1 2000 Edition HIGH-POWER Reloadable Motor System Products * Combustion Chamber Reload Kit Bottle Adapter Electronic Balance & Calibration Weight Pyrovalve Tools Fill Hose & Cylinder Adapter Krytox Grease Nitrous Oxide Flight Cylinder *Patented and Patent Pending Welcome to the future! The AeroTech RMS/Hybrid Reloadable Motor System is the world's first commercially available reloadable hybrid propellant rocket motor and has successfully completed the Tripoli Rocketry Association's beta-testing and motor certification programs. The RMS/Hybrid is a reliable, versatile and cost-effective means of powering your high-power rocket vehicles that will grow with you as you expand your rocketry horizons. Each RMS/Hybrid motor is capable of delivering a wide range of programmable time-thrust profiles, and is easily converted to conventional solid propellant operation with AeroTech's standard RMS High Power reload kits! A hybrid propellant rocket motor employs separated propellant ingredients in two different physical states (generally the fuel is a solid while the oxidizer is a liquid). In AeroTech's RMS/Hybrid motor design, pressurized liquefied nitrous oxide (N 2 O) is employed as the oxidizer while cellulose ((C 6 H 10 O 5 )n) is utilized as the solid fuel (patent pending). Advantages of hybrid propellant technology for the high-power rocket enthusiast include markedly lower cost per flight than solid propellants, less restrictive shipping regulations and elimination of the need to comply with various aspects of the federal explosive laws that currenly plague the purchasing and storage of large solid propellant rocket motors. Motor Diameter in Millimeters Maximum Total Impulse in The RMS/Hybrid motors use a high pressure aluminum alloy cylinder to store the liquefied nitrous oxide oxidizer prior to flight. The cylinder/ valve assembly is mated to a standard RMS 54mm motor casing and aft closure via a specially designed forward closure/n 2 O injector plate assembly. The forward closure design includes a provision for a combustible Pyrovalve (patented) which restrains the flow of N 2 O until the moment of ignition. Like the original solid propellant RMS, each RMS/Hybrid precision machined anodized aluminum rocket motor can be flown again and again with easy to use RMS/Hybrid reload kits. After purchasing one RMS/Hybrid motor, the owner can choose from a variety of thrust levels produced simply by configuring the forward closure injector plate with either 2, 3 or 4 injection ports or "jets". Owners will also find the reload kits inexpensive and easily installed in a few minutes. The nitrous oxide required for use in the RMS/Hybrid is widely available at auto performance shops at low cost. And the flight cylinders used for storage of N 2 O are easily refilled by the user or an RMS/Hybrid dealer prior to flight. Best of all, no special ground support equipment is required to launch rockets powered by RMS/ Hybrid motors! RMS/Hybrid motors reflect the same reliability, quality and professional design that have become the trademark of AeroTech's solid propellant RMS products. By making most of the expensive parts of the motor reuseable, the cost per flight is greatly reduced. In addition, RMS motors produce far less non-biodegradable waste than singleuse motors. The basic design of the RMS motors also permits performance characteristics simply not feasible with single-use motors. Because RMS/Hybrid motors are of modular design, each reliable and durable motor can use a several combinations of forward closure injector plate configurations and RMS/Hybrid reload kits, including the spectacular EFX and Turbo reloads! RMS/Hybrid means unprecedented versatility, user interaction, savings and enjoyment! When you add it all together, the RMS/Hybrid is an unbeatable value combining price, quality, innovation, interaction, performance and support.

