Why are many Canard designs (Cozy , Eze's etc)
parked with their noses resting on the ground? Is it simply to reduce wear on the Nose gear or for a more esoteric reason? Cheers Steven |

With the nose on the ground it becomes almost impossible for anything but a
near-tropical-storm-force gust of wind (or higher) to move the airplane. "Steven Johansen" wrote in message . au...

The reason is because on those designs the static Cg is only slightly ahead of the main landing gear. Without the pilot aboard there is a very real risk that a gust of wind will tip the aircraft back onto its butt. Collapsing the nose gear when parked shifts the Cg forward. The next question you're going to ask is "why don't the builders move the main landing gear aft?" Two possible reasons: moving the gear aft might make unsticking/rotation on takeoff a much too exciting event (think uncontrolled stall on takeoff), and the main gear has a tendency to throw up runway debris which we'd rather not have pass through the propeller disk.

That would solve a lot of problems with small pushers. Bill Daniels |

Another may be that if main gear is moved aft a more heftier
front NG would be needed. Keeping most of the load on main gear keeps the cost down. Dont know why cozy's, MK IV, etc. don't spread the main gear more. The main RG on my SQ2000 is 11' apart with little chance of throwing debris on the 66" prop. ---------------------------------------------------- Paul Lee, SQ2000 canard project: www.abri.com/sq2000 Russell Kent wrote in message ... ............................
