In Figure 6 the polar diagram of stress is presented.

7 and 8 there are the diagrams of forces loading the bearing neck as well as the polar diagram of force loading the base bearing (Bobescu, 1997).

The polarizer was rotated in 20[degrees] steps and a

polar diagram was constructed for the 4623-4608 [cm.

The maximum amplitude, and hence the shape of the

polar diagram for the AFC element, are strongly affected by the frequency filter that is applied.

A simple way to view amplitude and phase is with a

polar diagram shown in Figure 1.

The

polar diagram confirms the strong performance; on the wind in 12 knots true, the curves show about 7.

At the other end of the scale, Rod reports 4 knots of boatspeed in about 6 knots true (the

polar diagram shows 3.

Azimuthal variations of HVNR are presented on rectangular and on

polar diagrams for five elaborated points.

6 knots true, a figure supported by the

polar diagrams.

For the representation of the

polar diagrams at constant magnetic flux density, an original program was developed to interpolate the experimental results, in order to obtain the same vector of the magnetic flux density for all the measuring directions.

When flying the optional gennaker downwind on a reach at 130 degrees, the

polar diagrams promise boat speeds of up to 12 knots in 20 knots of breeze.

The

polar diagrams show that she needs 15 knots of breeze to reach 6 knots of boatspeed at 36 degrees, but as the wind builds the Harmony's upwind performance curve increases quite steeply.
