God 10 return cabin to land to push engine: instead? Fan of Qian snipe Peng conceives?0 millisecond

Xinhua net Shanghai on June 26 report (reporter Zhang Jiansong) 3 spacefarers take divine boat to return cabin 10 numbers, return the earth to flood district of all over the sky from aerospace " last meters " , push engine to bear thewatch case manufacturer weight of instead by 4 when return cabin bottom amortize. To ensure safety lands, the group of institute of technology of Shanghai spaceflight motivation is dedicated developed 10 years.

In place of Shanghai spaceflight motivation, the reporter saw the prototype that lands to turn engine instead only. Of this small and exquisite push engine to have 11 kilograms only instead, look those who resemble a sousaphone " hat " . "Hat " go up fuel of upright fill solid, installation is returning the chair lower part of cabin spacefarer; "Hat " the lower end is concentrated beehive shape alveolus. Returnthe most popular watch casesing condition normthe most popular north face shirtsally, return cabin to be apart from the ignition when the ground makes an appointment with a meter of height, generation reachs amortize action since thrust instead.

"Return cabin touchdown instant to want to get very big concussion load, the amortize action that relies on parachute only is very insufficient still, the experiment shows the cervical vertebra that may bring about a spacefarer gets hurt, the safety of before because this need turns engine instead,undertaking touchdown last pace is ensured. " Yang Wei of assistant director of institute of Shanghai spaceflight motivation's researcher says, "The build that does not see this turn engine instead only is small, 3 tons can arise when ignition up thrust. When returning cabin to land, 4 produce 12 tons in all up thrust, offsetted much returns the kinetic energy of cabin, achieve deceleratwatch case openere goal thereby, assure to return cabin firm quietly to descend in the ground. Assure to return cabin firm quietly to descend in the ground..

Ideal amortize effect is when should pushing engine flameout instead, as it happens is the be born hour that returns cabin. Accordingly, the technical difficult point that advances engine development instead depends on " accurate " and " synchronous " . "brass faucet aerator After receiving ignition to dictate, 4 push engine to must ignite inside 20 millisecond instead, the ignition error time between two engine does not exceed random 10 millisecond. " Introduction Yang Wei. north face shirts

Because turn over the major installation harrison hot spring dealthat turns engine,returning cabin inside, also asthe best selling north face shirtsk to safety performance extremely tall. The case temperature after igniting to prevent engine lifts and make lacquer layer brandish gives out harmful gas, harm spacefarer is healthy, development group course tackles key problem assiduously, use a kind of new-style coat; The connect of each welding line of engine housing, passed strict vacuum leak hunting.

Regard divine boat as the works finally engine on airship, land to push engine to be before ignition instead, experience even blast off shake, outer space is environment of high low temperature, long a variety of test such as vacthe most popular selling norton internet antivirusuum condition, to assure the oneself quality of engine, development group undertook iteration experiment and imitate test and verify to its.

"Make sure the spacefarer returns the earth from aerospace safety, by lots and lots of crucial link series connection rises, turning engine insteathe best selling modern dining chairsdharrison hot spring weather forecast is among them last annulus, anything but can fail to build a mound for want of one final basket of earth-fall short of success for lack of a final effort. " Yang Wei says, "Place of Shanghai spaceflight motivation since since receiving the job 1993, technical program is adjusted for many times, development group hour carries responsibility in humeral head, put fame and gain in back, without last meters of path that blames the ground that do not have regret to come home for safety of spaceflight hero laid. Without last meters of path that blames the ground that do not have regret to come home for safety of spaceflight hero laid..
