Flight Log - 2011-10-08 - Rich DeAngelis's Ricochet

The Ricochet: The Ricochet is another design inspired by air defense missiles.  It has a reducer to a long, thin payload section.  It is an easy, modern kit. Instead of regular gloss, I used a metallic blue paint, and painted some silver rings around the tube heads, and clear coated the entire model after the decals were added. The payload section has vent holes for use with a barometric altimeter. I like this bird, it's tall but pretty light, and it travels pretty far on smaller motors. This rocket has flown higher than the Time Warner Center Towers in NY, and the Bell Atlantic Tower in Philadelphia. From sea-level it could have flown over the towers of the Golden Gate Bridge in San Francisco.

Flight Date: 2011-10-08
Rocket Name: Ricochet

Flyer's Name: Rich DeAngelis
Motors: B6-4
Launch Site: Penn Manor School Lancaster PA
Actual Altitude: 347.00 Feet

After the previous dismal flight I had to go to a rocket I can trust. The Ricochet was repaired from the last ejection snap-back damage and included a much longer shock cord this time and it worked very well. (Note: Double the length of any Estes shock cord. Trust me.) The rocket took off, burned for 8/10 second and generated 15.1Gs with this light rocket. It reached a top speed of 96 mph. Average acceleration for the flight was 5.4 Gs. After burn-out, the rocket coasted upwards for another 4.5 seconds and slowed considerably when the ejection fired at an altitude of 340 feet, stopping the rocket at 347 feet one half second later. After a well deployed chute, it descended at 6 mph, changing course abruptly as it fell through about 100 feet. After 40 seconds, the rocket was at rest in the grass nearby.

I learned another leson this day. As the rocket was all prepped and ready to go, my finger literally on the launch button, my fiance called and I answered it. About 20 minutes passed before I was again free to launch. I had to remove the rocket, open the payload to check that the altimeter was still on (battery save feature of course), re-pack the parachute sitting in the full sun and hook up the igniter wires again. Meanwhile a spider was building a web - on the launch tower, ignitor wires, everywhere! Thin silk sticking all over my hands. Moral: NEVER answer a cell phone before a launch. Wait 40 seconds and the flight will be over.
