R-77 (RVV-AE) target G limit

[4c Hajduk Veljko]

"the R-77 (RVV-AE) can be used effectively for attacking tactical aircraft making evasive manouvres with up to 12 Gs ..."

 

Page 59, Soviet/Russian aircraft waepons since world war two by Yefim Gordon.

 

Our own Flaming Cliffs manuals states the same target G numbers for R-77 (page 136).

Hajduk.....throw that book away!

Here is a quote of the RVV-AE section - relevant passages highlighted in red:

РВВ-АЕ: ракета класса "воздух-воздух"

 

 

 

 

Впервые в мире на ракете класса "воздух-воздух" используются решетчатые рули с электрическим приводом.

 

Ракета обеспечивает поражение различных целей (высокоманевренных самолетов с перегрузкой до 9 g, крылатых ракет, ракет класса "поверхность-воздух" и "воздух-воздух", стратегических бомбардировщиков и вертолетов, включая поражение вертолетов в режиме зависания и другие цели) со всех направлений и ракурсов, днем и ночью, в простых и сложных метеоусловиях, при электронном противодействии, на фоне земной и водной поверхностей, по принципу "пустил-забыл", в том числе с многоканальным обстрелом.

 

 

основные характеристики:

• стартовая масса - 175 кг
  
• длина - 3,6 м
  
• диаметр - 0,2 м
  
• размах крыльев - 0,4 м
  
• размах рулей - 0,7 м
  
• высота поражаемых целей - 0,02-25 км
  
• перегрузка поражаемых целей - до 9 g
  
• дальность пуска: максимальная в переднюю полусферу -80 км минимальная в заднюю полусферу -0,3 км
  
• система наведения - инерциальная с радиокоррекцией + активное радиолокационное самонаведение
  
• тип боевой части - стержневая + мультикумулятивная
  
• масса боевой части - 22,5 кг
  
• взрывательное усройство - лазерный неконтактный датчик цели
  
• двигательная установка - однорежимный РДТТ

The Flaming Cliffs manual? :smartass:

Maybe one of them numbers is the seeker limit. Also, if I recall, when 12G is stated it's with a note "at short distances".

[Pilotasso]

This info is not very usefull since the missile lead all the turns in anticipation and, since the actual G limit of the missiles airframe is much higher than a fighter, and that the missile travels at very different speed ranges, from mach 4 to little faster than the fighter in the end game, the G load not only varies alot for the missile with speed, but also the G load required to hit the target could be entirely different from the one the fighter is doing.

 

A fighter doing 12 G's doesnt mean the missile is going to have to match that in pure porsuit. It could just cut the turn and hit it as easely as if it was flying straight, depending on the geometry of the fight.

Equaly a fighter that is flying straight could require de missile to perform a 30G turn to hit it.

 

So I dont think targets G is a very good measure for missile realibility. The seeker is often the weakest link.

 

Hajduk maybe you would like to diversify and upgrade your aviation library.

One other thing... it could be an export limit :)

That is the quote for RVV-AE which is the export version of the R-77. What about the info for R-77?

They are the same;)

What about a two mode rocket for the R-27E®(T)(P)?

Yup, that pretty much sums it up.

Thats a joke.......right? :)

[nscode]

something between a joke and spam :D

[4c Hajduk Veljko]

Please use this or open new thread (instead of R-27AE thread) to discuss details of R-77 missile.

 

Thanks,

 

BTW

 

Since R-77 can be used against AA missiles, the real question is if aircraft radars are able to detect (and track) incoming AA or SAM missile?

It's clear now;)
