Mr. Bezos rocket company "Blue Origin" succeeded in passenger escape test, civil rocket to spare SpaceX
October 5, 2016, the rocket venture founded by Amazon's Bezos "Blue Origin"Successfully tested the actual passenger escape system, which is important in the safe launch of the rocket. The motion picture containing the test situation contains a state in which the upper occupant capsule ejects a rocket booster engine for escape from the rocket booster which is launched from the launch pad and rises and leaves.
Blue Origin | New Shepard In-flight Escape Test
The objective of this experiment is to ensure that the occupant safety system works properly by separating the occupant capsule from the rocket booster which mounts a large amount of fuel when some kind of abnormality occurs in the rocket during launch To confirm that you do. Actually launched the Blue Origin rocket "New Shepard" with the capsule for the occupant, and after 45 seconds, the capsule emergency escape booster is activated and moves away from the rocket booster at a tremendous speed is contained in the following digest movie .

Blue Origin's rocket "New Shepard" waiting for launch at the launch pad
A launch pad with a simple launch facility. A somewhat chunky New Shepard is a small rocket with a height of about 20 meters including capsules.
The capsule part attached to the tip. There is a space between the narrow booster and the pattern that the gas of the escape rocket injected at emergency escape passes through here.
A countdown took place, New Shepard's rocket engine was ignited ... ....
A liquid fuel engine with thrust of 110,000 pounds, horsepower equivalent of more than 1 million horsepower literally "blows fire" lift the capsule and booster at a stretch in the sky.
New Shepard keeps rising steadily while burning liquid hydrogen and liquid oxygen. Eventually, the moment when 45 seconds passed since the launch and the altitude reached 4893 meters ......
A blaze of fire is injected from the bottom of the capsule. This is the moment when the capsule emergency escape solid rocket booster was ignited.
By injecting a rocket booster with a thrust of 70,000 pounds for 2 seconds, the capsule is moved away from the booster and moved to a safe area.
In addition, the timing of this capsule separation is selected as the point of "MaxQ" which carries the maximum load on the aircraft. This is the moment when air resistance becomes the highest due to balance between machine speed and atmospheric pressure, it seems that it is the moment when it reaches the speed of sound at this altitude.
The capsule booster moves to the position deviating from the main booster's trajectory by controlling the direction of the propellant gas. By doing this, it is a way to avoid the influence of the main booster where abnormality occurred to the maximum, this was adopted also in the past Apollo plan etc.
Successful separation, the capsule stopped the booster had been falling free for a while ... ...
Three sub parachutes expand to control the fall speed.
After that, three main parachutes are deployed ......
It began to descend for a safe landing, spreading widely.
And 4 minutes and 15 seconds after launch, the moment of landing while finally raising the smoke. It is a moment when it is confirmed that a series of systems of getting out of the main booster and safely returning to the ground worked normally. By the way, at the moment of landing, it seems that rocket injection to ease shock was supposed to be done, but it can not be confirmed well from this picture.
And the camera to the falling main booster. It continued to rise even after separation and eventually rose to the point where it reached outer space of 93,000 thousand meters at the altitude. At the stage before the experiment, it was predicted that this booster would be destroyed because it was exposed to a heavy burden at the time of withdrawal of the capsule and could not be successfully returned, but as far as it sees, descent for landing without any problems It seems to be doing.
During the descent, the main booster controls the aircraft attitude by using the upper and lower fins while lowering the descending speed with the drag brake (air resistance brake) deployed on the upper part of the fuselage.
When the upper ground approaches, activate the rocket engine again ... ...
Perform a violent jet and suddenly lower the descent speed. If you look closely, the landing legs are deployed in the lower part of the aircraft. I can tell by watching movies, but I can see that it is descending at a tremendous speed until the moment of injection, and that deceleration G will reach 5 G at this time.
A little more to the ground. Drop with altitude and ...
Seven minutes and thirty seconds after the launch, I finally landed landing while raising the sand smoke. At this time, the descent speed of the aircraft has been dropped to just about 8 km / h, and it has become possible to landing a soft shock to the utmost.
The fire of the booster engine disappeared and the landing succeeded successfully. This time Blue Origin has successfully landed the fifth time, and it seems that this aircraft will be retired after finishing its role as an experimental aircraft.
It was a test scenery of Blue Origin that seemed to be perfectly "perfect success" that the capsule and the main booster succeeded in landing, overturning the prior expectation that "only the capsule will land".
After successful experiments, Mr. Bezos posted a tweet "Looking back on the unbelievable day, a toast to the wonderful 800 people full of passion for Blue Origin". By the way, the hash tag "#GradatimFerociter" attached to tweet is Blue Origin's motto "Gradatim Ferociter" based on Latin,Meaning of English"Step by step, ferociously" (step by step, fiercely).
In September 2016, Blue Origin says it has cleared a major step in future rocket developmentPublish future development planThen, a heavyweight reusable rocket "New GlennWe are announcing the development of. New Glenn is a heavyweight rocket with approximately the same scale as the Saturn V rocket used for the Apollo project, with a total length of 270 to 311 feet (about 80 to 95 meters) and a maximum diameter of 23 feet (about 7 meters) SpaceX heavyweight rocket "Falcon Heavy" suddenly surpassed, which is receiving the most attention in private space development. Furthermore, the 1st stage rocket is returnable to the ground after launch, it is possible to soft landing like New Shepard, it seems to have become a function of reusable rocket.
The movie at the beginning was a digest version of the test scenery, but in the following movies it is also possible to see the full length of over one hour.
