Tilt rotor/SLT hybrid

Posted on February 21, 2017 at 10:46am 6 Comments

Separate lift/thrust systems are growing fast in popularity, to the point that there are already a variety of commercially available systems.  They seem to be the future and continually get better.  Thanks to our developers, Ardupilot has some great features like holding position with forward thrust and is becoming very good at leveraging the benefits of an SLT system.  These…


Static thrust optimized EDFs

UAS Vision published an article on these EDFs optimized for static thrust.  Something I am constanly googling around for but never seem to find...

"The pan-European Neva Aerospace consortium, which is developing heavy-duty drones, industrial and commercial unmanned aerial systems…


Helicopter Concept

Posted on November 22, 2016 at 3:25pm 16 Comments

Hello everyone, I have posted about this idea before in the form of an aircraft which could transition between vertical and horizontal flight.  While I believe it is possible, especially in the form of a flying wing, the response I have received from this site as well as other sources indicates that most observers have serious doubts.

I have decided to focus on…


Monocopter Concept

Posted on October 15, 2016 at 6:20pm 7 Comments

Hey everyone, I would love to get your opinions on this concept...

I am working on a rotary wing design, and this is a monocopter version of it.  It has only two moving parts, the two propellers.  The two props drive the wing around an avionics hub while also controlling the pitch of the wing throughout the cycle through differential thrust.  The battery…

Nice things on your blog! 

Yes we got the comments, but that is OK. if you have no experience, you might worry. Think your little 4 prop plane is interesting!

Hi Joe, great design.  What software did you uses to animate?

Good to know, Joe.  I worked on a related idea several years ago.  The intent was to transition from a quadcopter to a flying rotor.  Essentially a free rotor (the helicopter equivalent of a flying wing) that would uses the torque and thrust from one set of motors to drive the entire air frame.  The unused motors could be shut down to conserve power.  The fuselage would be a symmetrical tube hanging from the rotor hub and spin with the rotor. Video would be captured with a wide angle fish eye lens.  The video would then be synchronized with the rotation speed to provide imagery at any point within the field of view.  The whole vehicle would fold down like an umbrella for storage in a hardened tube.

Sorry, no pics as I didn't pursue the idea to a full build.  The cyclic was going to be controlled by the servos that rotated the wing/arms from a vertical to horizontal position.  As the rotor rotated the servos would be synchronized to change the angle of attack of their respective blades opposite the intended direction of travel.

Servo actuation has been shown to be consistently quicker than differential thrust.  One of the benefits of using servos in the rotor hub is that you are able to ditch all the mechanical linkages that can be pesky and transition to a "fly by wire" hub.
