Arbiter Posted July 22, 2009 Share Posted July 22, 2009 Hi Folks, I wanted to solicit some feedback on my project so far. Let me tell you a little bit about it first: 1. This is an entirely new Design. I am starting from scratch at the preliminary sizing level. I am not sure if it will be a conventional configuration or a Canard. I am leaning towards conventional, but have not made the down-select yet. 2. This aircraft as it stands now is 2-place tandem made from primarily composites with 1000lb useful load (2 place @ 325 Lb each + Bags and Fuel for 700+ nm Trips). This puts it at about 3200 Lb Gross Wt fully loaded. This is an aircraft for larger people. The thought with 325 Lbs is the airplane could be re-configured and widened eventually for 4 "regular" 170 Lb individuals (Decrease in the already ample baggage load to make up the difference in weight). 3. One simple design Philosophy. Visibility with speed and utility. Based on aircraft I've sat in I have almost always been dissapointed with the visibility, especially the passenger. I hope to solve this with my design while maintaining high cruise speed (150 Kts) and ample range. Now that I have given you a quick background on Project Endeavour, I have a full-scale cockpit Mock-up in the works. Below are some pictures I would like feedback on. One thing to keep in mind is that none of the dimensions with the exception of the 22" seat width and the minimum 36" cockpit width have been fixed. Enjoy, and I look forward to the feedback you have! Panel 1: This picture shows the over-all cockpit architecture. Notice the stadium seating arrangement. This is much like the BAE Hawk and Apache Helicopter. At this point the pilot is still sitting in the bottom seat, but I have been debating whether or not to place the pilot in the back... Either way, visibility will be un-obstructed. In the middle where the front seat-back is located will be a roll-bar. It is likely this will form a brace for the canopy and will be placed such that the rear passenger has a relatively un-obstructed view. The seat pans are 15 degrees up from horizontal, and the seat backs are 120 Degrees. There is a horizontal portion behind each seat I am planning on bolting the restraint systems to, though this may not be necessary and would save precious space if the shelf could be eliminated. Note: The second deck will have an instrument panel of similar size, but will likely have one single display. Panel 2: Shows a view looking down from the second deck (Though this is not necessarily what the passenger would be able to see). The dimensions show where the 22" seat width and the 36" total width are. I have an old Apache style military grip (Planning to use infinities with the hat switches on my actual sticks) approximately where the side-stick will be located. The cup represents the throttle quadrant (Sweet lever huh ). When I measured the angle the instrument panel makes with the horizon from my eye level I should land somewhere between 18 and 20+ degrees nose down (Depending on seat cushion thickness). This will give great forward visibility if some other design constraint doesn't knock the nose out too far! Panel 3: This is where I hope to get the most feedback. I am looking to build this aircraft within the next 10-15 Years ( This is not a hard time-line, afterall, this is a hobby) so projecting what avionics will be available is hard, to say the least. However, I believe Dynon is here to stay, and they are going modular, which is what I like. I am planning on having an auto-pilot and electric trim, and a completely glass cockpit capable of IFR. My panel philosophy is this: -Maintaining control whilst pushing buttons is a must. Therefore, all buttons that may need to be pushed in most regular flight conditions, and those critical in the most common emergencies will be located such that I can use my throttle hand to operate them while fully seated. -My main display will show and artificial horizon, Vertical speed, altitude, and airspeed. Com info, and a heading tape at the top would also be sweet but I am not sure if Dynon has this yet. If not, possibly an HSI at the bottom. The second display on the right will be dedicated to navigation and will serve as a back-up to the primary and vice versa if necessary. Also at the same level will be the engine monitor on the left. -The left hand side will be where most of the switches and buttons are located. I am currently planning on using those cool Aveo Technology button stacks. The gear lever will be likely placed near the left side as well. -The right side will be where the circuit breakers and Anunciators are. I will probably put the breakers on the side wall in front of the control stick since that will be easier to get to while seated with my back against the seat. I am looking for ideas on how to reduce pilot work-load. I am planning on trying to utilize the stick mounted buttons as much as possibe (Electric trim, Comm, Xponder, Etc...) Speaking of transponders: I am hoping that more companies will offer remote mounted GPS receivers, Transponders, and Nav Comms, because I want all that info displayed on the Dynons eventually without the equipment taking up extra panel space. I think this will be a direction industry will take. If not, then the panel space will dwindle accordingly. NOTE: Speaking of sidewalls... There are none at this point. I will be adding them as I develop the shape of the canopy. They will probably stick up at most 6 inches from the panel interface... Panel 4: This panel just shows the side view more closely. The panel is approximately 38.5 inches from the middle bulkhead. Thank you for looking at my long post. I hope to invite some good discussion about my panel layout and the mock up! I'd be happy to answer any questions that I can at this point about my project! Thank you! -Chris Zupp Quote Chris Zupp ~Aircraft Designer~ Preliminary Design Sequence I: Project Endeavour Aeronautical/Mechanical Engineer Private Pilot Link to comment Share on other sites More sharing options...
