Turbine-electric transmission enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The exhaust is fed into the power turbine used to power an output shaft for whatever desired application. The power turbine is also connected to the electric generator, which converts mechanical energy into electrical energy. The electric generator driven by the power turbine charges the battery needed in order to drive the motor that supplies compressed air into the combustor. During cruise speed the electric motor does not have to be functioning, only the gas turbine engine is required to continue
Potential energy of protein with two chemical bonds, the two bonds tend to form a fixed angle. Any variation from this fixed equilibrium angle contributes to protein potential energy. Total potential energy based on angle is defined as over set S the triplet of atoms that are connected by two chemical bonds; E = Σk(α-α) where: k is the force constant α is the equilibrium angle α is the bond angle The middle bond of three bonds formed by four atoms maintains a certain angle which is also known as torsion is defined over set S the quartet of atoms that are connected by
