X49 'ELECTRA' SCRAMJET Specifications

21 March 2003 Draft, Millennium Twain
(typos? -- please send us your corrections!)

Whoa! We finally have the very first draft (and, again, very) preliminary ElectroAerodynamic design specifications of the X49 ScramJet StratoLiner -- henceforward named the X49 Electra? X49 Exxelerator? ElectroSlider? ElectroJet? [Send us your name ideas!!]

And ditto, regarding the Earth's 1st 'Electroshell', 'Ionoshell' -- Electrogravitic Aeroshell design, name and illustrations!

For the X49 'mass-fraction' specs -- vehicle, fuel, passenger, mass/volume/velocity numbers -- click on the ElectroShock graphic below, third image on this page, or journey boldly to unamity.com/specs ...

. . . world's first public publication of an airbreathing 'ScramJet' (HyperJet, SpaceJet, PlasmaJet) SpaceLiner design!!

The above sketch, X49 'ElectraScram' Vortex Engine Topology, shows one of the two Rammed-Air inlets -- 'nostrils' -- on the nose of the X49 FireShip. The rammed-air flows in a spiral (helicoid) down the nozzle, which will shrink to pressurize the air for injection into the combustion chamber. In addition to compressing the atmosphere, the RamScoop funnel will electrically condition, or charge the air. It will place a highly negative electrostatic charge on the air -- in this 1st preliminary design -- by having a high negative voltage on the helicoidal vortex chamber walls.



The combustion chamber helicoid, which follows AFTER the compression chamber helicoid, is intended to act as a 'valveless pulsejet'. A vortex diode. That is, it will receive the injected compressed charged rammed air at a node in the helicoid wavelength. The node and injected compressed air, and side-injected hydrogen fuel, will act as a virtual (or plasma) wall or valve -- blocking the return flow of plasma after ignition of the oxygen (from the air) and hydrogen!

The ejected exhaust, high velocity reaction mass, is pure (hot, electrified?) steam!

Further -- to complete the 'circuit -- the injected hydrogen will ALSO be pre-charged. Charged with a high positive voltage! In this way, the plasmajet or electrojet rocket engine is not only valveless -- it is electrodeless. [You can search for other discussions of the plasmajet concept using the keywords pulsed plasma detonation wave engine, pdwe, and similar ...]

The Ignition/Combustion Vortex Chamber is also illustrated below, in simplified form, along with the Atmosphere Pre-Charging and Compression (Scram/Hyper-jet inlet) -- in one long multi-wavelength helicoidal tube which is the whole of the Hyper/Plasma propulsion assembly. In order to illustrate the concept of the amplitude nodes and anti-nodes, and the Injected Air Compression, and the Vortex Diode (Valveless Flow Direction Control) -- in order to show all of that simply, I have illustrated the multi-wavelength helicoid as a series of cones! Two cones represent one-half wavelength of the helicoid, i.e., a combustion chamber. One cone, large opening towards the trailing edge of the stratoliner, represents the thrust nozzle. One to three, or more, cones could represent the atmospheric air inlet, compressor, and pre-charger.

This illustrates, clearly, the next design aspects we have to tackle. How much reduction in helicoid amplitude -- in the compressor/pre-charger -- do we require in order to condense the air sufficiently for combustion in the burner/rocket chamber? How much reduction in amplitude in order to achieve the Vortex Diode valve action? Will we require the ability to vary the size of the air inlet, the mouth, in order to increase atmospheric consumption at high altitudes, or reduce it for high Mach numbers? To vary it with pressure and velocity.

Can we just 'build-in' to the aeroshell the largest mouth/nostril openings required, and then shunt off extra flow under the belly of the Fireship, in order to minimize L/D loss?



So; the broad questions we have for our colleagues and collaborators now are: 1) Where should we be going -- in scramjet engine topology, injection, charging, pulsing or continuous thrust -- in order to achieve a long life-time vortex diode (valveless) engine system? 2) In order to make the simplest, most reliable, and throttleable ignition system -- long lifetime or low replacement costs, with unlimited engine on/off capability -- how can we make the best use of our knowledge of common-sense plasma physics and vortex dynamics? Your suggestions are now being heard, shared, and incorporated in this X49 'ElectroScram' design!

