1 Amateur Rocket Crashes, Another Explodes

prostoalex writes "A 23-foot-long space rocket carrying 3 dummies exploded in the Pacific Northwest after reaching about 200 feet. The team was competing for Ansari X Prize, offering $10 million to the team that successfully completes a low-budget private space rocket capable of carrying men into space. Google News offers more perspectives into the event, the team is saying the rocket, whose parachute malfunctioned, would have to be rebuilt." And AmiNTT writes "Everygeek's favorite rocketeers over at Armadillo Aerospace have suffered a fairly serious setback over the weekend - the crash of their 48-inch vehicle link in a test hop at their 100 acre test field. Of course there is video and pictures - 2 3... This setback should keep them from flying for about five weeks, but will give them a chance to make some design changes. I'm sure they will be back better than ever. (Armadillo have shown up on Slashdot many times in the past.)"

      Wow... am I with you on this one. Remember people... these are ENGINEERS. They are developing something new...

      Compare this engineering to software engineering.

      1) A software engineer comes up with an idea.

      2) A programmer writes a test case of the idea. Often, the programmer is the engineer in step 1.

      3) Software is run. Program crashes, bombs, but does something resembling the goals in step 1.

      4) Bugs are found, worked out, kinked, etc.

      Repeat steps 3 and 4 until the program works as it should....

      The ONLY difference between this and aeronautics is that when it crashes, you have to rebuild the rocket. (You have to rebuild the software, too, but that's assumed, automatic and usually done in 10 seconds)

      So, I really don't get why the disconnect. It's engineering! Products are seldom viable in the first design attempt, but a basically workable design is tweaked until it's ready.

      No different here.

      I'm concerned about Brian Feeney and his da Vinci Project. Apparently they may be planning to launch with no test flights in order to hit the deadline for the X Prize.

      This is extremely risky, and perhaps suicidal. Rockets do, as we've seen, notoriously tend to blow up and otherwise malfunction in their initial testing.

      NASA got it right because they tested over and over again and had a big budget to do so.

      With the deadline fast approaching, it seems that some teams, like Feeney's, will be tempted to cut corners in order to have a chance of winning the X Prize.

      Cutting corners and sticking to a timetable is what caused the Challenger disaster. I hope we don't see other lives lost as a result of this X Prize deadline.

    Good tests, Complete loss of vehicle

    August 8, 2004 notes

    Good Tests

    On Tuesday we did a very successful set of hover tests with the big vehicle. I had two changes that I wanted to test: an optional PWM of the throttle movement to make it change position slower when it was in hunt-for-an-acceleration mode, and testing a 50% gain increase which I might enable during high speed flights if it looks like it is having a hard time controlling the attitude. I had these set up momentary overrides on the joystick, so I could lift the vehicle up, engage the change, let go real fast if it isn't working, then try the other one, all on a single propellant load.

    When we tipped the vehicle up, several catalyst rings fell out of the engine nozzle. We looked up the engine with a boroscope and found that the screen at the bottom had pulled past one section of the support plate, allowing some rings to escape. This had also happened on the previous 12" engine after a few runs (you could see a couple red hot catalyst rings fly out in one of the static test videos). It didn't seem to be progressive last time, so we went ahead and left it alone, expecting the test run to squash the rings down into an interference fit again.

    Because this was set up to be a 25 second hover (tethered), which would be our longest hover test, we decided to make this a no-direct-view test, with my flying it from behind a concrete wall looking at a monitor instead of directly viewing it. The engine warmed up fine and lifted off and hovered fine. I was about to engage the first test when the vehicle just set itself back down on the ground. It took me a few moments to figure out what happened - I had moved the computer and wireless antenna behind the wall with me, so the telemetry link was very ratty, dropping quite a few packets. Eventually it dropped enough in a row to hit the internal limit and triggered a loss-of-telemetry abort, which is an auto land. Perfect!

    I moved the antenna back in view of the vehicle, and we completed both of the control system tests without incident. We used our new propellant disposal burner to catalyze the remaining propellant, which worked pretty well. The foam coming out was probably still 10% peroxide or so, but a little water was fine for washing it away. We might consider adding a spark ignition system to it so it would completely burn everything away, but that would be a more complex system, and would leave us with a red hot propellant burner.

    When we set the vehicle back down on the cradle, a few more catalyst rings came out, but the engine still seemed to be working perfectly.

    Based on these results, I changed the flight control code to use the PWM valve movement when it is hunting back and forth past a desired acceleration. If it hasn't crossed it in 500 msec, or the desired valve position is fully open or closed, it goes back to full speed.

    We also weighed the vehicle, and surprisingly found it lighter than we had estimated, right at 1000 pounds.

    Complete Loss of Vehicle

    Saturday was a perfect day for flying, so we went out to the 100 acres for a boosted hop. We had high expectations for success, since the vehicle had been operating perfectly on all tests so far.

    After we loaded up the propellant and pressurized the vehicle, we ran into a problem. When I opened it up to 20% throttle for the warmup it looked like it cleared up fine, but the telemetry was only reading 100C, as if the hot pack hadn't started heating. We were a long way from the vehicle, so we couldn't really tell what was going on. I gave it a bu

    Carmack commented on this on the Armadillo blog a month ago; his opinion is that only Rutan's team are close, given that they are very close to success he's not going to try a Hail Mary attempt, and nobody else is close as far as he can tell (and recent events would tend to underline this view). Furthermore, he and the rest of the Armadillo team intend to continue their rocketry work anyway.

    More broadly, I believe there are plans for post X-Prize competitions in the future, where various teams would get together annually to compete for the highest launch, fastest turnaround, and so on.

    Ultimately, it wouldn't surprise me, particularly if Scaled wins the X-Prize, if in a few years time we have the "Y-Prize" for orbital shots.

    I've noticed too many slashdot articles in which the information is misrepresented, misquoted, or quoted out of context. This is yet another case... Slashdot claims that it exploded after reaching 200 feet, which is untrue. It exploded 200 feet horizontally FROM its takeoff point. If you actually had bothered to read the article, the craft approached nearly 1000 ft vertically. It was during landing that the chute failed to deploy and the craft was destroyed.

    Of course, 1000 ft isn't that impressive. However, they did produce the craft very cheaply. And, it surely could have travelled farther than 1000 ft, they were merely testing their initial design.

    My advice for the team is to attempt to test their next rocket without their dummy payload. It would be best to successfully launch and land a test craft safely before attempting to gauge their capacity for load.
