"We are very intrigued by SpinLaunch's innovative use of rotational kinetic energy to revolutionise the smallsat market," Wen Hsieh, a general partner at Kleiner Perkins, said in an emailed statement.
The kinetic energy mainly includes the rotational kinetic energy of the motor rotor and the rotational kinetic energy of the joint [A.sub.i], the translational kinetic energy of driving rod, the concentrated translational kinetic energy of the joint [B.sub.i] and its own rotational kinetic energy, and the translational kinetic energy of the intermediate link, where the rotational kinetic energy of joints [A.sub.i] and [B.sub.i] is mainly produced by its internal bearing.
Biasing the mass toward the center of the NSX reduces the polar moment, making the car respond (yaw rate) faster to steering inputs and reducing its rotational kinetic energy. In other words, it's easier to initiate a turn, and easier to stop the rotation.
Besides, the translational kinetic energy of each part is [K.sup.v.sub.Gi0] = 1/2 [m.sub.Gi] [[v.sub.i0]].sup.T] [[v.sub.i0]]; the rotational kinetic energy of each part is [K.sup.[omega].sub.Gii] = 1/2 [I.sup.ii] [[[[omega].sub.i0x.sup.2] [[omega].sub.i0y.sup.2] [[omega].sub.i0z.sup.2]].sup.T].
The rotor blades transform the linear kinetic wind energy into rotational kinetic energy in a first step and finally the rotational kinetic energy is converted into electrical energy with the help of generator.
The first three terms represent the translational kinetic energy and the last one describes the rotational kinetic energy about the x-axis.
