The present invention includes a thrust control apparatus, method and kit for a tiltrotor craft comprising a thrust control handle; a first and a second bar connected to the thrust control handle and connected to a floor support; a first end of a transverse bar connected to the first bar; a linker connected to a second end of the transverse bar; and a crankbell connected to the floor support below the first and a second bars, wherein a first end of the crankbell is connected to the linker, wherein the thrust control handle has a substantially linear motion that controls engine thrust, and the crankbell transfers the substantially linear motion of the handle into a substantially perpendicular motion that engages an engine thrust control at a second end of the crankbell.

Tiltrotor control

A rotor system is provided in one example embodiment and may include a rotor duct; at least one rotor blade, wherein the at least one rotor blade comprises a tip end; and a tip extension affixed at the tip end of the at least one rotor blade, wherein the tip extension is comprised, at least in part, of a flexible material and the rotor blade has a fixed extended length based on the tip extension. The tip extension may provide a clearance distance between the tip extension and the rotor duct.

Ducted rotor blade tip extension

A rotor system is provided in one example embodiment and may include a rotor duct; at least one rotor blade, wherein the at least one rotor blade comprises a tip end; and a tip extension affixed at the tip end of the at least one rotor blade, wherein the tip extension comprises a plurality of flexible elements and the rotor blade has a fixed extended length based on the tip extension. The tip extension may provide a clearance distance between the tip extension and the rotor duct.
