Can somene enlighten me on the history of EnerJet?
Was Enerjet a separate company purchased by Centuri or just a separate division?
I know Centuri was purchased by Estes/Damon but what happened to EnerJet?

The first composite "Enerjets" were developed by Irv Wait at RDC (rocket development corp).
I do not know if they were then called "Enerjet" or not.
Centuri then bought/absorbed this company.
From that point on, those composite motors were definitely called "Enerjets"
The consumer offerings included the original Enerjet-8, The 29mm Enerjet E24, F52, and F67.
There was supposed to be a 18mm D21 released around 1971-72, but it never made production.....very similar to the situation we now have with the composite Quest D that has been coming "soon" for the last two plus YEARS !
Supposedly they made larger "commercial/professional" motors above the "F" class.

The Enerjet line of rocket kits, (Athena, Aero-Dart, EggCrate, Nike Smoke, Nike Ram, and Pterodactyl), were strictly Centuri items.

Centuri then used the "enerjet" name on all of their regular black powder motors in the late 1970's.

No, my fault. I confused this with another thread over at TRF, and after I looked at it, realized it was about Enertek...that's what I get for postiing too quickly after 4 hr of sleep...as Gilda (SNL) used to say "Never mind..."

Irv offered for sale and called his Enerjets, Enerjets before he sold his company to Centuri.

See the 1968 RDC catalog at Ninfingers website


RDC did indeed offer for sale much larger composite rocket motors to other commercial markets. I have pictures around here somewhere of them.

Irv patented the Centuri "Sure-Shot" igniter; which in RDC catalogs were known as Igniterite.

Enerjet is / was also the name of a coffee-flavored caffeine-loaded hard candy.

I should have bought a case of those when I had the chance...

Here's some more "Eye" candy..

Notice the 4 port composite motor and for the Enerjet notice how the composite propellant burned to the top and lit a fuse that was wrapped around the outer smaller tube, and then threaded back into the ejection charge.

enjoy

and even more EYE Candy. By the way, thats IrV Wait holding the motors himself a few years back. Notice the Irv Wait built RDC models in his basement workshop.

Thanks for the info guys.

The Enerjet line of rocket kits, (Athena, Aero-Dart, EggCrate, Nike Smoke, Nike Ram, and Pterodactyl), were strictly Centuri items.

Was that the entire line or just a sample?

Those kits listed were the entire "consumer" line of Enerjet rockets.

The "commercial/professional/sounding" Enerjet kits included the 1350, 2250, and 2650.

The 1350-small payload version is very similar to the Nike Ram except it had a Plastic fin-can that was shared with the Centuri Phoenix Bird, and Estes Challenger 2.

The 2250 and 2650 were 3x29mm cluster engine rockets and were the forerunners to modern High-power rocketry we have today. The main difference between the two was the 2250 had a 2.25" diameter payload section and the 2650 had a 2.65" I.D. Payload Section.

I have cloned all of the consumer Enerjet Line, and have an original Enerjet Nike Smoke kit in my collection....the main difference between the Centuri and Enerjet Nike Smoke kits is that the Enerjet version has a "real" smoker payload in the nose cone and uses E & F motors....the Centuri kit did not smoke and used 18mm A-C engines. The physical dimensions of the two are exactly the same. It is actually quite easy to convert a Centuri Nike Smoke into an Enerjet one with some additional ST5 tubing, an ST5 cone, and a 29mm Engine Mount.

Yes, but we usually refer to the character. You know, like "Homer Simpson said..." or "Borat said...."

Irv definitely made motors larger than F's as the attached photo shows. He also had a reloadable motor in the early 70's. LAUNCH Magazine ran a nice article on Irv and his rocketry activities in an earlier issue.

The Enerjet 8 composite motor had a fuse delay element. The fuse was ignited by the motor's exhaust, burned up the side of the motor, and then around the ejection charge tube with the number of wraps determining the delay.
See the photo in the 1968 RDC catalog on www.ninfinger.org in the model rocket section.
