Puffin had a mass of We can perform a rough calculation to compare the designs of Puffin and Condor. Condor had a mass of 34 kg, a wing area of 75 m2 and a pilot mass of 61 kg.

Intuitively, one would think that the best solution would be the one which is aerodynamically best, rather than the one which is most structurally sound. Normally a plane banks tilts to one side in order to turn efficiently, but these long wings close to the ground could not bank without driving the inner wing tip into the ground, and there was not enough power available from the pilot to climb in order to gain airspace for manoeuvring.

In this section we will look at two approaches taken to progettazione concettuale basi di dating human-powered aircraft.

Puffin flew well enough in a straight line but did not turn easily and was a nightmare to repair after crashing. Most of the presentations and slideshows on PowerShow.

Why was Condor so successful? This design occupied a structural, rather than aerodynamic, design space. It required an innovation to break out of this aerodynamic design space which had not achieved the desired result.

The design team that produced the Puffin airplane was led by an aerodynamicist.

Condor has twice the wing area for half the mass. What we know is: The team even mounted the propeller at the back, so that it would not create any turbulence in the airflow over the wings.

The team produced an aerodynamical solution by subordinating all design decisions to the imperative of a clean airflow over the plane, with no bits sticking out in the wind to cause undesirable drag.

MacCready returned in and landed that prize with Gossamer Albatross. The requirement for winning this prize was to fly a figure-of-eight course around two pylons half a mile apart, with a minimum height of 10 feet at start and finish, using human power alone. Let's assume that the same pilot flies both machines - the pilot will be assumed to have a mass of 61 kg in both cases.

Airplane designs like the Puffin, that concentrated on aerodynamics, achieved the distance required to win the Kremmer prize but none of them turned corners at all well. The aim of the design team was therefore to extract as much lift as possible from the wings, by having the design as aerodynamically perfect as possible.
