This blog will be covering the advancement of military technology of the past, present, and future through videos, photos, and written articles. It is our hope that anyone who reads this blog will gain a greater understanding of military technology and the ethics behind it's research and deployment.
This is a really cool video, and yes that helicopter does look extremely weird. It seems however that the pilot is having problems controlling the helicopter. It kind of looks like it flies more like an airplane and lands like a helicopter. I'm not sure what advantages a design like this would give. Maybe it is more efficient than its predecessors. Given the name of the title I'm assuming that it is an extremely fast helicopter, but I would have liked some additional information on it.
I would have to agree with the comment above. Check out: http://en.wikipedia.org/wiki/Piasecki_X-49: For more information on this "weird helicopter".
"The Piasecki X-49 is a four-bladed, twin-engined, experimental compound helicopter under development by Piasecki Aircraft. The X-49A is based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and includes the addition of lifting wings. The concept of the experimental program is to apply the VTDP technology to a production military helicopter to determine any benefit gained through increases in performance or useful load.
"Speedhawk" is a concept aircraft[1] based on applying X-49A compounding concepts to a production UH-60 Black Hawk offering better performance, range, and increases in useful load. The "Speedhawk" aircraft includes an SPU (third engine), high forward-swept wing concept, a 45 inch cabin extending fuselage "plug", and several other drag reducing and performance-oriented improvements, including a rotorhead fairing, landing gear streamlining, and a fly-by-wire flight control system."
We, The Captains of Industry, hereby agree to complete assignments in a timely manner, work together as a team, and do our best to achieve success. If any issues arise, we will communicate amicably, and only in extreme situations we will request the assistance of our teachers to dissolve a dispute.
