Thought I would share a couple photos of my latest project. This is being built hopefully for mach speeds and altitude. Fins are tapered and coated in 24-hour epoxy. They are epoxied to the motor tube and then the fin can is filled with epoxy foam.

I am using a Perfect Flite Stratologger as my altimeter as well as their idea to break the glass off Christmas lights and use them as electric matches. There is room for a siren in the AV Bay, but not much else.

The 6" AV bay has a 1" body tube segment that is glued in such a way that the forward end of the bay extends 3" away from the body tube, and the aft end is 2" away. I also extended of the motor tube to 5/8" past the bottom of the body tube. Finally, the eyebolts only have nuts on the inside sections of the AV bay. All these adjustments give me room to use a 38MM Cesaroni 6XL casing.

Any idea on alt ? Mach number?

Looks like something that id build.

The "lights" themselves, have you had much success with them? Id be petrified to rely on those espically for deployment, do people double them up for insurance? I would think that a basic estes fuse would be lighter and more reliable?

More pics comming I hope??

Thanks

I plotted in a weight of 27 oz. and a CD of 0.49 into Thurstcurve.org's algorithms and they suggest that the max speed and altitude will come out of a CTI J530. Altitude estimate is 9,809 feet, and speed is 1,828 feet/sec. which translates to 1,247 MPH. That is Mach 1.65.

I am going to go with the lights for recovery. In testing the system, they lit up instantaneously off a 9v battery when I vacuumed the air out of the av bay assembly. Next step is to make a couple charges with the lights and test them.

I love to fly little rockets with big engines. Think I was inspired as a kid when someone drove his Triumph Spitfire in my driveway. The itty bitty sportscar had a 396 Chevelle engine in it.

yeah.. nice... check this out.. Ive been in one.. After second gear, your jaw is dislocated, Just dont seem normal for a "ford"

a 5.0 liter in a little box.. add a bit of No2 and its not right....

Being a chevy man. Nothing beats a big block 427.... Nothing...cept for a hemi superbird..

I am going to go with the lights for recovery.

I did that, and then smashed the crap out of a rocket because one failed... buy some matches from Ken at the first launch. For testing I use a variety of things, but tests don't matter if the charge won't fire.

Any body tube reinforcement? Mach 1.5 is pretty fast......

The payload bay tube has a 1" section of coupler tube glued into it with a bulkhead then glued into the center. The lower tube with the fins glued to the side and the foam in the fin can should be OK. I saw a video of one going Mach 1.21 and the builder earned his level 2. I think making sure the fins are strong and stay attached is probably the most critical.

I ran some simulations in Open Rocket. Thought I would share them to see if anyone has any red flags.
