Warren Blazenski, a machinist in Central Oregon, is carving metal for us, producing the wing root metal pieces for attaching the wing to the swinging wing structure. Shown is work on the hinge beam. This is the piece that the wing hinges on to swing in and out, and is kept small by being mostly […]
We tested lighting configurations using the wind tunnel model. Almost all of our lighting will be LED, so we used LED lights of appropriate size to simulate the effects on the model and environment at that scale. We found that the side lights were useful and helped present the size of the vehicle to oncoming […]
Our final part of the drag cleanup on the rear quarters of the vehicle included running the whole vehicle through CFD (Computational Fluid Dynamics) to check airflow and that we haven’t created any adverse pressure zones on the vehicle sides. We also re-checked the airflow through the duct to ensure that the propellers were getting […]
We bolted the hinges to the main wing so that we could test-fit the ailerons and flaps prior to bonding the ribs to the lower skin and spar. To do this we had to temporarily bond ribs in place to reinforce the hinges, and drill holes for bolting the hinges to the wings. Above, Ron […]
While the steps below are being done at Samson for the prototype build, you should know that the Switchblade kit will come with these steps completed. In fact, the majority of the wing assembly will already be completed before you receive your kit. One way to keep an assembly that we are bonding with adhesive, […]
We had the aluminum pieces made that act within the wing to transmit the pilot’s input into the aileron movement, which banks the aircraft left and right. This is called a bell crank (don’t ask me why!). Above are the pieces before treating with an anodizing finish, and below you see them after the treatment. […]
The wing parts and lower wing molds (used to hold the parts in proper shape) were unloaded at the Prineville facility with the help of Composite Approach staff. The molds are very heavy, being of solid wood. The table shown was leveled with the use of surveying equipment to ensure it was dead flat, and that […]
We are getting ready for the assembly of the main wing. As shown in the image below, the main wing has four ribs: one at the wing tip, one between the ailerons and the flaps, one in the middle of the flaps, and one at the wing root. The ailerons are the small movable wing […]
After finishing the left and right wing skins, the molds were made for the wing spar, or main beam. This is the main spar mold for the wing and runs lengthwise along the middle of the wing. There is a secondary spar that is shorter and thinner that will be done next after these spars […]
After finishing the flaps, we have moved on to the main wing. The left main wing skin molds have been carved, along with the fixtures for holding parts in place for later assembly. Below is seen the molds nearly ready for laying in the carbon fiber and core material. This is probably the single largest piece […]
