I am creating this blog to document the building of my first full-scale unmanned aerial system. As an aspiring aerospace engineer, I am seeking a practical, hands-on building experience that surpasses kit-model building and multicopter work that I have done in the past. It is my hope that this project will provide insight into every facet of the engineering process, from inception through a maiden flight. As a project, the K-1 is intended to bridge the gap between my experience in RC model/multicopter building and flying, and my fascination with commercial/military unmanned aerial systems. The K-1 will be a low/medium altitude, low airspeed, and high endurance unmanned aerial system as a prototype for surveillance, security, and surveying (in theory).
To be consistent with the convention of naming aircraft after birds of prey, I am naming this UAV the Kite (all the cooler names [falcon, raptor, etc.] were taken).
So far, I've purchased a 33cc gas motor and associated accessories as well as bulk epoxy (West Systems 105), carbon fiber cloth, CF tubes and sheets.
The wings will be 5.5 ft long each, with a 25% taper on the outer third of each wing and a 2° dihedral angle. They will be 3D printed, covered in carbon fiber/epoxy and supported from the inside by CF tubing. See above.
(I'm still working on these)
Besides the aforementioned corporations, Gisela and Joe Noci's blog has been quite helpful in determining my airfoil choice (S7075 [as an improvement over the Clark-Y]) and wing construction methodology.
Since it is my first build, the K-1 will be far from optimized, but I've got the whole summer to build the K-2 and K-3. It'll be the proverbial first pancake that is always burnt.
