BALL
Following my EFAT O topic recently, I would think that the plane would have a load of fuel just after takeoff, meaning that should a landing be on land with rough grooves, the chances of flipping over would be high, with resultant fire risks.
It got me thinking...how can we prevent the plane flipping over (I am talking about normal tricycle with front steering)? The thing to cause the flipover would be, I guess, grooves that the front wheel cannot climb.
Is there any merit in having the front wheel as a ball, you know, along the lines of a barrow-ball or a Dyson Ball vacuum cleaner? I am not an engineer and haven't got the foggiest how such a thing would be made, but I think a ball type wheel would just roll over most ridges, especially if it was out- sized (thing penny farthing in reverse, although not so big).
To reduce drag, maybe have pimples, like golf balls do?
Anyway, over to the folks with the brains....
