Benjamin Kerman's Welding Supply Co. in cooperation with Instell Incorporated proudly presents: Instell Incorporated Experimental Technologies Continued Note: Not all values listed in screenshots are correct DOWNLOAD REMOVED DUE TO NEW EULA Original Thread We at Instell Incorporated pride ourselves in customer satisfaction. We wish to give our customers only the greatest and most fashionable ways to ride their reusable ICBMs. Our engineers are ready and eager to work on any project that can get them close to the liquid oxygen again. Here at Instell we have only the best of experimental technologies, because finished products are just too mainstream. Why spend precious funds on testing when the customer can do it for you? At Instell we believe in shooting for the moon, and even if we miss, our craft melted on the way up. SCRAMJET ENGINES! New from Instell, the Semi Combustible Ramjet. Have you ever thought that stuffing air and fuel into a tube until it exploded was a bad idea? We did, but we kept trying anyway until we figured out that shoving more air in makes it explode out the back of the tube! [WARNING - Sharp edges, high temperatures, and ludicrous G forces may cause death, dismemberment, and or hallucination] We at instell incorporated are proud to offer a selection of two wonderful scramjets: XE-101 and the XE-202. Both are scramjets and are built to propel your spaceplane to hypersonic speeds. They become more powerful and efficient the higher they are and the faster they go. Advantages of scramjets: Very efficient at high speeds/altitudes Very light Can function at very high altutudes Is the physical representation of acceleration Does not require intake hogging However it poses a couple of challenges: Must be going past mach 3 to function Engines have a tendency to cause other parts to overheat due to atmospheric heating. Engines are more efficient in the upper atmosphere ELECTRIC ENGINES! Introducing the XE-303/E electronic turbofan engine! This engine is considerably more simple to use than our Scramjets. This engine is excellent for subsonic crafts, especially those on other planets. Since it doesn't rely on combustion to power its turbine, it will run in any atmosphere. It's perfect for aircraft transports on other planets! Advantages: Can run in any atmosphere Small onboard battery supply Cheaper than a traditional basic jet Very quiet Makes for a great air conditioner in a pinch Disadvantages: Cannot go above Mach 1 Can only be radially attached A bit bulky PULSE DETONATION ENGINES! Introducing Instell's latest work of mad science: The XE-404 Pulse Detonation Engine! This engine is the perfect companion to the XE-101 and 202. It has a maximum speed of mach 6 and sounds like a very, very loud and explosive jackhammer. Despite using the most advanced coolant systems that Jeb could find in his junkyard, this engine still has a tendency to overheat, so watch out! Advantages: Can easily take a SCRAMjet up to the required speed. Has a speed ceiling of mach 6. Operates well in the same flight conditions as a TurboRamJet. Can cook a burger in 6 seconds flat. Disadvantages: LOUD!! Cannot reach as high of an altitude as the XE-101 and 202 Can overheat easily Changelog *** v.2.1 *** * Added the "M.O.I.S.T." oxidizer radiator * Tweaked some values *** v.2.0 *** * Updated for 1.3 * Changed some strange values * Tweaked scale of hyperintake and inline SCRAMjet * Fixed things up

First off, what is a scramjet? This: http://m.imgur.com/u6w1LhQ It functions as a low-efficiency jet engine at sea level, and, when travelling at speed, provides an extra, sudden kick within its velocity range. Too fast or too slow and it will be inefficient. This would be good forpayloads with a variable fuel usage, but for SSTOs with strict fuel restrictions, not so well. We have jet engines and this closely resembles a Rapier engine, but a Scramjet is something we do not yet have. Oh, and they produce a LOT of heat. what are your thoughts?

Ramjets and scramjets; and special material layers. Today I have several suggestions to improve several parts of game related with flight in atmosphere. These suggestions are derived for several problems that I saw. 1. Ramjet intakes (ram air intake and structural intake) are relatively unrealistic (taking in count that all the parts of game has a moderate realism). 2. Is very difficult obtain high hypersonic and ultrasonic* aircrafts, due that air intakes of any type and the most part of winglets and wings are destroyed over speeds of 1300 m/s. To these problems I suggest several new parts and fixes: 1. Make ramjet intakes a little more realistic, this mean make these to only work at supersonic speeds, speeds over 340 or 400 m/s. 2. Add scramjet intakes, special new intakes able to support very big quantities of intake air. Also, these intakes only would work at high supesonic speeds, over 500-600 m/s. 3. Add the possibility of add special material layers to all the vehicle, like a extra option or a thing like "undefined size part". These layers would have a variable price based in the size of surrounded vehicle or specific part. For now I suggest these possibilities: - Titanium (Laythanium in ksp?): it would make to the vehicle more resistant to pressure and pressure changes, and a little more to heat; with big heat mounts can not protect to the vehicle or part to pressure and overheat. - Ceramics: it would make to the vehicle more resistant to heat and friction (except to engine parts), this mean the possibility of obtain durable and manageable hypersonic aircrafts, but this type of layer is weak to big pressure changes and impact, and can be removed by these conditions. Thanks for read. _______________________ * Ultrasonic speeds are the same than atmospheric reentry speed, so a ultrasonic aircraft is a very advanced aircraft capable to fly at these extreme speeds.

To be more specific, I'd like to see two things: A liquid-fueled scramjet (Supersonic-Combustion Ramjet) engine that can propel a craft from about 900 meters per second at roughly 10-12 km altitude above Kerbin up to 2-2.3 kilometers per second to push apoapsis between 120 and 160 kilometers with periapsis either above sea-level or to a depth below sea-level of less than 100 km A Solid Fueled Integrated Rocket Ramjet (basically a solid-fueled ramjet that initially operates as a solid-fueled rocket-booster, and once the rocket-portion has burned out, it's built up enough airspeed for the booster's casing to act as the duct of a now-air-breathing solid-fueled ramjet engine that can accelerate the vehicle the rest of the way up to the speed and altitude at which the above-mentioned liquid-fueled scramjet can take over the task of accelerating the payload to orbit.
