PROGRAM DESCRIPTION

 R1 SCR mass Ms =1.66 10-10ve3 a m R2 winding mass Mw =0.122vem for MDRE =0.142vem for MDLL

equal to associated power and radiator mass
 R3 feeder mass MF =7.19 10-4veam for MDRE =7.97 10-4veam for MDLL

equal to associated power, radiator and capacitor mass
 R4 kinetic power massMkin =0.0025 m1ve2 for MDRE =0.0007 m1ve2 for MDLL
 R5 total electric mass Melec =Ms + 2Mw + 3MF + Mkin
 R6 total mass Mtot = 1.5Melec
 R7 total lengthStot =0.847ve2 /a
 R8 waste powerPw = [R2 + R3] 1/0.025 for MDRE; Pw = [R2 + R3] 1/0.034 for MDLL
 R9 total power Ptot = [R8] + [R4] 1/0.005 for MDRE; Ptot = [R*] + [R4]1/0.014 for MDLL
 R0 efficiency Eff = [R9 - R8]/[R9]
