Disney Launches Fireworks With Compressed Air

rtphokie writes "When Disney debuted its new firework show at Disneyland recently, they also debuted some new technology which uses compressed air to lift fireworks. This virtually eliminates the need for smoke-producing black powder and other materials at launch, significantly reducing ground-level smoke, and apparently: 'Disney is in the process of donating all seven patents associated with the new air launch technology to a non-profit organization so these patents can be licensed to other pyrotechnic providers'. Something to think about for those of us attending fireworks shows this weekend in the U.S."

      I know this is meant to be funny, but I would think anyone making a rocket propelled weapon wouldn't really care whether the propellent was black-powder based or air-based as long as it gets its payload to target.

      Actually, the U.S. military has a preference for non-flamable launch/propellent technologies because it's safer for the troops who're fireing the rockets. Basically a flamable propellant adds little or nothing to the damage to the target, but if the ammo store is hit, it adds quite a lot to the destruction of the ammo store.

      Strangly, not really true.

      Although fire is a big risk, you are all (hopefully) shooting with the same gear on as a low-budget fire department, so the odds of you catching on fire are pretty slim. The entire time you are shooting (if it's a hand-fire), you are being rained on by burning embers (barring good winds)

      It's the concussion of the charge that will get you. Whenever you are loading or handling fireworks, you always keep your back to an open area, so if something happens you get thrown away instead of thrown into something solid. The buildings that they build fireworks in will blow to pieces much easier than any normal building so that anyone inside doesn't get compressed by all that pesky expanding gas.

      I've only done around a dozen shoots, and am not a licenced pyrotechnician, but on two of the shoots we have had misfires. One was one of my tubes on a hand-fire, and fortunately blew out the other side of the rack (it was my first shoot). The second misfire was on a finale so everyone was quite a ways away, we didn't even really realize what happened until we were cleaning up and found a 2-by-4 twenty yards or so away and a half of a rack with a pretty much destroyed tube.

    One year when I was a kid, we got front row seating at a fireworks show where the launching was done from an island in a small lake. (The lake shore defined what was the "front row".) We were close enough to see the people on the ground, and the glow from the fuse as the firworks went up in the air.

    It rained on the day of the 4th, and apparently some of the powder in the launch tubes got wet. Quite a few of the fireworks went off at lower altitudes than intended. One particular launch went up about ten feet, came back down, lit on the ground of the launch site, paused a moment (during which the launch crew scattered), then went off on the ground. A couple seconds later, several more tubes launched. I don't know if the crew launched them, or the "extreme-low-altitude" firework did.

    Lets face it. Fireworks are nothing more than mortars with a slightly mistimed fuse and a non-fragmentary casing.

    Using any form of explosive to launch this is dangerous. The tubes must withstand the tremendous launch pressure. There is also the severe risk of burning ashes falling back into the cylinder complex and igniting a shell from the top down- at which point you have a buring bomb waiting for the heat to fry the launch charge.

    Modern shows alleviate nearly all of these problems... but I've still witnessed a number of accidents- the most memorable (for me) was when an ash fell into a mortar array atop the Citibank tower in Indianapolis- the entire rooftop 'lit up'. Someone was severely burned, and (I believe) lived... burned over a good portion of his body.

    Non-flammable launches won't eliminate (I'm going to miss the downwind smell, sigh) misfires in the tubes, but they should lower the risk during launch. It won't eliminate (or even affect) an ash falling into a shell, but at least you have less explosive contained in a small space waiting to go off.

    Just my opinion, of course.

Both are thin enough for the shell to fire through, and the combination of the 2 protects the shell from both rain and sparks. This protects against accidents at any time during or before the show, and the waterproofing means that it can even go off during rain.

