Canadian Team To Launch X-Prize Attempt Oct. 2 211
FreeHeel writes "A second team of rocketeers competing for the $10 million Ansari X Prize, a contest for privately funded suborbital space flight, has officially announced the first launch date for its manned rocket. The da Vinci Project, led by Brian Feeney of Toronto, Ontario, said Thursday the group plans to loft its Wild Fire Mark VI spacecraft on Oct. 2, just days after the planned launch of another X Prize contender, the U.S-based SpaceShipOne. The balloon-launched Wild Fire event will be followed by a second launch within two weeks to snag the X Prize purse, according to the plan."

Is the SpaceShipOne team planning for a rapid turnaround (48hr? 72hr?) to try and grab the XPrize before DaVinci has a chance?
Burt Rutan has suggested that the second SS1 flight could be as early as October 4. (Note the historical significance of the date.) If so, then the only way da Vinci could win is if they have a very tight turnaround time: no more than about 48 hours. Given the October 2 Wild Fire flight will be its very first, that short of a turnaround time may be infeasible.

That's only relevant for, as you put it, "super high altitude dirigibles", because they have to be built so thin. The atmosphere, where Wild Fire is released (24.4 km) is hundreds of times more dense than the atmosphere at the altitude that the record setters go up to (40+km).
> since the big bomb strapped to the balloon is a much bigger concern
Wild Fire is a LOX/Kerosene rocket designed with a pretty impressive "simulate the heck out of everything first!" methodology. SpaceShipOne is an N2O/Polybutadiene hybrid rocket. While both involve pressurization (since neither use a turbopump), the pressurized substance in SpaceShipOne is much larger, and is the oxidizer itself (as opposed to a relatively small helium tank in the case of Wild Fire). Furthermore, with a gaseous oxidizer, the explosion would be a lot more violent. So, if I have to call one a "big bomb", I'd call SpaceShipOne the "big bomb".
In general, I really like Wild Fire a lot better. Higher starting altitude, a much higher ISP engine, and a very good design methodology.

Hybrid rocket motors are *simpler* than bipropellant rockets. That makes them less prone to *failure*, but it doesn't make their failures less catastrophic. The facts of the pressure in the tanks and the chemistry remain the same. N2O makes up the vast majority of the propellant mass in SpaceShipOne. I can't find exact stats on how much it's pressurized to, but it's not uncommon to find N2O rockets with pressures up to 50 atmospheres at launch (steadily decreasing thereafter). In short, the vast majority of the oxidizer is *incredibly pressurized*, and is *gasseous*. That's a perfect recipe for, should failure occur, *catastrophic failure*. If the nitrous tank were to rupture, it would easily slice open the polybutadiene. The notably increased surface area in the polybutadiene would dramatically increase the combustion rate (damaging it more), etc. In short, it would be a catastrophic failure.
In case you're not familiar, surface area is everything with solid fuels. You can select your thrust over time by the pattern that you cut into the center of the solid rocket booster (circle, star, etc). The reason that solid rocket boosters tend to fail catastrophicly is because when they're ruptured, their surface area increases, and the explosion takes off exponentially (as described above). While hybrid rocket motors don't have the oxidizer mixed in, the situation we're describing is a rupture of the oxidizer tank - and since the oxidizer is a pressurized gas, it will be all over the solid fuel and ready to combust.
On the other hand, getting a fast conflagration from LOX and kerosene isn't that simple. Have you ever tried to get a conflagration from gasoline? It's not that simple. You need proper mixing ratios and fine particle size of the gasoline. The same holds true here. The LOX won't vaporize instantly (unlike the N2O, which is already gaseous). The kerosene will vaporize even more slowly. It's not that likely to form a major conflagration before the capsule was ejected and out of range; and, unlike using a solid fuel, the explosion of a liquid/liquid biprop rocket tends to *disperse* the fuel and oxidizer, *slowing* the reaction.

You would, now would you?

The -only- problem with da Vinci over the year that I've been involved has been money. Now that we have some money, hopefully enough, the problem has suddenly become 'time'. Burt's team has set a tough schedule for us, but it's certainly not a foregone conclusion. We've done -tonnes- of design on this rocket, and now we have to take on a sort of skunkworks mentality to get it done. Contrary to what I've been reading today, we will be doing lots of component/subsystem level testing. The amount of integrated end-to-end testing will likely be limited simply due to time. This does NOT mean that the rocket will be fundamentally unsafe. There will be no launch unless it's determined that the pilot has a very high chance of survival.
With our design, there are very few inescapable scenarios. Our engine technology change was made long ago in part due to the added safety (I don't know why it hasn't been added to the website). Failure and loss of the vehicle may be likely (makes it more exciting to tune in on launch day), but there will only be an outside chance of anything morbid.
It's dangerous for this new industry to become obcessed with doing things like the rest of the space industry. Space projects cost a billion dollars because of paperwork and analysis, not because of hardware and software. At my day job, nothing is done unless there is essentially -no- credible chance of failure (loss of crew or loss of vehicle). Anything which could become a hazard to that extent has triply (or more) redundant systems (4 ways to drive the arm joints, etc.)
If my night job (da Vinci) took on that mentality, nothing would get done, and all we'd have is a pile of paper and empty toner cartridges. Take away some of the requirement for -complete- safety, and all of a sudden more gets done.
Anyway, I'm optimistic that we'll get things together pretty soon. We've got some high-profile tests on the books in the coming months. Should be exciting.
