a landing gear retraction scheme similar to an<br />
XB-70 Valkarie as shown in Figure 8.3. The<br />
complexity was necessary due to overall<br />
configuration drive of low supersonic maximum<br />
cross sectional area.<br />
Due to the Sears-Haack ideal of supersonic area<br />
distribution the nose gear could be easily placed<br />
in the forward fuselage. No need for complex<br />
folding arrangements led to the selection of a<br />
standard side-by-side tire configuration. The<br />
complete retraction schemes and nose wheel<br />
configuration can be seen in Figure 8.4. The<br />
completed landing gear configuration can be<br />
seen in Figure 8.5.<br />
The braking system for both the nose gear and<br />
main gear configuration would use a standard<br />
rotor disk braking mechanism. The heat-sink<br />

will be made of carbon rather than steel because of the fact that carbon is superior to steel as it<br />
has a higher thermal conductivity and temperature limit, and the thermal expansion of carbon is<br />
lower. The only drawback to carbon brakes is the lower density of carbon compared to that of<br />
