Patent number: 11236616Abstract: A turbomachine airfoil element includes an airfoil that has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 4.47-4.77 inch (113.5-121.2 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span and is in a range of 2.57-2.87 inch (65.3-72.9 mm). The airfoil element includes at least two of a first mode with a frequency of 297±10% Hz, a second mode with a frequency of 1035±10% Hz, a third mode with a frequency of 1488±10% Hz, a fourth mode with a frequency of 1524±10% Hz, a fifth mode with a frequency of 2855±10% Hz and a sixth mode with a frequency of 4462±10% Hz.Type: GrantFiled: January 11, 2018Date of Patent: February 1, 2022Assignee: Raytheon Technologies CorporationInventors: Kurt R. Heinemann, Sumin Tao, Christopher B. Jelks, Xuedong Zhou, Mark David Ring, Konstantinos Panagiotis Giannakopoulos, Kate Hudon, John Joseph Papalia

Publication number: 20050104239Abstract: A method and mold assembly to control the polymerization of a molded article. In one embodiment, an amorphous posterior mold comprising a non-critical surface having a controlled radius of curvature is used to produce molded articles. In an alternate embodiment, ophthalmic lenses are produced using a posterior mold in which the concave surface of the non-critical surface is filled with a liquid having a similar refractive index as the mold material. In still another embodiment, a positive lens is placed at a predetermined distance adjacent to the mold assembly to alter the irradiation path to the mold assembly. In still another embodiment, a positive lens is placed within the concave surface of the posterior lens.Type: ApplicationFiled: October 20, 2004Publication date: May 19, 2005Inventors: Griffith Altmann, Lisa Armstrong, Kevin Beebe, Ian Cox, Horngyih Huang, Michael Lesczynski, Arthur Martin, Michelle Moran, Joseph Papalia, Dominic Ruscio
