Abstract:
Die Erfindung bezieht sich auf eine Strömungsmaschine umfassend ein den Strömungskanal der Strömungsmaschine radial begrenzendes Innengehäuse, wobei um das Innengehäuse eine Wärmedämmschicht angeordnet ist, und wobei die Wärmedämmschicht des Innengehäuses eine Beschichtung aus mikroporösem Kunststoff ist, der Hohlkugeln unterschiedlichen Materials und verschiedener Größe beigefügt sein können, sowie auf ein Verfahren zur Beschichtung der Strömungsmaschine und die Verwendung eines mikroporösen Kunststoffs zur Beschichtung einer Strömungsmaschine.
Abstract:
An airfoil is disclosed. The airfoil may comprise a leading edge, a body portion and a trailing edge formed from a high-modulus plating. The body portion of the airfoil may be formed from a material having a lower elastic modulus than the high-modulus plating. The high-modulus plating may improve the stiffness of the trailing edge, allowing for thinner trailing edges with improved fatigue life to be formed.
Abstract:
A vane assembly within a mid-turbine frame of a gas turbine engine includes an airfoil that extends between an outer platform and an inner platform. The airfoil includes an outer wall defining a leading edge of a first radius. An inner wall of the airfoil defines an inner cavity including a forward portion proximate the leading edge defining a second radius different than the first radius.
Abstract:
The invention relates to a method of manufacturing a pi-section reinforcing piece (10) made of composite material, the method involving using three-dimensional weaving to create a first set of layers of threads which layers are joined together to form a first fibrous rough form part (102) intended to form a base preform, using three-dimensional weaving to create a second set of layers of threads which layers are joined together to form a second fibrous rough form part (104) intended to form a stiffener preform, threads of the second set being connected by weaving to the threads of the first set along a central disconnection strip (106) that widens towards the lateral edges (102a) of the first fibrous rough form part in a region (108, 110) corresponding to the step of the base, shaping the two fibrous rough form parts to obtain a fibrous preform (100) in a single piece that has a part forming the base preform and a part forming a stiffener preform, and applying a resin to the fibrous preform using a die. The invention also relates to a pi-section reinforcing piece obtained using the method.
Abstract:
A method for fabricating a micromachine component of resin comprising step (a) of forming a sacrifice layer on a substrate, step (b) of forming at least two photosensitive resin composition layers sequentially on the sacrifice layer, and performing photolithography of each photosensitive resin composition layer to form an air gap portion defining the circumferential edge portion of the micromachine component and an air gap portion where an internal structure of the micromachine component is constituted to form a multilayer structure, step (c) for depositing dry film resist on the multilayer structure of the cured photosensitive resin composition layer, and performing photolithography of the dry film resist layer to form a cured dry film resist layer in which an air gap portion defining the circumferential edge of a shroud layer and an air gap where the structure of the shroud layer is constituted are formed, and step (d) for separating the micromachine component having the multilayer structure of the cured photosensitive resin composition layer and the cured dry film resist layer from the substrate by removing the sacrifice layer.
