Inventor: CUNHA FRANK J
IPC: F01D9/02
Filed: 2002-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an airfoil having an improved cooling mechanism. SOLUTION: An airfoil part of a turbine includes internal cavities 52, 54 and a plurality of indentations 90 disposed on inside surfaces 38 of the internal cavities. By the dents 90, heat transfer is improved to cool the internal cavities 52, 54 of the airfoil to elongate the service life of the airfoil, and the amount of compressor bleed air required is reduced to optimize engine efficiency. The advantage of such a cooling mechanism is that it does not restrict a cooling flow in the internal cavities 52, 54. The indentations 90 may have variable patterns or different geometric shapes.

Abstract: <P>PROBLEM TO BE SOLVED: To provide an interaction evaluation method of a shake table and a test piece, which can evaluate easily and surely by a simple method dynamic interaction, for which grasping in advance has been difficult until now.  <P>SOLUTION: In a method for evaluating dynamic interaction of a shake table, equipped with a vibration means and the test piece installed on the shake table, the vibration means is substituted by complex springs having frequency dependence K'<SB>Z</SB>(iω), K'<SB>X</SB>(iω), K'<SB>θY</SB>(iω), thereby modeling the shaking table. An analysis model of the test body is connected with the shaking table through rigidity and/or attenuation factor of the test body, thereby forming a coupled model of the shake table and the test piece. A virtual exciting force signal F(iω), proportional to a shaking object signal R(iω), is assumed, and a dynamic balancing relational expression for the exciting force signal and the coupled model is obtained. Based on the dynamic balancing relational expression, the dynamic specific interaction of the shake table and the test piece is evaluated.  <P>COPYRIGHT: (C)2004,JPO
