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. www.kulikov.com

this, this thissss can't fly | 1337painless, 08.03.2011 | reply |
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. | deaftom, e-mail, 14.04.2011 | reply |
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? | <0>, e-mail, 10.03.2009 | reply |
Interesting.

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! | "SUNRISE", e-mail, 25.11.2006 | reply |
I AGREE WITH "SUNRISE"! BUT THERE SHOULD BE AN AH-64 APACHE VTDP ALSO. | SUNRISE, e-mail, 25.11.2006 | reply |
THIS IS THE PERFECT GUNSHIP! | "STINGRAY", e-mail, 26.01.2007 | reply |
THE APACHE VTDP CONCEPT IS MISSING |
