ZZZ Name Change for Sun-N-Fun?
on 4/20/2008 3:04 PM Ron Wanttaja said the following:
In my opinion, Zoom doesn't refer specifically to Sun N Fun for the same reason he only refers to Oysterhouse as "That nut from Oregon." A rare slip into journalistic accuracy??? :-) |

Until you find out what RRL's definition of a "race" is, I wouldn't place any bets. I guess I just assumed that everyone would agree with me that an exhibition is not a race. But for those in doubt, I meant a real Rocket Racing League event with multiple rockets competing. Your right a exhibition is not a race . I think a better race would be to take bets and see if the new fat zoomy can fit in the cockpit .Last I saw him he was quite pudgy :-) Chuck (20 # less )S RAH-14/1 ret |

snipped Three more exhibition races will be held at
Reno (September 10-14), at the X-Prize Cup (Las Cruces, NM, date TBA), and at Aviation Nation, Nellis Air Force Base (November 8-9). They'd better use caution at Reno. Frankly, they should cancel. Much too turbulence there with the Sierra Wave activity going on. Then there's the Dust Devils (Whirlwind, Zephyr). Tore one of the smaller IF1s apart when the aircraft inadvertantly flew through one; pilot killed. That aircraft was composite, roughly 1/2 the size of a Velocity. Brent Hisey had an Emergency in his North American P-51D Miss America, "Race 11," and the winds blew him away from the runway and into the sage at the last moment. Aircraft should have been totalled but Hisey rebuilt it anyway. He walked away reportedly covered in hyrdraulic fluid. Imagine what that Sierra Wave turbulence can do to a short-wing "glider" like the RRL Velocity. Rocket power is reportedly only going to be used in the ascent phase, so how is it "Rocket Racing" when power is "off" during the competition phase. Speed in the climb only 300 mph...I'll take the 500 mph range Unlimiteds any day. Three men killed at Reno in 2007, then a fourth after the races. That event not too big on safety and the (mis-) management is the reason why. A number of pilots retired after last year's event and either sold their racers or put them on the selling block, particularly after the accidents. If the weather at Reno isn't good, you could see the entire cancellation of the event, which could irk those paying for the tickets. I saw one of the Velocity prototypes at Mojave about two weeks ago. Appeared to feature a single seat with enough room even for a large man. Even Baby Huey (Zoom) could fit in that thing. (Did not observe a seat over on the "co-pilot's side. The way they're advertising the test pilot versions, these look like single seat racers.) As a side note to Mojave, the Rotary Rocket's move to San Diego was cancelled and it will now be on display at Mojave Spaceport next to BAE Systems, about a block away from Flight Ops. They set up a nice park and walkway there, so hopefully more displays will be added. The F-4 Phantom that was on display in front of Flight Ops is gone...perhaps in a hangar being restored? The Convair 990 Galileo II, from NASA, is now on gate guard at the front of the airport. Has been for a few years now. The number of airliners parked there starting to dwindle. |

Did find this picture on the RRL site, which is a real howler: http://www.rocketracingleague.com/ga.../runwaybig.jpg Note how the runway is just two wingspans wide, and the grandstands are RIGHT at the runway edge. We're finally seeing the results of Campbell's input. :-) Each race (again, according to Wikipedia) is supposed to last 90 minutes, with the planes carrying four minutes of fuel. World record for a rocket pit stop is something like three hours. Even if they get that down to 15 minutes (including the time to tow the plane to the fuel station and back to the runway), that's STILL a lot of gliding time. Ron Wanttaja It seems to me using solid fuel rocket engines would make more sense for racing. Each airplane would have two engines, one high impulse for take off and the other a long duration burn for the race. It seems to me rapid engine changes would be possible. I have always thought a replica Me163 with a solid fuel engine would be a rather nice air show draw. Dan, U.S. Air Force, retired |

So you lose a few spectators every so often when the pit goes boom, but that would only add to the excitement. Dan, U.S. Air Force, retired |

It seems to me rapid engine changes would be possible. It's an interesting idea, but has some technical drawbacks. A liquid rocket motor, like they're using now, gets fuel just like a recip: Fuel and oxidizer are stored in tanks and fed to the engine via pipes. It means that you can install the motor itself in the best location and put the fuel tanks on the CG so that the aircraft's balance doesn't change during. However, a solid rocket is a single, self-contained unit. If you put (for example) a Star 17A solid rocket where the Velocity's engine normally goes, there'll be ~280 pounds in the engine compartment when the motor lights off, but only ~30 pounds left when the motor burns out 20 seconds later. This is the equivalent of having a recip engine completely depart the airframe in flight. It's not insurmoutable...you could put a small water tank for ballast way up front and drain it at the required rate. If you could get five times the moment arm (which is probably pushing it) you'd only need a six gallon tank. But with both a boost and a sustainer engine, you'd have to have a larger tank with variable drain rates. And if the water drain system fails, the plane will shortly become uncontrollable...no way to shut down a solid rocket short of blowing it up. If your solid rocket motor were slim and long, you could install it so that half the casing was forward of the CG. But that does push it into the cabin. Due to the heat, I doubt a composite Velocity airframe could stand the motor near the actual CG. The only remaining solution would put twin engines on the wings. You'd have to beef up the wing structure to handle it. You'll also need to ensure the aircraft has enough rudder authority to handle it when one motor burns out a little earlier than the other. It would probably be a lot easier to mount a second liquid-fueled sustainer motor in the current vehicles. In fact, a better solution would be to install multiple small motors instead of the single large one they're doing now. This would give the pilots a "throttle" that would be a significant tactical factor in the event of an actual race. I have always thought a replica Me163 with a solid fuel engine would be a rather nice air show draw. The guys up in Everett manufacturing the Me-262s are building an ME-163. No plan to fly it, though. Pity.... Ron Wanttaja |
