Rocketry Planet

GORMLEY, Ontario CAN — The CAR Motor Certification Committee has tested and certified four new Pro98® reloads using our popular Vmax™ and Red Lightning™ propellant. With these new reloads we will have four different propellants available in our Pro98 line.

SLIDESHOW: Starting with CTI's new high expansion ratio 98-XL nozzle, destined for the M4770, followed by four graphs of the new motors.

The Vmax Pro98's are characterized by very high average thrust levels; perfect for a project that turned out a little too heavy or neck snapping launches on lightweight minimum diameter rockets. The K1620 reload uses CTI's new 1-Grain Pro98 casing while the M4770 reload makes use of CTI's new larger 98-XL nozzle that allows a higher expansion ratio. Currently only the Vmax 2-Grain L3150 is certified for use in AeroTech RMS™ hardware — the 1-G and 3-G Vmax motor types will be certified in the AeroTech RMS hardware shortly.

The new M1890-P Red Lightning reload creates a stunning red flame for more than 5 seconds and is certified for use in both CTI Pro98 and AeroTech RMS hardware.

The new motors:

Anthony, could we get a photo of the Red Lightning propellent? If not, I can wait until Roc Lake this weekend

You gotta love that nozzle and an L3000+, M5000+

Thats a lot of lifting power all by itsself, yesiree. 1/2 ton truck in 98mm package, whats there not to like?

1.5 sec M to a 12 sec M would be a nice 2 stage flight.

You know something I think you're absolutely right about that. You look at sounding rockets and as it just so happens the Nike-BB burns about 3/26.

One would think with a nozzle that stout and a motor with that short a burn, the nozzle would be reusable.

So, ~ 200mm motors then?

I wish. But we have plans for a 1/2 scale Nike/BB and a 1/2 scale burn would be just about the numbers R2K mentioned.

Add little thruster motors circumferentially (sensor and software initiated) to keep it flying straight(er).

BTW why do 1/2 scale when you can do 2x scale?

#9 Re: Cesaroni Technology announces four new Pro98 reloads

Why? There seems to be something distinctly unlucky about upscale and full scale scale-rockets!

Besides this is as much, maybe more, than I can chew at this point. But with a little help from my friends...who knows. Stay tuned.

I am still waiting for a full scale V2, Atlas, Redstone...

Would be great to see these kind of options in the O motors also.
