LAKE HAVASU CITY, Arizona USA — Trojan Rocket Motors, in cooperation with Contrail Rockets is pleased to announce that as of January 22, 2008, the first 15 Trojan hybrid rocket motors were submitted to the Tripoli Motor Testing Committee (TMT) for product certification.

Tripoli Motor Testing is now back testing motors according to Paul Holmes, TMT Chairman.  Paul Holmes has stated that TMT will look to test the motors which have been submitted the third weekend of February (15-17th), 2008. 

Trojan Rocket Motors, along with Contrail Rockets, has patiently awaited this notice from TMT that they will begin testing hybrids again at their location.  Along with the Trojan Rocket Motors which were submitted earlier this week, TMT has been holding five other Contrail Motors, which are to be certified for the current Contrail 54mm hardware line. 

Trojan Rocket Motors has been anxiously awaiting this announcement so that we can also announce the first Trojan Rocket Motors promotion.  The promotion, which is to begin on January 28, 2008 will allow for customers who have been anxiously awaiting the release of these Trojan hybrid motors to get an amazing deal on the hardware and reloads.

Bad business plan. Those use standard tanks and thus are more "commodity driven". They retain all the on-field labor intensive aspects of all hybrids including Trojan, Contrail, Hypertek, West Coast, RATT rocks, and even the refused U.S. Rockets hybrids, the first hybrids tendered to TRA TMT ever.

Some range of impulse and average thrust would be nice. I understand if they are waiting for the TMT results to actually choose a designation for each motor, but they MUST have some kind of idea how they will test out.

contrailrockets Certified Level Two   Joined: Oct 2007 Posts: 42	Re: Trojan Rocket Motors offers new motor promotion A number of questions have arose here on some of the forums, as well as in private phone and e-mail conversations about the Trojan Motor Hardware and Reloads. I will cover some of the questions in this post… Question 1: “Will I be able to purchase Hypertek style tanks, for Trojan motors through Contrail or Trojan Motors?” Answer: No, there are no plans now or in the future for Contrail or Trojan to offer the reduced diameter Hypertek tanks. The Systems are designed to use the tanks which are already in the field being used, or going unused. Customers who are new to Hybrids would be better suited purchasing a Contrail style motor rather than the Trojan Motor and HT Tank Separately. Question 2: “What performance can be expected from the Trojan Line of Motors?” Answer: The Trojan Line of motors will have performance as follows. 54mm 300cc, 440cc and 825cc Motors will have Average Impulse numbers as follows: Slow (3/16 Injector) 175 N-250 N Average Impulse Medium (1/4 Injector) 275 N-350N Average Impulse Fast (5/16 Injector) 500-600 N Average Impulse X-Fast (3/8 Injector  Not Yet Submitted to TMT) 700-800 N Average Impulse 75mm 1685 and 2800cc Motors will have average impulse numbers as follows: Slow (1/4 Injector) 300-375 N Average Impulse Medium (5/16 Injector) 550-675 N Average Impulse Fast (3/8 Injector) 725-850 N Average Impulse X-Fast (S Injector  Not Yet Submitted to TMT) 900-1100 N Average Impulse Total Impulse Number of the 54mm Hardware will vary based on tank size, fuel type, injector used, and temperature. The Trojan Motors were designed to be competitive with the Hypertek line of motors. Customers will find that the lower average impulse motors will give higher total impulse numbers. The 54mm Line of motors using the Black Smoke Fuel (submitted to TMT) at 70* F will achieve a total impulse of I-K Motors (Similar to HT Motors). Similar Information can be expected for the 75mm line of motors. 75mm Motors will fall in the L Impulse range. Customers looking for a high total impulse grain configuration will be happy to learn that the Platinum Performance Fuel will be submitted in the Trojan Line of Motors shortly. Question 3: Motor Designations are not yet available, when can we expect them? Answer: TMT will post certification information once they have certified the hardware and reloads. TMT bases motor certifications on 3 fires of each motor designation. Trojan Rockets will post all information to the Trojan Hybrids website as soon as it is received from TMT. Question 4: The Trojan Website looks empty, when can we expect updates? Answer: Expect some updates In the coming week, with detailed photo’s, instruction manuals, videos etc. By the time of motor certification the website will be a fully functioning site. Question 5: Can I order individual hardware at this time without the promotion? Answer: No. At this time the only available items are in the promotion.

