We had a great time doing slalom testing of the Switchblade ground prototype! Our 700′ course was set up with eight cones spaced 100′ apart, per the standards of the Road and Track slalom testing procedures. The Switchblade has a long wheel base (distance from front to rear wheels) and as such rides very smoothly. […]
Final results from the wind tunnel were received, with expected (very good) results! The big news was that our drag (resistance through the air) dropped 7% with the new tail. This is tremendous, as after our first wind tunnel testing we found that we were already below our drag predictions. We did not think we […]
The wind tunnel testing at the University of Washington in Seattle was finished last Friday to good result, with the initial results showing that the final tail design produced significant increase in stability. Willem Anemaat of DAR Corp, our aerodynamic team, was happy with the results. As per last time, the numbers need to be […]
The Suzuki Hayabusa engine in our ground prototype is running! It took a lot of dedicated work by our build team, but the motor started up and sang a very pretty note after over a year of not being run. The wiring was quite a hang-up for quite a few days, but we went back […]
While the wing structural engineering and mold drawings are being accomplished, the Samson build team turned their attention to getting the ground prototype back up on its feet. We are taking test components of the suspension and drive train and testing them in the real world prior to installation in the fuselage (body) of the […]
You may have heard mention of the wind tunnel model that Samson tested in the University of Washington wind tunnel recently. I thought I might show more photos of that model and process, as it was certainly an experience. The wind tunnel staff were well trained and in control of every aspect. It was very […]
On Thursday we wrapped up our Switchblade wind tunnel testing at the University of Washington in Seattle and are waiting for the final results. One thing that surprised us was that the body, or fuselage, of our 1/4 scale model contributed to the overall lift in an unusual way. Typically wings provide the lift for […]
The torsion bar front suspension has been assembled and integrated with the steering, brake and wheel for the front assembly. With some minor tweaks it will be ready for mounting in the ground test vehicle shortly. The weight of the torsion bar system was much higher than spec’d, so we will be testing for function […]
The wind tunnel model is almost complete! One of our team members Ron Birch is shown sanding down the white oak test model. Here is Ron starting to paint the model a very nice pearl color! After sanding and painting here is our pearl wind tunnel model. We received three sets of front torsion bar […]
Our wind tunnel model is coming along, with one of the aluminum wings shown above. This is a nearly finished surface, with an unfinished surface shown below. The wind tunnel model is being done as a triple check on the low-speed flight characteristics of the new box tail. The body of the wind tunnel model […]
