That sort of machine (ie a truck with a jet engine on the back) are generally used for two main purposes. Emergency clearing of snow on runways, and as a giant blast of decontamination liquids. In this case you have two facing towards each other but offset in a line so they don't spray each other. Then you get a column of armour to drive between them and get blasted from both sides to clean them. Very fast, very effective, very practical.Just when you thought you seen the last of the exotic Russians, pics like this one show up.
Any idea what the purpose of this machine is?
Also, when does MAKS2009 commence? (Dates)
Lots of airborne forces used in WWII managed to make it to the end of the war...In case of big war all VDV troops would be used in 1-2 days to make huge damage to foes in it rear or key positions.
All model Mi-24s can except the very latest models which have been upgraded using components and systems from the Mi-28. The new fixed models are lighter and while they generate more drag in a crash they also help absorb some of the impact.This might be a stupid question, but why some Mi-24 can retract their wheels while others not?
The Mi-24 generally and the Mi-14 have fully retractible undercarriage (except as I said the newest Mi-24s upgraded), while the Mi-8, Mi-17, and Mi-28 have fixed wheels.
Many aircraft with retractible undercarriage dont raise them if it is going to be a short flight or if they don't intend flying very fast. The reduction in drag is not much compared to the problems created if you have to land suddenly and forget to drop the wheels.
BTW a while back a vid was posted that had footage of weapons being fired from a train. If you look carefully it wasn't actually an armed train but a train with all sorts of armoured vehicles on the train set up so they could fire and operate from the train flatcars. One of the vehicles used was the BTR-40 with the twin 14.5mm guns for use in air defence and also ground fire suppression. It even had a tank on board. When there are no roads but there are tracks then it makes sense to do that.
