CASA has published a discussion paper for AUS Airworthiness.
The points of discussion were quite wide ranging and will have an impact of many sectors of the UAS industry. We have tried to place a focus on elements that may become appropriate for CoaX Helicopters.
The smallest player on the field was our 20′ single place Experimental helicopter. But we received a great deal of interest. Here are a couple of shoots at the venue in Maroochydore during RotorTech 2016.
CoaX Helicopters was invited to display and present at RotorTech 2016 courtesy of the Australian Helicopter Industry Association , AHIA.
We had allow a month to manufacture the H37 engine mounts, configure and fit the MoTec and G3X displays, build a new console and prepare the 20′ helicopter for departure.
But not everything goes according to plan! A number of hurdles were thrown out to challenge us and it wasn’t until 6 days before we were due to leave did we receive the engine mounts. Without those we would have to cancel.
On Sunday and Monday we fitted the engine mounts and engine
On Tuesday we collected the MoTec C187. Fortunately the engineers at MoTec had gone above and beyond to load the display data and configure the electrical system to power the display.
On Wednesday all players gathered to pull it all together. Jim Azar worked all day mounting and wiring the Glass displays and finally we had power on the machine
The console to hold all of the components together arrived at 5 pm Wednesday. The panels we still in pieces and had to be fitted.
By 9 pm that night we finally had a finally had the helicopter on the trailer ready to go.
After an extended period of evaluation and numerous delivery delays our new Hirth H37 engine has arrived.
Hirth have produced two stroke engines for over 100 years and we are very confident with the expected results. They are now a preeminent manufacturer of unmanned aircraft engines so we may be able to fit the Hirth to both our manned and unmanned helicopters.
Having 20% more power and 50% lighter than the original Porsche engine it replaces, we expect a significant improvement in the performance of our 20′ helicopter.
Franco Fornasari is in charge of the SolidWorks Creation Project. His work is of an exceptionally high quality and will greatly enhance our capability to integrate with our autopilot provider, perform engineering test in a virtual environment, look at alternate designs for CoaX and continue with our R & D projects.
As discussed in the previous AGM, it was vital for us to reconcile all of the CoaX technical drawings with those parts that were actually incorporated on the most recent example of the 20’ helicopter. To do this effectively it was necessary to completely disassemble one 20’ helicopter down to the last nut and bolt. This task was also critical to allow us to proceed with our R & D into the gearing systems of the CoaX mast and transmission.
As it turned out there were significant differences. Franco has meticulously checked almost every component of the 20’ system and created from scratch those drawings which were different to the paper drawings. Once the drawings are complete we will need to make some engineering adjustments to ensure the helicopters are suitable to take to market. This will include raising the skids to prevent accidental injury from rotating blades.
Fortunately SolidWorks will enable us to look at the changes and determine if they are appropriate from an aerodynamic and engineering perspective.
Dedicated Engineering Skills now available
Jim Azar has raised his hand to become the manager of Engineering Projects. Jim has quite a lot of both engineering and IT skills. This combination will help CoaX move forward with a far wider skill set than we have seen before.
