ECOF events - Kelly's Engineering Challenge 2011
Welcome to the Kelly Engineering Challenge for WOOSH ECOF 2011 ----- Legged Landers -----
This is looking to be a fun event. We have a lot of creative rocketeers. I think 2010 only scratched the surface! The preliminary rules for 2011 are... 1. Legged lander must fly at ECOF in 2011, under thrust of allowed propellant (BP, APCP, or hybrid). 2. The rocket, or a significant portion thereof, must land upright using folding, deployable landing legs. (i.e. the lunar module.) 3. Legs must be functional. (i.e. must support the landing weight of the lander and keep it upright on landing) Point deductions for a rocket that landed well but tipped over due to crosswinds will be at discretion of the judge. 4. Legs must fold or stow for boost, and feature some mechanism to deploy for landing. (Snitch's can fly, but with a full deduction of pre-flight judging points for innovation in design and degree of difficulty.) 5. Rocketeer must be certified to level of combined motors flown. NAR safety code applies. 6. Rocket does not have to be a crayon. Innovations in design are always encouraged. Family friendly theme mandatory. Remember the judge is a ten year old girl. 7. Scoring is as follows... 100 points total 20 points for innovation of design (theme, unique design features, including legs)8. Rewards... Points are cumulative. In addition to eternal bragging rights, the winner gets an engraved trophy, with medals for 2nd and 3rd place. All pre-registered participants get a nifty certificate suitable for framing. And, just as in 2010, the winner will receive a $50 gift certificate to Wildman Rocket Supply. dates - Saturday, 27 Aug 2011 and Sunday, 28 Aug 2011
