Human Interface Rotor System Helicopter (HIR) yes....way out in left Field
Permalink  
 


I have received some positive feedback from engineers and pilots. One patent pending for it. Bell Helicopters is taking a look at it, but no promises. DARPA took a look as well as a few others.
Human Interface Rotor System helicopter (HIR) US Patent App. # 12,462,595
www.envisionhelicopters.com

The HIR airframe uses "human interface" in conjunction with an offset axis gimbal joint to "morph" the airframe thereby tilting the rotor disc for directional control. This slightly "flexes" the center of gravity. Charles Seibel was first to design a helicopter with human interface control. The GEN H4 uses a gimbal, yet it is a fixed pitch coaxial design. The HIR system does not have any linear shift in weight / CG.
The Human Interface Rotor System is only a motion and balance physical-interface system in its current configuration. The weight of the pilot is in balance with the rest of the upper airframe aft and distributed between the two airframes. The goal is to combine haptic and physical interface with a computer system that assists with pilot control. The HIR rotor system can then become a platform with an intelligent control system. Our Japanese counter parts are already working with HMI and HAM, but I have not seen it applied to rotorcraft as of yet. I have a few other things not related to rotorcraft that I'm working on....a chasis for an electric car, etc

This looks like a very promising project! I have not seen this kind of concept before and I'm looking forward to seeing how far the project goes later on. Also thanks for the link, I'm reading what I can into it.

Very promising indeed, a very unique idea. Wishing you the best of luck with this project. I am also interested in this electric car chasis you mentioned.

All,

Thanx. I enjoy the stuff that all of you bring up as well. The Japenese GEN H4 uses a gimbal joint system, but it, as well as the Airscooter, use fixed pitch rotor hubs.....no autorotation if powerplant fails. They're still great designs, but I wanted to push the envelop a bit further. The whole morphing airframe came about in an effort so collective pitch could be maintained. Incorporating the pilot's weight and allowing the pilot to move slightly with the rotor system came about so there would be rigid, yet smooth stability when control inputs are made. If you look at the GEN H4 on the You Tube clips, the control stick is really sensitive and I'm not an expert, but I would be concerned about over-correcting. It's been a fun 5 years since I started, but I had CG issues with the mock ups at first, so I went back to the design on computer and finally worked it out. I only get to do this stuff on week-ends so I'm behind on everything. One of the guys who was in Iraq with me got out and is going to Purdue this year. I few years back I had an idea for a "tail rotor failure recovery system. I showed it to him and he has had some input on it, so I made him a co-inventor. I have too many projects going at once but I like mechanical stuff. Godspeed all

Regards,

Dave

Commander31,

The electric car chasis is not something I can patent and I would not want to patent it. The oil industry has cheated the American consumers over enough. Battery technology still needs to imporve. My thinking is this....if an alternator keeps the battery charged and runs all of the electric stuff on board, then why can you not "daisy chain" 3 or more alternators to keep an electric car battery charaged and running longer durations if not indefinately? Back to the battery technology. Right now I think the issue is that the electric drive motor uses more power than an alternator/alternators can replace. We'll see. When I retire from the military, I will build one to see what happens. As well, I well build the HIR helicopter in a single place ultralight...once I finish my tweakingit in the RC scales. Alot of things can change when you up scale to full size. We'll see.

Dave

Comander31,

I'm still tweaking it, but I'm also waiting for battery technology to get better. Even if it's patentable, I want everyone to have for free. The Oil Industry has been buying up patents.....and/or buying people off to prevent technology from helping the American people and putting a dent in their quarterly statements. The American consumer has been cheated enough.

The rear diff needs to be disconnected when using the front axile electric drive

Back on the HIR subject; trying to upload most recent video clip of the CF airframe on You tube. More to follow.

Latest carbon fiber configuration; morphing airframe servo actuation.

Love the morphing action of the airframe.

Failcopter,

Thanx............trying to upload the first CG hang test for this particular airframe. In that clip it has the larger reduction gear and thinner stainless stell mast that bent during a power up from the torque. More to follow.

You are doing a very good work on this unique system, I have never saw a morphing airframe such as the one you are developing before on any rotor-wing platform.

Yak,

Thanks. It's only the first test platform and it does not have lateral control, which means the thrust from the tail rotor will also cause lateral drift. I can negate it a little by tail rotor adjustments to keep it in an orbit. The larger gas powered will be have lateral control as it will use an off set axsis gimbal. This one only has a forward / aft tilting axsis.

Dave

Aluminum airframe mockup w/o control linkages and prior to switching back to the gimbal joint. This mov-clip uses shows a spherical bearing, which may work, but requires the use of the alternate tilt mech.

First center of gravity hang test...........prior to first power up, had a smaller stainless steel mast and larger reduction gear.

RotorwingX,

No problem. I'm juggling a number of projects, all of which are part time. Uncle Sam keeps me too busy to enjoy a regular amount of time experimenting.

New motor...ouch $50 bones! I may need to tweak the CF frame a bit. Any of you tech tweakers know what the blue wire is for? I only do housing and auto wire.

I'm an ammeture with electronics but I learned somewhere that sometimes the colors aren't always a color code and mean nothing. But if I had to guess, I would say it is the negative wire.

The blue wires are generally used for travelers in three-way and four-way switch applications. They also are used as switch legs to things like lights and fans.

Thanx,

I ques I could be called.."3 Wire" because it is goes over 3 wires..........lost without my reg. books

In this case a switch leg to his new motor. Yellow wires are just alike in case you didn't know.

Little over half way through modifications.

And they say the X2 is the future of helicopters. They obviously have not seen Dave's morphing airframe demonstrator yet. Keep up the good work!

Thanx.................if it smacks the wall of my apartment, I'll post the video too....and keep trying.

Supermaneuverable,
Thanx. I have to balance my time for working with it. Going to the filed next week and then home for the 4 day. Might be a couple of weeks until I get the TR & mast bearings mounted. Never enough time.

Dave
