The Indian government today provided a comprehensive update on the indigenous Kaveri turbofan programme. Here it is, in full:

(i) All major engine sub-assemblies have been tested for aerodynamicperformance and structural integrity (life & safety) requirementsfrom qualification point of view.

(ii) Critical sub-systems have been developed.

(iii) Full authority Kaveri Digital engine Control System (KADECS) has been designed and developed.

(iv) Various critical technologies in the fields ofinstrumentation/measurement, health monitoring, data acquisition, etc.have been developed.

(v) Twelve materials (Titanium, Steel and super alloys) have been developed and type certified.

(vi) Directionally Solidified (DS) casting technology and hightemperature tip brazing technology for the High Pressure and LowPressure turbine blades & vanes have been developed.

(vii) Adequate manufacturing technology base has been established.

The reasons for the delay in developing the said engine are as follows:

(i) Non-availability of critical materials, viz., nickel and titanium based alloys in the country............The matter is now solved for the news says..................." Twelve materials (Titanium, Steel and super alloys) have been developed and type certified "

(ii) Low priority from foreign manufacturing agencies in view of theMinimum Order Quantity (MOQ) vis-à-vis the production order quantityfrom other engine houses.

(iii) Lack of manufacturing infrastructure for critical components.

(iv) Flying Test Bed (FTB) trials were not originally envisagedbut included subsequently, based on the recommendations ofCertification Agency and IAF.

(v) US sanctions imposed during 1998 affected the delivery of critical systems & components.

(vi) Lack of infrastructure of engine testing and component / systemlevel testing within the country leading to dependency on foreignagencies.

Kaveri engine testing under simulated altitude and forward speedconditions during February 2010 has been successfully completed.Another engine has been integrated with IL-76 aircraft at Gromov FlightResearch Institute (GFRI), Moscow for ground and flight test which isexpected to complete by October 2010 (sic). These two major milestoneswould make 'Kaveri' engine certified for flight operations. Productionsof LCAs are, meanwhile, as decided by user, being fitted with importedengines.

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

    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.
