Exactly true. Other forums using the same or similar software have the same problem. You can turn off smilies, but, as far as I know, only for the entire post.If expressed as a fraction (which I guess it isn't in reality) you'd get L/D but expressed as a ratio the forum software sees a colon and an upper case D and turns the latter two thirds of L : D into a smiling face... I assume.
bmcj:Then build a plane for a carrier, you can't handicap a design with carrier or VTOL capabilities and still call it an air superiority fighter. The whole one-size-fits-all approach is misguided. [/RANT] [/THREAD DRIFT]
I think so. On any multiple winged airplane the farthest aft wing is the horizontal stabilizer. On a tandem AKA "equal area canard" the H-stab is simply much larger than it needs to be. Since to be stable the aft surface must operate at a lower coefficient of lift than the forward surface there's a lot of wasted area in a tandem.I wonder if the difference is simply wing loading?
OK, so load the aft aircraft heavier than the front one and then slow to minimum control speed. The aft aircraft will stall before the forward one and upset the apple cart. In physics, there is no free lunch. One technique that is typical is to make the system so complex that it is difficult to understand and figure out what is happening. Go back to the basics to determine if the proposal can work.What if you had a long fuselage with an entire airplane at each end. That means a wing and tail at equilibrium (trim). If you had that as a tandem you could basically load the fuselage anyway you wanted and you could control the lift at each end and each end could be kept trim and not stalling. So what I am talking about is basically a freewing setup at each end. That could allow a HUGE range of CG locations for the payload and it would allow flaps on each wing. It would take a computer or another trim control to manage the AOA of the fuselage I would think.
Since the aft wing is fulfilling the function of the H-stab letting it float freely would have the same effect as letting the tail of a conventional float, would it not?If only the aft wing on a tandem was a freewing, could you get away with loading them equally so as not to waste wing area?
