Title: Alan Tweedie: Innovator in Aircraft Nacelle Design

Introduction

Alan Tweedie is a notable inventor based in Dromore, GB. He has made significant contributions to the field of aircraft design, particularly in the development of nacelles. With a total of 2 patents to his name, Tweedie's work focuses on enhancing the functionality and maintenance accessibility of aircraft engines.

Latest Patents

One of Tweedie's latest patents is for a nacelle with a thrust reverser. This innovative nacelle design includes a translating cowl and a blocking panel. The blocking panel is connected by a pivot connection and is linked to the translating cowl through a sliding connection. This connection features an engagement member that slides within a specially designed track. The track has a first portion that runs parallel to the longitudinal axis of the outer casing and a second portion that is non-parallel. The design allows for the motion of the translating cowl to slide the engagement member without moving the blocking panel when it is within the first portion of the track. When the engagement member moves into the second portion, the motion of the translating cowl causes the blocking panel to pivot about the pivot connection.

Another significant patent by Tweedie is for a nacelle with hinged cowl doors that enable access to the engine. This design features outer and inner cowl doors that can rotate independently about offset hinge lines. A connection device is included to selectively connect the outer and inner cowl doors, allowing them to open simultaneously. The inner cowl door is designed to rotate at a greater angle than the outer cowl door, which improves access to the engine for maintenance purposes.
