sir Oliver Napisano Januar 22, 2011 Share #534 Napisano Januar 22, 2011 Буран obratite paznju kako izgleda "motor" na Buranu 2:39 - samo se po tome i razlikuje spolja od Americke verzije satla http://buran.ru/ Nije samo to razlika. The orbiters and the launch vehicle Globaly the 2 shuttles have the same dimensions, mainly because Buran was made to be a counterpart of the STS Shuttle. But Buran is a little bit lighter than the STS orbiter (62 tons instead of 68 tons). The major difference is the rear of the shuttles, STS have 3 powerful engines SSME for the lift-off whereas Buran has no. This due to an important difference in the design process. Buran was only a payload of the Energia LV so its engines was only for the orbit trajectories. The STS Shuttle has powerful engines because they are used for the putting into orbit, but once there they are useless. This difference lead to another one, Buran needed a launch vehicle whereas the STS Shuttle is its own launcher. So the engines are on the Energia launcher. The scheme of Energia is nearly the same of STS. A central block (2nd stage) with strap on boosters on its side (1st stage). The 1st stage is made of 4 boosters which are burning fuel and oxygen instead of solid propellant. This is a major difference in design because liquid propellants are more powerful that solid (chemical), and the engines can be easily controlled (increase or decrease the power, or cutting off), so in case of emergency they can be cut-off and prevent the launcher from explosion. The dimensions of the launcher are nearly the same (the Energia's boosters are smaller), but because Energia uses liquid propellant it is more powerful than STS. The boosters of Energia are also reusable but they use a totally different scheme. Once they burn all their propellant they are ejected from Energia in pair (to avoid damaging the shuttle), then they are separated. A small parachute is deployed to them down, once the atmosphere is more dense a bigger one is deployed. Finally to slow down near touch down retro-rockets are turned on and landing gears are deployed to land them safe. For STS the boosters are ejected after 2 min burn. Then a parachute slow them down until they reach the Ocean where they sea land. Another big difference is that Buran was made to be fully automated or remote controlled, in flight and even in working in orbit (for manipulating payloads). This functionality lead to big differences in the development of the shuttle and the launcher. Link to comment Podeli na ovim sajtovima More sharing options...
