Hence, a critical element of the project presented here will be to minimise the weight of the system well below existing commercially available machines, exploiting the very low duty cycle required from the application whilst maintaining the levels of safety and reliability needed from this type of aircraft system. For this to be viable, a thorough understanding of the electrical and thermal behavioural of the electric braking system must be formulated, resulting in the lowest mass system possible. </p><p>The programme is funded as part of the 1.6Bn Clean Skies Joint Technology Initiative (JTI). </p> <br /> </div> <!-- End of LHS --> <div id="RHS"> <h1 id="RHSTitle">&nbsp;</h1> <p>&nbsp;</p> </div> <!-- End of RHS --> </div> <!-- End of Main Columns --> <div id="PageBottom"> <div class="PageBottomLine"> </div> <div id="CopyrightBottom"> HERRB Partners, 2011 </div> <div id="Legal"> <a href="HERRB website legal.html">Legal Information</a> </div> <div id="PageBottomEnd"></div> </div> <!-- End of PageBottom --> <div class="Spacer" style="height: 15px;"></div> </div> <!-- End of MainPage --> </div> </body> </html>
