WING ASSEMBLIES WITH THREE-POSITION KRUEGER FLAPS AND METHODS OF OPERATING THREE-POSITION KRUEGER FLAPS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240017819 titled 'WING ASSEMBLIES WITH THREE-POSITION KRUEGER FLAPS AND METHODS OF OPERATING THREE-POSITION KRUEGER FLAPS

Simplified Explanation

The patent application describes a wing assembly that includes a three-position Krueger flap and an actuation assembly. The actuation assembly consists of a drive linkage assembly, a primary linkage assembly, and a secondary linkage assembly.

  • The primary linkage assembly is connected between the drive linkage assembly and the three-position Krueger flap. It is designed to pivot and translate relative to a wing support structure.
  • The secondary linkage assembly includes a cam, a follower, and a dual-linkage axle. The dual-linkage axle is connected to both the follower and the dual linkage, and it defines a pivot axis for the dual linkage.

Potential applications of this technology:

  • Aircraft wing assemblies can benefit from improved control and maneuverability with the three-position Krueger flap and the actuation assembly.
  • The design allows for precise adjustments and positioning of the Krueger flap, enhancing the aerodynamic performance of the aircraft.

Problems solved by this technology:

  • The wing assembly provides a reliable and efficient mechanism for controlling the Krueger flap, allowing for better control of airflow and lift during different flight conditions.
  • The dual-linkage axle and the primary linkage assembly enable smooth and accurate movement of the Krueger flap, reducing the risk of malfunctions or improper positioning.

Benefits of this technology:

  • Improved aerodynamic performance and control of the aircraft, leading to enhanced maneuverability and stability.
  • Increased efficiency and fuel savings due to optimized airflow and lift characteristics.
  • Enhanced safety and reliability through the use of a robust and precise actuation assembly for the Krueger flap.


Original Abstract Submitted

wing assemblies comprise a three-position krueger flap and an actuation assembly that comprises a drive linkage assembly, a primary linkage assembly coupled between the drive linkage assembly and the three-position krueger flap, and a secondary linkage assembly. the primary linkage assembly comprises a dual linkage that is pivotally and translationally coupled relative to a wing support structure. the secondary linkage assembly comprises a cam, a follower, and a dual-linkage axle that is coupled to the follower and to the dual linkage and that defines a dual-linkage pivot axis of the dual linkage.
