What's new

Is this the US Army next generation superchopper

the two fans on the sides need to change its orientation to keep it hovering.

Not exactly, they can just shut it off to hover with the two counter rotating blades.

What IF a single anti air weapon takes out 1/6th of the US defence budget in a single go?

Are you mentally challenged, ya koi special course kiya hai?

Eh...doubt we'll see this in the future.

The US already had a next generation attack heli platform...it is called the RAH-66 Comanche. The project was cancelled however and the funds were later spent on developing UAVs and UCAVs.

I'm going to have to agree. It is unlikely they are going to budget this thing.

counter rotating blade is not a simple design, plus it will take the time to shut them down and then start the reverse , etc etc, with new fuel lines.

Coaxial rotor systems are recognised as being more stable, more robust, safer, faster and quieter than traditional helicopters. They are a mature technology that have been produced by established companies, notbaly Kamov, Sikorsky, Gyrodyne. With the advent of UAVs and UCAV there is a resurgence of interest in coaxial rotor systems. These system's inherent stability and quick control response make it suitable for use in small RC helicopters. These benefits come at the cost of a limited forward speed, and higher sensitivity to wind. But it's not just of interest for 'small' applications. A principal disadvantage of the coaxial rotor design is the increased mechanical complexity of the rotor hub. More moving parts and complexity mean the coaxial rotor system is more prone to mechanical faults and possible failure. Also, coaxial heli's are more prone to the "whipping" of blades and blade self-collision, at least according to its critics. This is where the challenges lie.

The Sikorskyu S-69 which has forward thrust provided by two turbojets and allowed the main rotor to only be required to provide lift, demonstrated good hover stability against crosswind and tailwind. With jets installed, however, it lacked power to hover out of ground effect and so for safety reasons used short take of and landing. A wing is needed for high speeds and to improve maneuverability. Another challenge for the proposed helocoipter with ducted fans is to get an engine that is light but has sufficient power (about double the output of the UH60's engines)
