RISP - Rotor Ice Shed Protection
The problem: Shed ice from rotor blades can be a ballistic concern in several applications
Geared jet engines: internal and cowling damage
Tilt rotor aircraft: damage fuselage
Helicopter tail rotor: damage fenestron
Multi engine aircraft: damage fuselage
Wind turbines: danger to humans and animals
RISP rotor shed ice protection system
A protection system to prevent hazardous ballistic impact from rotor shed ice named RISP (Patent: A50377/2017) has been developed by Markus Villinger and Jose Palacios. RISP is capable to prevent from large pieces of ice sliding off the tip of the blade after delamination.
RISP systems may be designed for a wide variety of Rotors - often even as a retrofit system and may be used in combination with other ice protection systems.
