Planetary Exploration Using Biomimetics<br />

An Entomopter <strong>for</strong> Flight on Mars<br />

curves shown in Figure 3-2 show the <strong>for</strong>ce and mass distributions <strong>for</strong> a generic case. The curve<br />

profiles should be the same <strong>for</strong> all operating conditions and wing sizes; only the absolute values<br />

should be affected by a change in these parameters. From this figure it can be seen that the maximum<br />

<strong>for</strong>ce occurs about midway along the wing section. Further toward the wing tip, the <strong>for</strong>ce<br />

is reduced. Although wing acceleration increases towards the tip the mass is decreasing and produces<br />

a net reduction in <strong>for</strong>ce. The opposite occurs toward the root, where there is greater mass<br />

but less acceleration, thereby reducing the total <strong>for</strong>ce.<br />