    Rather, this surprise move by TDA is caused primarily with some hot water the Park has gotten in with the South Coast Air Quality Management District, or AQMD for short. Readers outside of Southern California may not be familiar with a government body like the AQMD, but they've been setting policy and regulating private enterprise in a successful attempt to reduce the amount of air pollution in Orange and Los Angeles counties for decades now. The Disneyland Resort is one of the 28,000 private businesses that operates with a permit from the AQMD, and is allowed a certain number of "pollution credits" each year. A business like Disneyland can earn credits by enrolling employees in clean air commuting plans that encourage Anaheim Cast Members to carpool, ride their bikes, or take the train to work. Disneyland Cast Members can earn a dollar per day each time they "Clean Air Commute", and Disneyland occasionally raises those stakes to three dollars per day and doles out the cash in paychecks or with gift certificates to Target or other big box retailers. While Disneyland earns credits with good citizen programs like those, it also loses credits by operating polluting engines such as on the Mark Twain or the parking lot trams. And as one of the biggest single site employers in Southern California with a huge physical plant of potential pollution sources, Disneyland often walks a fine line with the AQMD. Photo courtesy of Kevin Yee This regulatory environment that Disneyland operates in is what has led to a need to reduce the amount of smoke and pollution that the nightly fireworks displays pump into the air. Although the vocal group of Anaheim neighbors that got a decent amount of media attention last year with their constant complaints about the noisy and smoky Disneyland fireworks shows haven't helped matters, it's the more definable processes the AQMD uses to measure pollution that led to this situation. In fact, the AQMD's regulations are what led Disneyland to invest several million dollars into a new pneumatic air launching system installed just north of the park this past winter. It was hoped by TDA that this cleaner and less smoky process of launching fireworks into the air from a large block of modern launch tubes dubbed "The Black Forest" by Disneyland's pyro technicians would gain the park some leeway with the AQMD inspectors. Unfortunately however, while the new launch system was effective with the standard fireworks shells that shoot straight up, it left a great deal to be desired from an artistic standpoint with some of the more unique effects.

Some of these effects allow for timed designs - if the shell goes off right, you now have an expanding circle of "pixels" - so of you may have seen happy faces and hearts and similar designs done with shells. The microcontrollers can be programmed right before the launch to know when to explode (time or altitude based). I wouldn't be surprised if they don't have RF-based (hopefully over a secure encrypted channel) detonation. Perhaps even in-flight reconfiguration?

    Fireworks have recently become really high-tech, thanks to virtually throwaway low-power microcontrollers which are small and easily integratable into the shell.

    "We're a multi-billion dollar conglomerate buying up controlling interest in virtually every market."

    "Watch 'Home on the Range,' a movie about small time businessmen getting ground under by the heel of evil corporations."

    "We oppose the flow of information and ideas through copyrights expiring. 75 years isn't long enough!"

    "We just made some revolutionary technology. Here, have it for free."

    What corporate schizophrenia is going on here?

  53. This is nothing new.... by FuegoFuerte · · Score: 2, Informative

    Disney has been using this launch method for their fireworks for years. I remember visiting disneyland in elementary school (10+ years ago) and reading about their launch method, and this is the same system they were using then. Unique, yes. Kinda cool, yes. Possibly easier to choreograph than traditional BP-launched fireworks also. But still, nothing terribly new.

  55. Terrific News... now, get rid of the shells too by SubtleNuance · · Score: 2, Insightful

    This is a wonderfull development. Seeing as what a massive source of pollution Fireworks are. The blackpowder used to launch the shells will no longer release carcinogenic sulfur-coal compounds into the air directly ONTOP of our population centers.

    Everytime you watch a fireworks display, you are watching tonnes of heavy-metal and radioactive materials being peppered on your community. Making the evening not as wonderfull as Id like.

    But, tell me, how is a prudent environmentalist to come out against fireworks? What will the public think about the environmentalists who want to take something generally considered joyfull and request its abolition?

    on a more practical note, people need to be aware... we are capable of putting *some* amount of 'pollution' into our environment, but a wise person would not want to see so much that it adversly affects our (and nature's) health. If everyone decided "yes, we will release x,y and z of quatities a,b and c for this display and instead will stop buying/making/behaving in manner T" The trouble is we are not near this level of organization/understanding in the will of the public. Like most environmental issues that the public is directly connected to (consumption) they dont A) care or B) recognize their very real contribution to our looming problems.

    So, who wants to martyr themeselves on the Anti-Fireworks Brigade?
