Bomb Rocket

[David Schwantz]

3D printed NC and transition. The rest is LOC tube. Small tube is MMT. It will blow out and come down on a streamer and pull main out with it. Bomb will come down nose first.

I like it Sir!

On a humorous note: Imagine if the ejection charge fails and it nose dives into someone's front yard.

Looks really good.

Here is a picture of my take on a 500lb bomb. 35" long, 56 ounces. Body is 4" tube.

The length gives it a very arial torpedo look to me...

I like it. I've been thinking about using that fin design on a rocket, without the rest of the bomb look.
I was watching a show, the other day, about the problems they were having getting one of the atomic bombs, that they dropped on Japan, to stabilize. I think, what they came up with, was called the California parachute or something like that.

Very very cool! Really like the decals. Makes it look so authentic.

Sticker Shock.

Would hate to get pulled over on the way to a launch and have to explain something like that!

 

[David Schwantz]

H3ll, that's nothing. I built a 1/4 scale FW 190. Took it to the flying field and didn't even think about that swastika on the tail that was over 3' tall. Lucky I didn't get shot at.

Put a brightly colored chute on it, otherwise it’s gonna be a PITB to find in the weeds.

 

[David Schwantz]

Yuppers, gonna be neon orange from Top Flight. Streamer will be the same.

 

[Bat-mite]

Super creative!

 

[David Schwantz]

Thanks Bat.

How unusual!!!
A Bomb with a Parachute?
Unless it was a remote steerable chute, it will certainly drift off target!
This is just begging for rear ejection!
Nice Job Sir, I like it very much!
Have fun flying it.

I made something similar in 4" phenolic a few years back, but shorter. The square tail was a challenge to get right.
Mine had a red button on the end of the nose, so it was more iconic than real-life. Can't find the launch photo's, but here's the rocksim 3D rendering. Was painted light-medium grey.

Used a WW2-inspired pinup as logo, laser printed as a transparent sticker.

On another humorous note, take it to the Airport and give the TSA a "thrill" . . . LOL !

I have had no issues with a draggy square fincan on my 8" Fat Man build with the largest motor flown being an H225. Stability required half of the 3 lb rockets weight being in the nose. Rear ejection is a cool look on the way down.

SBR 5.5\

It\'s not a real bomb, but it looks like a WWII iron bomb - and it really flies! SBR\'s The Bomb is a 5.5\" diameter kit that includes SBR\'s new 5.5\" Airframe tubing, a 3D-Printed custom plastic nosecone, laser-cut plywood fins and centering rings, a 38mm motor mount, 45\"

www.fusionrocket.biz

Currently sold out but still a very nice looking kit.

Were the nose and transition pieces something you designed or found? I can't seem to find anything online. I've been wanting to do a smallish bomb rocket for our low power field. I'm assuming the fin pieces are balsa?

 

[David Schwantz]

Thanks Woody, if you look at the pics, the 2nd one is of the MMT. It is rear eject. MMT will come down on a streamer

 

[David Schwantz]

They were on Thingiverse. I just blew them up. Pun intended

I bought one about 6 months ago. Waiting to fly it. Hopefully in the next few weeks!

What size is the LOC tube? I'm assuming it took a few times to scale it right?

Hi PS. I am scratching my head on how to make sure the main comes out. Can you describe what you did? Or post a pic or 2? Thanks, Dave.

 

[PSLimo]

Hi Dave,

I'm not the best at describing but I'll give it a shot with pic's. This is what it looks like on the way up and down:

The insides on your 5.5 tube build would require a 5.5" coupler tube the length of the longest motor you're planning on using for rear ejection. I mounted the timer on the motor mount tube inside of the coupler tube. Then you need a piece of coupler tube stop so the motor doesn't crush everything on the way up. You can see it inside the main tube here:

Here's how the chute is packed. It looks different stretched out but the chute's actually very close to the motor ejected pod with lots of Kevlar behind it so it has to come out:

The chute protector isn't in the pic. Very simple and fool proof rear ejection for a bomb. I hope this helps your build.
