BLADE AND ROTOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18476683 titled 'BLADE AND ROTOR

Simplified Explanation

The abstract describes a blade for use in a rotor of an aircraft that is swept in a region extending to a blade tip from a first position located between the rotation center of the rotor and the blade tip in a radial direction of the VTOL rotor. The sweep amount increases from the first position toward the blade tip, and the rate of change of the sweep amount in a region extending to the blade tip from a second position located between the first position and the blade tip in the radial direction of the VTOL rotor is greater than the rate of change of the sweep amount in a region extending from the first position to the second position.

  • The blade is designed to have a swept shape that increases towards the blade tip.
  • The rate of change of the sweep amount is higher closer to the blade tip.
  • The design is optimized for use in VTOL rotors for improved performance.
      1. Potential Applications

        1. Unanswered Questions
        1. How does the swept shape of the blade impact the aerodynamics of the rotor system?

The swept shape of the blade can affect airflow and lift generation, but the specific aerodynamic implications are not discussed in the abstract.

        1. What materials are used in the construction of the swept blade for VTOL rotors?

The abstract does not mention the materials used in the construction of the swept blade, which could be crucial for durability and performance.


Original Abstract Submitted

A blade for use in a rotor of an aircraft is swept in a region extending to a blade tip from a first position located between the rotation center of the rotor and the blade tip in a radial direction of the VTOL rotor, the sweep amount increases from the first position toward the blade tip, and the rate of change of the sweep amount in a region extending to the blade tip from a second position located between the first position and the blade tip in the radial direction of the VTOL rotor, is greater than the rate of change of the sweep amount in a region extending from the first position to the second position.