Steve_Shannon When in doubt, ask Keenan   Joined: Aug 2006 Posts: 1978	Re: Trojan Rocket Motors offers new motor promotion I'm afraid that adds confusion. You seem to be using the term average impulse when you really mean average thrust. Also, as I'm sure you understand better than me, the units for average thrust are N (not Ns, which stands for Newton second, which truly is the unit for impulse) So, for instance, in the line "Slow (3/16 Injector) 175 Ns-250 Ns Average" do you really mean to say 175 N - 250 N average thrust or are you saying that the range of impulses for motors assembled with that size injector will be from 175 Ns to 250 Ns, depending on tank size. I cannot believe the latter as that would put it into an H range. p.s. I still grin at the memory of your Contrails M in my rocket in Canada a few years ago!

"How to become a dealer" Answer: "Anyone looking to become a dealer of the Trojan Line please contact This email address is being protected from spam bots, you need Javascript enabled to view it for more information" Dealer Information will be gone over at that time offline. Question 2: "Are Sparky reloads coming out for the Trojan line?" Answer: "If there is enough interist and customers don't mind a lower total impulse motor it is possible. They may be geared more to the larger motors as well..."

Secondly with what avionics have they been tested. While I appreciate the unending back and forth search for equilibrium inherent to an external passive oxidizer feed, seems some of the hybrids are worse in this respect than others. How fare yours?

I can't speak for the Trojans (or for Tom and Tom) but I can tell you this. I did my L3 in 2005 on a Contrails motor and I could not detect any of the thrust surging that is so detectable in some motors. The motor sounded like a solid motor with a bit of a whistle to boot. It was great! I would hope that the Trojans exhibit a similar characteristic. I used a G-Wiz MC and Missile Works RRC2 for my electronics and both functioned perfectly.

edwardw Certified Level Two   Joined: Aug 2006 Posts: 53	Re: Trojan Rocket Motors offers new motor promotion Between going back to school and running another business I'm hoping to have them ready for MHM. Right now they are 95% complete. I just want to get everything certified at one time instead of multiple certification sessions. It is very hard choosing what fuel combos to certify and what ones not to certify. Right now I'm looking at 3 different ones. Edward

From the Alpha Hybrids blog, I found this statement: "If one wishes to purchase another 440cc flight tank and injector so that multiple flights can be done in a day without having to bring a bigger supply tank they will be $50 for the set." So they must have a way to contain the nitrous in the tank/injector until ignition. Personally, I would like to see this type of hybrid on the market as it opens up the world of staging to self-contained hybrids, like the old AeroTech units did. I would also like to see AeroTech bring their hybrids back to market. http://alphahybrids.blogspot.com/

edwardw Certified Level Two   Joined: Aug 2006 Posts: 53	Re: Trojan Rocket Motors offers new motor promotion Thanks John for pointing me here. The hybrids are similar to the old Aerotech hybrids. You fill a tank with a specified mass of nitrous oxide and then you mate that to the case immediately before flight. The one great thing is that you can have a few prefilled cylinders ready so you can fly w/o having to fill in the field. I prefer to fill at home because it is much more controlled environment. The injectors come with the tank so that you don't have to rebuild them - you can put a new one in and fly. If anyone has any questions feel free to ask. Edward

ddmobley Administrator   Joined: Jul 2006 Posts: 3189	Re: Trojan Rocket Motors offers new motor promotion Edward, how does you nitrous release work? The old AeroTech hybrids used a black powder pyrovalve. Are you using something similar, or a burst-disk?

02-06-2008 06:50 PM  #26
edwardw Certified Level Two   Joined: Aug 2006 Posts: 53	Re: Trojan Rocket Motors offers new motor promotion I use a injector I developed that works very fast and doesn't require a special BP pellet like the Aerotech ones did. It also atomizes the nitrous very nicely so that it is a smoother burn. Edward

ddmobley Administrator   Joined: Jul 2006 Posts: 3189	Re: Trojan Rocket Motors offers new motor promotion What triggers the flow of nitrous?

02-06-2008 07:25 PM  #28
edwardw Certified Level Two   Joined: Aug 2006 Posts: 53	Re: Trojan Rocket Motors offers new motor promotion Basically it is a piston driven system. It is hard to explain here - and I really don't want to publish it either before the motors are out. There is a piston and when you light the preheater which is 3 pyrodex pellets the piston opens and injects into the motor. It is a part that is re-usable. Edward

edwardw Certified Level Two   Joined: Aug 2006 Posts: 53	Re: Trojan Rocket Motors offers new motor promotion I've often thought of publishing how the injector works as open source, and I likely will after I cert them. Though the only manufacturer that I would be concerned about blatantly copying the design said they won't do prefills, so I guess I wouldn't have that issue. And yes, the injector is way below 62.5 grams, and the user supplies the needed parts. Edward
