Astroland Rocket





Several times per year, I along with my friends and family have visited Coney Island. To see the beach, have a dog, get pizza, take a walk, or do many other things (now one can see a Cyclones game also). For years, there was a rocket above the boardwalk. After starting in rocketry, I couldn't help but notice when certain objects might make nice rockets. Telephone poles, lamp posts, oil tanks, the empire state building, and yes also this rocket model at Coney Island. To add to it, there were a number of large circles at the base of the rocket. Each one invited a guess on what motor would fit the hole, and what kind of power it would take for this rocket to really fly. The large central hole would be perfect for an S motor with lots of flame and smoke, and the many holes around it would work with fast P or Q motors to give it enough thrust on takeoff. The mass distributtion would have to be shifted a great deal to make it stable, and perhaps it could never really be stable with such small fins. Also, the total weight would probably have to be reduced by half or so: The rocket is 71 feet long, and 14,000 pounds. This would be a record indeed for a "hobby" rocket (it actually would break the hobby level based on motor impulse and rocket materials) and would approximate what one needs in a V2 full scale model. (Well much longer, but about as heavy.)

That... would be epic.

The V2, according to Alway, had the equivalent of an X275000 with a 65-second burn time. A bit bigger than an S, but not that much.

X is actually a lot bigger than an S!

I think 32 times as big!

But remember the V2 engine carried the rocket to space, we just need a few thousand feet.
