Embodiment Construction

[0010] Disclosed herein are aircraft nacelle assemblies and associated methods, wherein the aircraft nacelle assemblies are configured to facilitate manual opening and closing of a cowling of the nacelle. More specifically, a nacelle assembly according to the present invention may be described as having a manually assisted mechanism that facilitates manual opening and closing of the nacelle cowling, even when the nacelle cowling is heavy, such as at 40-250 pounds (lb) (approximately 175-1,100 This is still the case when within the range of cattle (N)). Accordingly, an aircraft nacelle assembly according to the present invention may facilitate engine maintenance because the cowl is easier to operate with a manual assist mechanism included than without (eg, using only brute force to overcome the weight of the cowl).

[0011] exist figure 1 In , an exemplary aircraft 90 is shown; however, other types and configurations of aircraft are also included within the scope of the presen...

Abstract

Aircraft nacelles include a frame (12), a cowl (14) operatively and rotatably coupled to the frame, and a biasing member (20) operatively coupled between the frame and the cowl. The biasing member is configured to assist in the manual opening of the cowl and the manually closing of the cowl.

Description

technical field [0001] The invention relates to aircraft cabins. Background technique [0002] Larger aircraft typically include turbofan engines enclosed by nacelles. The nacelle includes a number of rotatable cowls that provide access to the turbofan engine for maintenance. Handling large and heavy spinners can be difficult for maintenance personnel. Currently, large and heavy engine cowlings are operated with the aid of electrically or hydraulically driven actuators. Electric powered actuators are powered by onboard or ground power. Hydraulically driven actuators are driven by electric pumps or manually operated pumps such as hand pumps. These types of systems are a cause of additional complexity, cost and maintenance for aircraft manufacturers and airlines. Therefore, a fully manual system is required to allow maintenance personnel to operate and open the large and heavy cowls. Contents of the invention [0003] An aircraft nacelle assembly includes a frame, a co...
