Eggs in Spaaaaace!

I emerged Friday from the Basement Laboratory of Bumbling Brothers Flying Circus with a new G engine powered egglofter. Here it is next to the previous experiment:

G Eggloft Altitude May 2012

I, of course, have on my best "Steelie Eyed Missle Man" look.

The upper longer model is the new one. Its largest diameter is slightly smaller than the older model's largest diameter. Combine that with the single composite G40-7W engine having more total impulse than the cluster of 3 black powder E9-8 engines in the older model meant that it went to an altitude of 957 Meters compared to the 652 Meters of the shorter model. This was good for first place in the weekend regional contest.

The only problem was that the ejection charge, designed for larger diameter models, was powerful enough to burn through the shock cord. Fortunatly (through my Super Genius Design) the bright yellow egg and altimeter capsule was fluffy enough to tumble safely to the ground, egg unbroken.

Even with the first place, I feel it is possible to achieve higher altitudes. So it is back to the laboratory!
