lower bearing mount; sizing to mast

4th servo actuation with the changes. Small adjustments here and there. Lower mast bearing mount changed from doubling as the upper motor mount to now being the lower motor mount/lower mast bearing. Couplings are too long for a drive train to spur. Going back to pinion direct to reduction gear, but motor will be about 4 mm lower tha original configuration.

Upper Mast bearing and reduction drive

Upper mast bearing mounted; a few small changes need to be made; not using a power train from the motor to the reduction gear because the couplings are too long.

Rotor Hub

Given the fact that my airframe is a mechanical morphing airframe, I've had some concerns about using a teetering hub due to mast bumoping. I may use an articulated hub with  flapping and lead/lag hinges. More to follow. Godspeed.

Say it ain't So

Once again, thanx to my peers at Stingray's, I've heard through the back channels a tid bit of info that has not been verified. I've inquired with a member at the Vertical Lift Consortium (VLC), but no statements as of yet. What's floating around is that Sikorsky's X-2 was canned this month, but I've yet to see any official announcements for it, so I will not compound the rumor. I had thought that the purpose of the VLC was for the respective helicopter industries to band together because the DOD was tired of wasted money and prototypes that never get fielded, like the Commanche. Let us hope that this does not continue. All of us in the milirary deserve better than what the industry has been putting out lately.

Self-less Service

Most in any industry seem focused only on their "end numbers" with regard to profits. That is the goal of business in general, but now they're out for "self" rather than our nation and economy. There is a vast difference between  who we are in the military and those in the coporate world and how they conduct business.
Imagine if every business only implemented just a little "self-less" service. I'm certain even just a small amount would have prevented all of the "out-sourcing", employee layoffs, and down sizing. Nice going all you folks in the upper echelons of coporate business.............keep cheating us. Now it's starting to back fire on you a bit. You needed the government to bail you out because you thought that out sourcing your manufacturing would turn more profit. Now you have to pay to have your products sent back to the states and since the parts were made overseas, the crafstmanship went belly up. Like Maytag............not many want to purchase their products. Their parts repair service is substabdard and at times the parts are so poorly made, they do not even fucntion with the model it was originally designed for. Way to go. Levi Strauss is right up there with the rest of them.

Lower mast bearing mount upper motor mount

Got the new motor mounted on the lower mast bearing frame/mount. Still working on the shot drive train from the motor to the reduction drive spur gear.

1st, 2nd & 3rd mod.

This is the difference between 1st, 2nd & 3rd Modifications. Battery and mixer are lower on 3rd mod. shown w/o canopy. Some changes to morphing arm and tail boom as well

lastest progress

I need to purchase a different size of flange bearing and find 4130 chromoly tubing small enough to help cut weight. Pic below is lower mast bearing/ upper motor mount. I'm a little behind.

Industry and Innovation Cont.

Independent inventors of genuine character push themselves with regard to creativity and continued innovation. They're not pre-occupied on profit because they're just doing what they love to do. Problem solving. On week-ends in their garages, basements or “man caves“...and women being just as smart, I'm certain that there are some inventors who have a "woman cave" to build and create. We've gotten so twisted around the axle about just helping "self" that once we get there, we forget the others who stand where we once stood. And as we lturn to walk away, one question should come to mind; when we look away in the interest of self or a larger quarterly statement, are we closing the door on new innovation that may become the next to benefit the whole?

Cold Shoulders

Often it seems that select in the industry will give a cold shoulder to an idea. Lets take a quick look at ideas.
In 2003, the Space Shuttle Columbia disintegrated in the atmosphere from damage to the heat tiles during lift off. In contrast to the concept of using heat tiles on space vehicles, Burt Rutan proved in 2004 that
outside the normal approach is not the wrong way, launching a vehicle into space and designed the craft to return back into the earths lower atmosphere without the use of a heat shield and without burning up from
air friction. The platform design was outside the normal concept approach to space flight. Had NASA every considered Rutan’s concept? If not, why? Is it because the origin of the idea and respective proprietary rights did not come from within the organization? Why should this matter to anyone? We all benefit as a whole. Does the organization believe that they will not be considered "competitive" if they pursue an idea that did not come from within their organization?

Industry and Innovation

Every significant change in our Nation was brought about by someone
who thought outside the normal axiom of creativity and innovation.
Those who tinker in their basements and garages. Take for granted
a serious thinker who is mechanically inclined & see what
happens....money or not.
Invention can be an individual endeavor.
The innovation required to perfect an idea that will benefit the
whole may require a collective effort, yet it is not out of the
reach of the individual to move from invention to innovation.