6 Hints and Tips for Using AeroTech RMS/Hybrid Products 1. Electric matches are not continuity safe will all firing systems! Use low current (Less than 30 milliamp) continuity circuits only! 2. Always use grease sparingly. O-rings are sufficiently greased when they exhibit a uniform "shine". When preparing hardware for use, lightly apply a bead of grease around the outer edge of the threads at each end of a case. Then screw both closures on and off their respective ends of the case in order to thoroughly distribute the grease amongst the case and closure threads. 3. Remember to use only Krytox grease on the forward closure's internal sealing areas (specifically the Pyrovalve o-ring and flight cylinder/forward closure threads). Ordinary greases are susceptible to spontaneous ignition or explosion when exposed to pressurized nitrous oxide. If you don't have Krytox, don't use any grease! 4. When assembling a Pyrovalve element into a forward closure, avoid getting any grease on its exposed surfaces. Contamination of a Pyrovalve's surfaces with grease may result in less reliable ignition. 5. Always check a reload kit's contents against its parts list. Never use a reload kit that is missing or contains questionable parts. Always inspect reload kit o- rings for nicks, cuts, thin sections or other defects (defective o-rings may cause motor failure). Don't use any Pyrovalve element that has been dropped, is visibly cracked, or has any other obvious defect. At its discretion, AeroTech will replace any reload kit that is missing or contains defective parts. 6. When assembling an RMS/Hybrid motor, be sure to read and follow the instructions! All parts must be assembled in the correct order and installed in the proper location (we've seen o-rings stretched around end closure threads, for example). A real indication of trouble is if you have reload kit parts left over. Check your assembly again, or call AeroTech. 7. After threading the forward and aft closures into a motor casing, be sure to lightly seat each closure against the case to help insure that combustion gas leakage does not occur during motor operation. 8. Flight cylinders may leak slightly after filling for the first time. However, after a few hours under pressure the pin valve sealing washer normally conforms to the inside of the pin valve and effects a tight seal. Cylinders should be capable of holding a full charge of nitrous oxide for several weeks after this "break-in" period (AeroTech requests the return of any cylinder which fails to seal positively after several attempts are made to fill it). 9. AeroTech strongly recommends that flight nitrous oxide cylinders always be weighed just prior to flight to verify the net weight of nitrous oxide contained in the cylinder. It is important that the cylinders be filled to within 5% of AeroTech's recommended capacity for best system performance. 10. Igniters should be installed so that they directly contact the Pyrovalve element. Chances of a misfire increase if the igniter does not make positive contact with the Pyrovalve element. 11. Thoroughly clean a motor after each use. Residues can prevent proper sealing and result in hot gas leakage and subsequent motor failure. 12. When preparing your igniters it is important that the top of the masking tape "tube" be simply pinched together, not covered with another layer of tape. It is also necessary that the opposite end of the tape be securely attached to the electric match leads. Otherwise, the pressure generated by the burning black powder can eject the electric match rearward from the tape tube without igniting the Pyrovalve, causing a misfire. 13. Black powder was selected for ignition enhancement because it is widely available and does not require BATF permits for purchase, storage or use. For those of you who have access to thermalite igniter cord, it can also be used with equal success. A 3" piece, folded to a 1" length and taped to the end of the electric match, will produce good results. 14. A relatively low-strength thread locking compound is used to secure the pin valve body to the flight cylinder neck, in case it ever becomes necessary for us to disassemble them to inspect the valve components or for repairs. We have discovered in a few instances that the pin valve may still be prone to loosening from the cylinder under certain conditions, such as when unscrewing the flight cylinder from the forward closure after performing the Pyrovalve leak check. A drop of cyanoacrylate (CA) glue on the mating surfaces of the valve and cylinder can be used to prevent the valve from loosening again. NOTE: Do not get any CA on the threads of either the valve body or the cylinder neck. Apply to the flat surfaces only. 15. We want to emphasize that a light coat of petroleum-based grease applied to the outside forward (bulkhead) end of the liner greatly improves the ease of liner removal after a flight. Apply the grease on the forward 3-4" of the exterior liner surface prior to loading the liner assembly into the motor case. The forward ends of ungreased liners may have a tendency to stick to the casing in isolated spots. 16. We have discovered that if a RMS/Hybrid -powered rocket is involved in a crash due to failure of the rocket's parachute deployment system to function properly or other reason, the extreme deceleration caused by impact can result in a small quantity of char (carbon) deposit from the interior of the motor combustion chamber to be forced through the injector plate orifices, through the cylinder pin valve opening and into the flight cylinder. This char deposit can result in the inability of the flight cylinder pin valve to effect a tight seal during a subsequent filling. In the event that this happens to you during a flight attempt, we recommend that you load the flight cylinder with a small amount ( grams) of nitrous oxide according to the procedure specified in Chapter 1 of your owner s manual, then rapidly discharge the N 2 O through the cylinder filling adapter assembly. Hold the flight cylinder with the pin valve pointing down during this operation. This orientation will discharge liquid nitrous through the pin valve and will help to dislodge the deposits from the cylinder and valve components. Repeat this process if necessary to purge all char deposits from the cylinder and valve. The pin valve should seal normally after being cleaned in this manner. 17. AeroTech recommends that minimum diameter rockets be designed to separate just above the flight cylinder/motor mount tube interface to prevent tube damage upon landing. 18. Motor mounts should be sealed off from ejection charge pressurization to minimize the possibility of motor ejection. 19. Unnecessary use of Krytox grease on the inside of the casing and other areas causes "bleaching" of the anodization dye. 20. Fuel liners occasionally appear to "burn through" in isolated spots. A small carbon deposit on the inside of the motor case may result. This does not affect proper motor operation and can be easily removed during motor clean up. AeroTech, Inc S.
