Gotta be @Daddyisabar's Grandpa...

From this model, Maurice Poirier explains to Earl R. Kingston, how he is building a 12 foot long gas rocket with which he expects obtain new information about the stratosphere in Arcadia, California, June 19, 1936. The rocket will carry instruments in its nose for measuring cosmic radiation, temperature and general atmospheric conditions. The nose cone will fall back to Earth by parachute when the maximum height is reached, but the body of the rocket will explode and be torn bits, eliminating danger to persons below. it will weigh 175 pounds.

From the thread title, I was expecting a 6 inch upscale Big Daddy.

That happened well prior to WW2. Nobody had heard of Werner Von Braun, or the V2. I'm pretty surprised that anyone was experimenting with rocketry that seriously at that time, at least on their own finances. Thanks for posting, Lakeroadster, absolutely intriguing.

Actually, in 1936, Werner Von Braun was probably known at least in German rocketry circles, as he was mentored by Hermann Oberth, author of important rocketry books at the time.

"In the autumn of 1929, Oberth conducted a static firing of his first liquid-fueled rocket motor, which he named the Kegeldüse. The engine was built by Klaus Riedel in a workshop space provided by the Reich Institution of Chemical Technology, and although it lacked a cooling system, it did run briefly. He was helped in this experiment by an 18-year-old student Wernher von Braun ..."

Don't mind me. Just practicing geekery with stuff I learned about 2 weeks ago.

FYI. Sharknader will be flying again this weekend at Hartsel- Tripoli Colorado.

Sharknader getting ready for second launch. Gonna fly it again!Cluster of (3xA10)4=12 motor cluster. That math is purdy hard and takes a fair amount of book learning. Hopefully being named after such a highly intellectual movie the RSO will be impressed by my high level of competence. Last time one of the booster motors CATOED on the first stage. Still flew ok, one stack was a bit out of sequence. Enough thrust to overcome any sin. Put a coat of CA on the toasted bits, now stronger than before! Love me some tractors 🚜!

Goofed around a bit in Open Rocket. Neat bird.

Ralph said "Unsafe at any speed"... I don't believe him, never did.

Really Mr. RSO, it is the most stable rocket at the launch today! The fins are used just to make it not look so funny! Independently stacked tractors don't have the problems of clustered, staged rockets with motors in fin cans on the backside of the rocket, where here they should NOT be.

Still not good enough as one RSO on Facebook would not let it fly. Clustered staged rockets are still too scary and have a bad reputation!

That CP is way too low. Needs to be brought up by something stupid like a plastic Wile e Coyote!

They fire banned the Tripoli launch so maybe next weekend at SCORE. Some purple lable A10s would be better for the upper stack but it is just nose blow recovery.

Print out the above graph and explain to the RSO that the design has been "exhaustively analyzed" (those guys like paper) :barf:

Fortunately I have enough street cred with the top men to fly my creations, no matter how abominable. On the away pad with a fire crew they can safely see an awesome flight or a good crash. Either way, very entertaining!

The geographic center of Colorado! Do you guys get much extra altitude in that thin air?
Yes! For some reason the rockets fly higher and come down a whole lot faster. Everyone upsizing chutes. Recovery walks are, for some reason, uphill both ways, especially coming back. Almost impossible to burn but, for some reason, still applicable to burn bans. No equipment on site to remove rockets from rocket eating trees. The Bison only like motors N and above. Can get cold in the morning but, for some reason, you can't wear an orange down filled jacket with the hood on tight.
