We should be careful of veering off into a topic that's part of another thread ( three-surface aircraft in aerodynamic engineering ). The Avanti is a far more successful pusher design than the ill-fated Starship. However, the Avanti is not efficient because it is a pusher, but because it is...

Agreed! I didn't say that the pusher design of the Altania or the Aeriks-200 is the reason that these designs have good performance - rather that these are two examples of the aircraft designers trying to minimize the adverse affects of the pusher configuration. There are scads of similarly...

At Aero 2003 in Freidrichshafen and at Le Bourget, another pusher designed by Broussaud Ameur was shown. The company SC2A, whose website is http://www.slicom.fr/sc2a manufacturers this aircraft, called the Altania. This configuration gets extremely high performance out of a very small Jabiru...

Good point about the separation of trim and control surfaces. The Avanti doesn't have a bad takeoff run, but it also has gobs of power... The Avanti is a brilliant design. If I had 4.3mil I might buy one as well. To me it serves to illustrate that 3LS designs must be very carefully...

The delta shaped ventral strakes on the Avanti are most likely stall prevention devices, though they do provide some needed yaw stability. Such strakes were first used on the Lear Jet. At low angles of attack, the drooped strakes provide no lift; but at high angles of attack, they develop lift...

I'm a bit late to this thread, which seems to have stagnated... but my understanding is that anhedral is applied to the forward wing to reduce dutch roll tendencies. Anhedral can also be applied to the rear stab for the same reason, and if you notice on the Avanti both the forward wing and rear...

A useful general comparison can be found at http://www.capellakitplanes.com/capella/tvp.htm A suprising finding for almost all popular pusher aircraft is that they are 5-6dB noisier than "equivalent" tractor aircraft. This is claimed to be due to the turbulent flow into the prop...
