US Army contract to develop a compound helicopter incorporating the Piasecki Vectored Thrust Ducted Propeller (VTDP) concept for the AH-64 Apache and AH-1W SuperCobra is nearing completion. Programme objectives have been met or exceeded by both the AH-64 VTCAD and AH-1W VTCAD configurations, resulting in increased maximum level flight speed to over 370km/h; 50% improvement in longitudinal acceleration and deceleration capability in level flight; 50% decrease in turn and pull-up radius at speeds in excess of 175km/h; and handling qualities that are at least as good as those of the baseline AH-64 Apache and AH-1W SuperCobra. In addition, tactical simulations have confirmed superiority of VTCAD over standard Apache and AH-1W SuperCobra. A separate US Navy contract involves investigation into application of VTDP technology to the AH-1W(4BW) four-blade rotor configuration. The Navy contract also includes ground testing of the full-scale VTDP and additional flight controls simulation and testing of the 4BW/VTDP configuration. Piasecki has also proposed flight demonstration of this technology on an AH-1W(4BW) to the Navy.

this, this thissss can't fly
The back rotor doesn't look like it helps it. They should of used the regular rotor. However, The weapons are excellent. It's based on the AH-1 super cobra.

It's 15 years later now, and this thing has never reached the flying hardware stage. Was it cancelled by budget cuts long ago? Or did they discover some show-stopping technical difficulty with the concept?

ALL I KNOW IS THAT THIS PIASECKI V.T.D.P. COBRA WOULD BE PERFECT FOR MODERN OR FUTURE WARFARE. IT WILL DEFFINATLY GET THE ENEMY SCARED AND RUN!

I AGREE WITH "SUNRISE"! BUT THERE SHOULD BE AN AH-64 APACHE VTDP ALSO.

THIS IS THE PERFECT GUNSHIP!

THE APACHE VTDP CONCEPT IS MISSING
Do you have any comments ?
