Hi. I am an aerospace engineer whose graduate and post-graduate research work was on pulsed detonation engines (PDE). My last engine (ground demonstrator) was designed to run on liquid kerosene and featured a single detonation chamber with dual rotary valve systems.

The picture bar on top shows a 4 in i.d. propane/air+oxygen powered PDE ground demonstrator. Here is a link to the video page of the Aerodynamics Research Center at UT Arlington where one can find video clips of some of the PDE work that my fellow PDE researchers and I were involved in.  Here is a link to the Youtube channel of an ex-colleague of mine from UT Arlington where more PDE video clips are available. (The rotating DWE/CDE and supersonic wind tunnel videos are from other ex-lab mates.)

Propulsion is one of my main research interests. In thrust we trust. This blog is a collection of articles on new and cutting edge technologies related to energy and propulsion.

Leave me a note if you find something interesting or contact me if you have questions, comments or something of interest related to energy and propulsion. Thanks for reading. Best wishes.

  2. Technology Submission – Novel Rotary-Turbo-InFlow Tech / Featured Development

    Atypical InFlow Thermodynamic
    Technology Proposal Submission
    Innovative [TURBO-ROTARY]
    Novel (Fueled) Motor Engine Type

    -The Gearturbine comes from the contemporary ecological essential global needs of an efficient power plant fueled motor engine. -Power thrust by bar (tube); air, sea, land and power generation, work use application.

    *Have the similar simple basic system of the “Aelopilie” Heron´s Steam Turbine device from Alexandria, [10-70 AD] one thousand nine hundred years ago. Because; the circular dynamic motion, with 2/Two Opposites power [polar position] lever, and is feeds from his axis center.

    YouTube Video/10.30 min; * Atypical New • GEARTURBINE / Retrodynamic = DextroRPM=> VS to <=front; "Collision-Interaction Type" – inflow vs. blades-gear-move. Technical unique dynamic innovative motion mode. [Retrodynamic Reaction = When the inflow have more velocity the rotor have more RPM Acceleration, with high (XY Position) Momentum] Which the internal flow (and rotor) duplicate its speed, when activated being in a rotor (and inflow) with [inverse] opposite Turns. A very strong Novel concept of torque power thrust. At field explanatory example with a metaphor is like if a sailboat take the wind from his prow front to move; wind/inflow + knots/rpm + wind/inflow + knots/rpm + wind/inflow + knots/rpm + etc… = Acceleration x Acceleration = Exponential Acceleration. Whereas it has more movements forwards, it receives a frontal impulse still but to move more forwards. A present example of the implementation of the Retrodynamic effect is in the application in the accelerator (and collider) of particles that this in the border of Switzerland and France.

    -Shape-Mass + Rotary-Motion = Inertia-Dynamic / Form-Function Wide [Flat] Cylindrical shape + positive dynamic rotary mass = continue Inertia kinetic positive tendency motion / all the complete Rotary motor mass weight is going with the power thrust move circular direction.

    -Non-waste parasitic looses system for cooling, lubrication & combustion; -Lubrication & Combustion, inside a conduit radial position, out way direction, activated by Centrifugal Force-Fueled Injected. -Cooling; a) IN-Thermomix flow, & b) OUT-Air Thermo transference.

    -Combustion 2Two [Inside-Rotary-Dynamic] continue circular [Rockets] flames. Like two dragons trying to bite the tail of the [ying yang] opposite other.-Increase the first compression by going of flow reduction of one big circumference blades going pass to 2TWO reduced, very long distance (total captive compression) INFLOW [inside propulsion] CONDUITS [long flow interaction] [like a digestive system] Start were ends, in perfect shape balance in perfect equilibrium well balanced, like a snake bite his own tale. -4 TURBOS Rotary [inside-rotary-active] [In-Flow, Out-Flow] Total Thrust-Power Regeneration [Complete] Power System. -Mechanical direct 2two [Small] "Planetary Gears" at polar position. Like the Ying Yang Symbol/Concept. Wide out the Rotor circumference were have much more lever [HIGH Torque] POWER THRUST. -Military benefits, No blade erosion by sand & very low heat target profile.-3 stages of inflow turbo compression before combustion; 1)1-Turbine, 2)2-Turbos 3)2-Turbos. -And 3 points of power thrust; 1-flow way, 2-gear, 3-turbine.

    *The most innovative power plant motor engine project today. Higher efficient % percent. Next trend wave toward global technological coming change.
