About Us


Our Beginnings

During early experimentation, the focus was on mechanical wing designs meant to mimic bird and insect flight. The direction of the project changed when It was discovered that a propeller system mated to our unique cam design had more practicality and potential. One reason for this was the understanding that a rotating configuration can mimic a bird or insect wing without the momentum loss caused by the back and forth motion of flapping. The project evolved into the discovery of new types of vertical take-off and landing (VTOL) concepts and a unique counter measure for retreating blade stall in helicopters. 



Inventor and aviation enthusiast, Cary Zachary has over 20 years experience with new product development. He founded Blainjett Aviation in 2016 with the confidence that he had something significant to contribute to the aviation industry. He immediately began filing patents and building prototypes with the help of some local experts and long-time associates.   

Keith Hertzog is a retired Vietnam war veteran and combat engineer who spent time in the old Huey helicopters. He has 30 years of experience with flying RC helicopters and quadcopters fitted with long-range guidance systems. He is also a retired automation engineer and inventor.


Thrust Vectoring Prototypes

Our Version (V1a) thrust vectoring prototype was intended to be a proof of concept. We created a test stand around it and gathered thrust/watt data and showed that we could vector thrust in any direction through pitch control inputs. Our Version (V1b) did the same thing while improving efficiency with less moving parts and a 50% weight reduction.


Scaled Helicopter Retrofit

After some mentoring from experts in the aviation industry we discovered more applications for our technology.  Dissymmetry of lift and retreating blade stall are main limiting factors in the top speed of a helicopter. Since our cam could more effectively retain higher pitch angles on the retreating blades without going into a stall while holding lower pitch angles on the advancing blades, it was obvious we had something unique for the helicopter world. We were very excited about this potential game changer for the industry and decided to build a scaled helicopter with our cam as a proof of concept. So far a 75% improvement has been shown with our early bench top testing compared to a swashplate.  


Next Steps

Our goal is to share this technology with engineers, inventors and manufacturers who would use it to gain an advantage in their respective markets. We believe this technology is scalable and potentially disruptive to multiple categories of aviation. Patents are either allowed or pending in the US and abroad while proof of concept prototypes are in the works. 

As we navigate through the early stages of development, we look forward to working with other like-minded individuals that are interested in taking this exciting journey with us.
