Lavochkin La 250 missiles and rails

[John R]

I'm just finishing an A Model 1/72 La 250 and the kit instructions for mounting the missiles on the rails seem to be at variance with the drawings in the Red Star book ' Heavy Interceptors'.

To get the missiles in the right place according to the drawings they need to mounted so far forward that the attachment point is right at the end of the missile body, which doesn't seem to be right for aerodynamic and balance reasons.

Is the kit rail in the wrong place? Are the drawings wrong? The photos I have seen are inconclusive.

Do the missiles have red noses as I have seen on some models. The kit says that they are white.

Can anyone please help?

Some British contemporary designs carried their heavy missiles on pylons that projected well forward of the wings, so it's plausible at least. There are some photos HERE that show the missiles carried underneath the wings, though they may well be test dummies as they're painted oddly.

EDIT: A better picture here: http://www.secretprojects.co.uk/forum/index.php/topic,933.msg7400.html

Again, the missiles are dummies, painted in that odd quartered black/white pattern.

This link worked but there were no pictures - only a few comments

The first link had some drawings that matched those in 'Soviet Heavy Interceptors' which appear to show the pylons much firther forward on the wing.Maybe they were moved at some stage in the development program. 04 didn't have radar and I believe only caried missiles for test purposes.

Ah, you have to be logged in to see pictures. It's worth signing up - it's a goldmine of information.

Here's the pic re-uploaded for you:

John,

 

K-15 missile ("275" project) has never went beyond ground testing, few pictures with b&w checkered missiles on "Anakonda" shows flight test dummies. So I assume that it's up to you how to paint a "live" rocket, unfortunately it will be "what if" anyway. My personal preference is red band on warhead

 

 

The mounting set-up you may see from the link below. It's a mock-up, but made by Lavochkin design buro. The missile has 3-point connection to the wing.

Thank you both for the quick replies and invaluable information. The problem now is where were the other two mounting points?

I'm quite happy with the black and white as my interest is prototypes and experimentals

Regards

John

John, if you checked the linked picture, other two points are visible: it's on a small sub-pilons (one is on wing leading edge, second is on the wing) attached to the rocket's wings

 

[John R]

I wondered if that might be the case but the photo didn't have enough detail to be sure.

Thank you

John

Not exactly an answer to your question, but just in case you haven't seen these photos:

Thanks Pin. I should have started this topic earlier as I have just finished it. However they could be a great help to someone else.

 

Dimitry - Ihave just mounted the missiles where your picture shows them and the missile fins line up nicely with the strange excrecences on the underside of the wings. I wondered what they were for.

"Strange excrecences" - it's exactly what I mentioned as "sub-pilons". Actually, those are small rails for rollers on tips of missile's wings. The most right picture in last row of Pin's wonderfull photo collection shows all three connection points in perspective. If you jump into links, provided by Pin, you find a nice close-up photo of those "rails/pilons"

Thanks to all who posted the links and photos. There is something wrong with model regarding the missiles and their mountings. Either the missiles are too small or the mountings are in the wrong place.

Here is a picture of the model as it stands. It has problems with the finish and with the attitude (too nose down). After all the problems getting it to this stage I am wondering if I am strong enough to deal with them...

Looks really cool, John! In my taste the finish is alright, dont see anything wrong with it. Nose down profile is also specific to this aircraft - it's visible on the pictures.

Thank you but you have not seen it close up!

Nose down profile is also specific to this aircraft - it's visible on the pictures.

According to the drawing I have in 'Soviet Heavy Interceptors' the fuselage datum is level but the drooping nose makes it look as if the a/c is nose down. If you you at the nosewheel the the angle of the assembly holding the wheel is not right. If that was corrected to match the photos I think the attitude would be OK.

Can you help with a question about the missiles. The kit missiles have a nose probe wheres those in the pictures, painted black and white, do not appear to have them. Is this correct?

K-15 missile went through several modifications (as well as carrier aircraft "250"), even changing it's propulsion type. One of the variants (K-15U) had some sort of nose probe or seeker head, very similar to the one you've built, but i haven't seen any photo evidence - drawings only.