And, in addition to contributions on the X49 FireShip naming, we are looking for collaborators to share their design graphics, for posting at FireShips and Unamity. ElectroGravitic, AntiGravitic, or ElectroAerodynamic design considerations for the X49 and similar spaceplane concepts. That is, whatever the 'buzz'-phrase you use -- we are looking for artworks that illustrate the magnetic, electric, electromagnetic, and electrodynamic concepts and systems that either negate vehicle drag (friction), or provide propulsion, or both.





We are talking to Electric Spacecraft Journal, JLN Arda Labs, American AntiGravity, and many others about tracking down and posting the many ideas of electroaerodynamic flight systems illustrated or conceptualized over the last few decades. For the most advanced, and applicable to the X49 Spaceliner design, we will create dedicated webpages for illustrating and explaining the concepts in detail. And we will launch, immediately, a links page for our collaborators and other websites related to ElectroAerodyamics.

The above graphic, ElectroDynamic X49 Aeroshell Drag Negation, illustrates our first proposed system for achieving low or null drag. Low or zero friction in the atmosphere. By electromagnetically 'fluxxing' the hull/body of the X49 FireShip -- we hope to 'push away' the supersonic atmosphere envelope around the vehicle. That is, 'grease' the FireShip's aeroshell with a rapidly (high frequency) oscillating electric field. [Imagine a RAPIDLY vibrating knife-blade cutting through the atmosphere ...]

Again, we are looking for designers worldwide who want to comment and critique this drag negation system. And help us in refining and testing it. In chronicling and developing a variety of drag reducction concepts, for publication. Systems that mulitiply the vehicle L/D, lift-to-drag, from twenty or thirty, to perhaps 50 or 100 or 200! ElectroAerodynamic designs that demonstrate the concept of null or zero drag! 'Superconductivity' as applied to aircraft aerodynamic drag!!





And, we're not finished yet! A vortex, and a FireShip, are 'living' systems that only function in HARMONY with nature. All the design details have to fit, or none of them do!

This illustration of the 'perfect' matching of engine and aeroshell vortices makes the point. And further illustrations, to come, will refine it.

This view is of the nose of the X49 Electra ScramJet. She is coming right at you! On the Starboard side, BOTH the ramjet injector AND the vehicle aeroshell have to generate a CCW (counter clockwise) vortex. These vortices grow together as the air approaches the aeroshell -- reach a maximum inside the ramjet tunnel and outside the X49 aeroshell -- and dwindle away together in the trajectory wake. Exactly co-propagating and co-aligned -- the Port side ramjet CW (clockwise) vortex AND aeroshell vortices must also act in unison. Not only with each other, but with the oppositely-swirling Starboard vortices which mirror them!

The wavelengths and phases of all these vortices have to match, in order to minimize the scramjet and aeroshell drag. Also, CCW starboard and CW Port aeroshell vortices produce a negative pressure on the top of the lifting body, and a positive pressure underneathe. Maximizing our lift, another way to increase Lift-to-Drag! [In addition to our electrodynamic systems for decreasing the drag!!]

And we KNOW there are GREAT vortex engineers in cyberland. Engineers who are already getting involved, in focusing our designs and expanding our team(s)!!!

Did we say we like art? !!!

We LOVE your creativity and connectivity. For the artists on our 'world team' -- please follow your inspiration. And send us your contributions of ink, colour, or composition. We will be posting and crediting and linking many 'electric' spaceplane, scramjet, and scram-dirigible designs in the months ahead. We want to include you in this revolution.

There is no better way to clarify, and motivate, and share, and 'fire' a world! Numbers, equations, and words are part of the puzzle -- yet the mind's eye, and the public eye -- play a thousand times greater role. Like the transistor amplifier in your radio or stereo.

Let the celebrations begin!
