Filed: 1988-09-02
Abstract: PURPOSE: To provide a high horse power load and high efficiency in relatively high Mach number by providing a plurality of airfoil sections, each of which has a specified airfoil sectional shape substantially on the full length of a blade. CONSTITUTION: A blade 100 has a plurality of relatively thick, super critical sections, and each section has a parabolic leading edge 115, a small camber (warp) extended from the leading edge 115 to a 40% chord, a gradual upper surface pressure recovery region extended from the 40% chord to a trailing edge, and a concave lower surface extended from 40% chord to the trailing edge for generating a specified lifting force. The value of the thickness ratio (thickness/length) of the airfoil section is changed from 2 to 7.5. This blade has the same aerodynamic performance as in the case of NACA 16 series blade. In addition, since the leading edge radius of the leading edge 115 is larger than that of the NACA series, damage by a foreign object is minimized and, since the trailing edge is more gradual compared with the NACA 16 series, not many manufacturing problems occur.

In this case, a pulse motor 24 is driven, a light-emitting element 21 and a light-receiving element 22 on a sensor-holding member 18 are moved, e.g. from left to right, and the cloth end is scanned with the light from the light-emitting element 21. At this time, concretely, the light not striking against the cloth is reflected by a reflecting plate provided on a throat plate and the reflected light is received by the light-receiving element 22. On the other hand, the light striking against the cloth is diffusely reflected and the reflected light is not received by the light-receiving element 22. Therefore, the output level of a detected signal of which is varied according to the position of the cloth end is outputted from the light-receiving element 22. In this way, since these kinds of the cloth pressers are detected by optical scanning, the whole of constitution can be simplified.
