target is at that time.
Makes them quite hard to evade.
(47kg warhead in the R-27 acts like a 4.2 ton mass at 90gs) WOW , i need to learn this info too or the equation .
Sorry... bad choice of words... everything has mass and mass does not change under acceleration due to another mass or movement.
the 47kg warhead weighs 47kgs at one g... ie sitting on a table. At 1 g its weight is 47kgs.
At 2gs its weight is 96kgs... its weight at 90gs is just 90 x 47kgs = 4,230kgs.
Its mass does not change... think of weigh as momentum, where speed is measured in gs.
