Hi does anyone know what kind of fan blade sections the doak vz-4da had? Regards Jacques

I a have photo of the Doak 16 exhaust vanes (for pitch & yaw control in hover)

on time i'm building this plane as rc-model. now i look for pictures from the tail-back side to complete thisone. maybe you can help to me? also i'm intresting on all documents(drawings,pictures)abaut the x-planes.also on built in time: x-13,x-14,x-22 and planed some more others.

This new turbine engine power plant, have the VTOL apliocation:

GEARTURBINE -Atypical Combustion Turbine Engine, -State of the Art, -New Thermodynamic Technology, -With Retrodynamic "Dextrogiro vs Levogiro" Effect, is when the inflow direction moves is against [VS] of the circular rotary dynamic / RPM Rotor Move VS Inflow Conduits Way /ACTION VS REACTION / Front 2 Front / Velocity vs Velocity, making in a simple way a very strong concept of power thrust, a unique technical cuality. -Non Waste, parasitic losses form-function engine system for; cooling, lubrication & combustion; -Lubrication & Combustion inside a conduit radial position, out way direction, activated by centrifugal force (centrpetal to in), -Cooling in & out; In by Thermomix flow & Out by air Thermo transference, activated by the dynamic rotary move, -Increase the first compresion by going of reduction of one big circunference fan blades going to, -2two very long distance cautive compression inflow propulsion conduits (like a digestive system) (long interaction) in perfect equilibrium well balanced start were end like a snake bite his own tale, -Inside active rotor with 4 pairs of retrodynamic turbos (complete regeneration power system), -Mechanical direct "Planetary Gear" power thrust like a Ying Yang (very strong torque) (friendly loose friction) 2two small gears in polar position inside a bigger shell gear, wide out the rotor circunference were have much more lever power thrust, lower RPM in a simple way solution for turbines, to make posible for a some new work aplication (land). -3 Stages of inflow turbo compression before the combustion. -3 points united of power thrust; 1- Rocket Flames, 2-Planetary Gear & 3-Exhaust Propulson, all in one system. -Combustion 2two continue circular moving inside rocket Flames, like two dragons trying to bite the tail of the opposite other. -Hybrid flow system diferent kind of aerolasticity thermoplastic inflow propulsion types; single, action & reaction turbines applied in one same system, -Military benefits, No blade erosion by sand & very low heat target profile. -Power thrust by barr (tube); air sea land & generation aplication, -With the unique retrodynamic technical cuality of "dextrogiro vs levogiro" effect is when the inside flow moves against of the rotor moves making a very strong concept, RPM Rotor Move VS Inflow Conduits Way (an a example is like to move the head to the side of the strike ponch) -A pretender of very high % porcent efficient power plant engine. -Patent; Dic 1991 IMPI Mexico #197187

The fans were fixed pitch. There was no collective type control.

I'm trying to verify that the Doak 16 used only a throttle or throttles for power or thrust control - and not a collective type control.
