Kaveri Engine Undergoes More Flight Trials In Russia

SOURCE : AviationWeek.com
India’s Defense Research and Development Organization (DRDO) and Russia’s Gromov Flight Research Institute (GFRI) have conducted more flight trials of India’s Kaveri engine on a modified Flying Test Bed (FTB) IL-76 transport aircraft.
Mohan Rao, director of the Gas Turbine Research Establishment (GTRE) in Bangalore, told Aviation Week that flight data analysis from the first flight on Nov. 3 was submitted to GFRI officials, who presented a detailed report to Russia’s Ministry of Industries.
“Based on this report, we got the clearances for further flights. We had the second flight after a week for more than an hour in very similar conditions to the first flight,” Mohan said. “The engine was inspected again and all flight parameters were analyzed. During the second flight, we went up to 5 km. at 0.6 Mach and 4 km. at 0.4 Mach. We need to study the engine data and combustion stability.”
GTRE officials checked close to 50 test points, including low Mach number, low altitude, and high altitude. In one test, the Kaveri was on switch-off mode while the IL-76 took off to check an “inflight windmill” start.
“The engine was ignited [in] midair at windmill speeds and it was a success. We also had an ‘altitude relight’ to evaluate the engine’s restart capabilities. We had so far a total of three flights,” Mohan said.
DRDO plans to conduct nearly 60 test flights in the next couple of months to gauge engine reliability, safety and airworthiness.
“Now we will try out different Mach numbers and at different altitudes. The engine will come back to India after five months so that we can carry out further tests. We are aggressively conducting the flight-test campaign,” Mohan added.

  1. Technology Submission - Novel Rotary-Turbo-InFlow Tech - Featured Development

    GEARTURBINE PROJECT
    Atypical InFlow Thermodynamic
    Technology Proposal Submission
    Novel Fueled Motor Engine Type

    *State of the art Innovative concept Top system Higher efficient percent.
    Have similar system of the Aeolipile Heron Steam device from Alexandria 10-70 AD. -New Form-Function Motor-Engine Device. Next Step, Epic Design Change, Broken-Seal Revelation. -Desirable Power-Plant Innovation.

    YouTube; * Atypical New • GEARTURBINE / Retrodynamic = DextroRPM VS LevoInFlow + Ying Yang Thrust Way Type - Non Waste Looses

    -This innovative concept consists of hull and core where are held all 8 bteps of the work-flow which make the concept functional. The core has several gears and turbines which are responsible for these 8 steps (5 of them are dedicated to the turbo stages). The first step is fuel compression, followed by 2 cold turbo levels. The fourth step is where the fuel starts burning – combustion stage, which creates thrust for the next, 5th step – thrust step, which provides power to the planetary gears and turbines and moves the system. This step is followed by two hot turbo steps and the circle is enclosed by the final 8th step – bigger turbine. All this motion in a retrodynamic circumstance effect, wich is plus higher RPM speed by self motion. The Reaction at front of the action.

    *8-X/Y Thermodynamic CYCLE - Way Steps:
    1)1-Compression / bigger
    2)2-Turbo 1 cold
    3)2-Turbo 2 cold
    4)2-Combustion - circular motion flames / opposites
    5)2-Thrust - single turbo & planetary gears / ying yang
    6)2-Turbo 2 hot
    7)2-Turbo 1 hot
    8)1-Turbine / bigger

    -With Retrodynamic Dextrogiro vs Levogiro Phenomenon Effect. / Rotor-RPM VS InFlow / front 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 torque power concept.

    -Non waste parasitic looses for; friction, cooling, lubrication & combustion. -Shape-Mass + Rotary-Motion = Inertia-Dynamic / Form-Function Wide [Flat] Cylindrical shape + positive dynamic rotary mass = continue Inertia kinetic positive tendency motion. Like a Flywheel.

    -Combustion 2Two continue circular [Rockets] flames. [ying yang] opposite to the other. – With 2TWO very long distance INFLOW [inside propulsion] CONDUITS. -4 TURBOS Rotary Total Thrust-Power Regeneration 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. -No blade erosion by sand & very low heat target signature profile. -3 points of power thrust; 1-flow way, 2-gear, 3-turbine. *Patent; Dic. 1991 IMPI Mexico #197187 All Rights Reserved.
