Quite true. And the X-29 engineers discovered this pretty quickly.There will be some limit beyond which the motors and actuators are incapable of responding fast enough.
Neutral point is near 1/4 chord. For a biplane like this with equal? size wings, it's 1/4 of the way between the 1/4 chords of the wings.Given that the operator's head is about mid-ship, his/her CG (about at the navel) is forward of the mid-point of the vehicle. Means the overall CG is probably slightly forward as well, giving it a small positive static margin.
Seems a bit awkward. I know you have very limited experience so you might not be able to elaborate more.It had a typical joystick for pitch and roll that was normal. It had sort of a coulee hat button on top of the stick that controlled throttle/altitude. Normally that would be pitch trim, so my helicopter experience prevented me from operating it correctly in the 60 seconds of sim time I had. (long line of kids waiting).
Hence my "designed by industry outsiders" comment.
Had a chance this evening to sit in a quiet room with a cup of very good Darjeeling. Realized this is kind of a dumb question. All six degrees of freedom use the craft as reference except altitude/vertical. It's the only one that needs to use earth as the reference?Horizontal flight control should also be pretty easy to duplicate but how do they handle the transition?
Yup, surprisingly sizey, see how small their heads are in the videos.Its a lot larger than I had expected based on the raw dimensions+.
Are you thinking of Accelerometer or Accelerator? An accelerometer measures the rate and direction of acceleration, including the force of gravity. An accelerator is a control that makes you go faster.Millions of cars have them, and have had for years.
Obviously not the same, just pointing out the basic tech is very common and well sorted.
Any airplane or seaplane or ultralight or helicopter could operate below 50 feet if allowed. I haven't heard of any 50 ft rule.I have another can of worms. BF can operate at 50 feet agl and below for an entire flight. It could even follow terrain while maintaining less than 50 feet agl. Think WIG but not limited to relatively flat terrain or water.
In class B or C airspace that starts at the “surface” with the surface in some parts of said airspace being navigable waters, can a WIG legally operate? Watercraft of sizable height can operate within a few hundred feet of the runways at KSFO. What I’m wondering is does the FAA care about vehicles that don’t “protrude” above 50 feet agl.
I haven’t either. Supposedly WIGs are regulated under maritime laws because they operate on and within (50 feet?) of the water? Supposedly the FAA hasn’t ruled on WIGs operating over land because no one has tried to register one? I am just wondering if airspace designated as starting at the “surface” means the actual surface or is there a buffer of say 50 feet.Any airplane or seaplane or ultralight or helicopter could operate below 50 feet if allowed. I haven't heard of any 50 ft rule.
