Aim-7 M

Funky Trees Guided Air-To-Air Missile

A longer-ranged BVR(Beyond Visual Range) option to my funky-trees guided Air-To-Air missiles. It is a 1:1 replica of the real thing and has realistic performance and stats, No part of the missile is guided/controlled by in-game default missiles nor gyros!.

History of the AIM-7, directly copied from Wikipedia
The AIM-7 Sparrow (Air Intercept Missile[5]) is an American medium-range semi-active radar homing air-to-air missile operated by the United States Air Force, United States Navy, United States Marine Corps, and various other air forces and navies. Sparrow and its derivatives were the West's principal beyond visual range (BVR) air-to-air missile from the late 1950s until the 1990s.
The most common version of the Sparrow today, the AIM-7M, entered service in 1982 and featured a new inverse monopulse seeker (matching the capabilities of Skyflash), active radar proximity fuse, digital controls, improved ECM resistance, and better low-altitude performance. It was used to good advantage in the 1991 Gulf War, where it scored many USAF air-to-air kills. Of 44 missiles fired, 30 (68.2%) hit their intended targets resulting in 24/26 (54.5%/59.1%) kills. 19 kills were obtained beyond visual range.

Player usage

Simply select an air target and BRIEFLY HOLD DOWN FireWeapons button (left alt on PC) and the missiles will fire one by one. No need to acquire lock and such.

Features and abilities

  • 1:1 replica of the Aim-7M missile
  • Not guided by default in game missile or gyro
  • Realistic performance as referenced to War Thunder
  • Uses a combination of Proportional Guidance and Inertial Guidance
  • Very long range, capable of BVR combat
  • Able to glide to target after fuel has been exhausted
  • Able to re-engage target if it misses the first time
  • Able to lock on after launch
  • Impervious to countermeasures
  • Gives no launch warning to targeted aircraft

Limitatons and problems

  • The missile's performance is highly dependent on the performance of the device, where a lower frame rate could dramatically lower the missile's performance
  • The missile has a slightly hard time orientating and tracking targets when it is pointing directly up or down
  • The smoke generator (a tiny hellfire missile inside the missile which it's sole purpose is to generate smoke for looks and provides no guidance or thrust) may sometimes fall out of the missile due to violent maneuvers or lag. This does not affect the performance of the missile whatsoever.
  • The missile is less maneuverable and slightly slower at higher altitudes (>30,000 ft)
  • The proximity fuse has a chance of not detonating due to physics limitations

States

Max speed: Mach 4
Maximum flight range: 50KM
G load: >30Gs
Rocket burn time: 4.5 seconds booster, 11 seconds sustainer
Track mode: Semi-Active-Radar-Homing (SARH)
Guidance time: 75 seconds
Weight: 509 lbs

Notes

This is a much better attempt at a replica of a real life missile (looking back at my Python 3 post lmao). I have recently figured out how to code proportional guidance and it is a lot simpler and shorter code although slightly less accurate, so I paired it with my tried and tested inertial guidance code. In my next projects I will not only be making a missile using proportional guidance, but also focus on the missile's adaptability as it would be cool if other people can easily mount and use my missiles on their machines as well. I am thinking about something like the AIM-9J/P variants or R-60 or even R-73 series (although then I would need to dabble in thrust vectoring technology)

If you would like me to mount these missile on your build, please contact me in the comments as it is still quite a process to do and so I would be happy to do it for you.

    @Lorenzexe I will be re-making this missile in the near future with an attached installation guide. However, if you must know now:

    1. Go inside the missiles, take the flight computer out, and save it as a sub assembly
    2. Take the entire missile (that now has no flight computer) with the pylon and save it as an sub assembly
    3. Copy all of the expressions and corresponding names in the variables menu and save it somewhere (for ex google docs)
    4. Go the the plane you intend to mount the missile on and mount the missiles
    5. Now mount the flight computers on the missile
    6. Copy in all the variables

    @Ku @Ku 说实话 我找到了一个更加方便的安装方法,那就是只留下飞行计算机和导弹 后将想要安装这个导弹的飞机去掉飞行计算机保存为子组件,再把那架保存为子组件的飞机拿出来和导弹组合就行了

    @j20m I'm going to assume you want a sub assembly version of the missile to mount on your own plane
    Unfortunatly making it a stand alone sub assembly is not going to make mounting the missile on your plane easier. Please reference my other missile where I have created detailed installation and set-up instructions (such as my Aim-9P).
    I can understand Chinese but I would prefer to communicate in english.

    I love this missle and i am triying to put it on my airplane but it doesn’t work. I can’t really make a subassembly and I don’t know why. do you have any tips?

    @SuperSuperTheSylph This problem is fixed from my Aim-9 P missiles and beyond where i came up with a better fuse code that would actually reliably self destruct the missile after it misses. This missile is not popular enough for me to re-release it with a new code just yet.

    @Ku can it be anyhow fixed?

    if you fire both of the missiles at the target and one splashes the target the other will go rogue and attack you

    @F8boa i am 90% sure I already know how to achieve what ur telling me with funky trees alone, however i am just busy with other projects right now but the idea is now on my radar and I will give it a shot one day.

    @F8boa if the default missile is directly attached to the missile shell and is then separated from the main flight computer/cockpit, then the flight properties would completely depend on the default missiles flight properties and would then be completely independent of the little engine, fins, drag, etc, which would then defeat the entire point of FT missiles.
