  • Patent number: 9731351
    Abstract: A part (P) includes a first (FP), and a second portion (SP), which meet at an interface (IF). A channel (CH) extends from the first portion (FP) through the interface (IF) into the second portion (SP). Further there is a method to generate the part (P). To refurbish a part with tiny geometry channels, the second portion (SP) is produced by additive manufacturing technology on the interface (IF) with the first portion (FP), the channel (CH) has a first average diameter (DI) in the first portion (FP) and the interface (IF), and the channel (CH) has a second average diameter (D2) in the second portion (SP) at said interface (IF). The second diameter (D2) is larger than the first diameter (DI). The channel (CH) has a first tapered portion (TP) which narrows in the second portion (SP) at increasing distance from the interface (IF).

  • Patent number: 9541005
    Abstract: There is described a system and method for filling an engine fuel manifold. An adaptive filling function is used to determine a flow rate at which fuel is to be delivered to the fuel manifold. The filling function receives as an input a present measurement of the engine's speed and computes the flow rate accordingly. The fuel manifold may then be filled according to the computed flow rate so as to match the engine's speed. Appropriate fuel/air ration conditions can therefore be achieved for successful engine start.
