This paper introduces four unique, low energy, mechanical de-ice systems whose performance meets the requirements for rotor blades and inlets. The four systems are: 1) Small Tube Pneumatic De-Icer (STP), 2) Pneumatic Impulse Ice Protection (PIIP), 3) Electro-Expulsive De-Icing System (EEDS), and 4) Eddy Current System (EC). These systems are designed to remove ice in small particles that would damage engine components or cause fuselage damage resulting from ice particles launched from a rotor blade. The systems are also capable of shedding very thin layers of ice critical to the retention of airfoil shapes on rotor blades, wings and stabilizers. The first two systems, STP and PIIP, are pneumatically powered while the second two, EEDS and EC, are operated electrically. All four systems can use discharged, stored energy de-icing pulses that result in a low power drain from the helicopters power resources. These systems can all be designed intrinsically into the airfoil to eliminate aerodynamic effects or can be bonded onto existing airfoils in retrofit applications.
