    Abstract: A system is provided for matching a new hole on an overlying member (24) with an existing hole in an underlying member (20). With a magnet placed in the existing hole, an indicator device (30) having an internal cavity, an outer boundry and a ferrous ball freely movable within the internal cavity is slid across the surface of the overlying member and in engagement therewith. When the ferrous ball overlies the magnet, a position on the overlying member aligned with the existing hole in the underlying member is thereby located. Thereafter, the indicator device (30) is removed from the overlying member and replaced by a drill guide (56). The drill guide (56) is used to locate a drill to cut a hole through the overlying member coincident with the existing hole in the underlying member.

    Abstract: A gas jet (54) is positioned above the water nozzle (28) of a system (24) provided for ultrasonically detecting flaws in an article (22) to be inspected. The water nozzle (28) directs a substantially level water jet stream (30) against an upright surface (34) of the article (22). A transducer (32) transmits ultrasonic energy along the water jet stream (30) and receives echoes from flaws existing in the article (22). The gas jet (54) directs a gas jet stream (30A) which is substantially parallel to, and vertically aligned with, the water jet stream (30). The gas jet stream (30A) serves to deflect the water splashing off the surface (34) and prevents the splashing water from descending toward and striking the water jet stream (30). In a further embodiment, opposed systems (24, 50) may be positioned to direct water jet streams (30, 52) and gas jet streams (30A, 52A) against the article (22) from opposite sides of the article with the opposed water jet (30, 52) and gas jet streams (30A, 52A) being substantially parallel and vertically aligned.

    Abstract: A stripline or microstrip feed system (10) distributes electromagnetic power among a set of utilization devices such as radiators (22) of an array antenna. In the feed system, elongated assemblies of microwave couplers (38) are arranged side by side to provide for a two-dimensional array of couplers corresponding to a two-dimensional array of radiators in rows and columns of an array antenna, and providing beam steering perpendicular to the rows. Each coupler assembly comprises different forms of couplers for providing both an amplitude and phase taper for the radiation radiating from each row of radiators. The couplers include a Wilkenson coupler (44), a hybrid coupler (46), and a backward wave coupler (48) which serve as power dividers during transmission. The couplers (44, 46, 48) are connected in series, and wherein a particular coupler has a first output terminal (e.g. T2) coupled to an input terminal (T1) of a next coupler while a second output terminal (e.g. T3) of the particular coupler is connected to a radiator of the antenna array. Each coupler assembly has a main conductor (60) which interconnects the couplers to provide a configuration having a narrow width which is less than approximately one free-space wavelength.

    Abstract: A system for drilling through contiguous first and second plate members (24, 26) such that the formation of burrs at their interface is avoided. A pilot hole (136) is drilled through the first plate member (24) and the plate members are then placed in a jig (28). A horseshoe shaped yoke (22) loosely suspended from a movable frame (38) straddles the plate members with first and second legs (32, 34). A hole finding pin (138) on the first leg (32) is manually inserted into the pilot hole (136). Thereafter, opposed clamps (52, 54) on the legs engage the plate members in the region of the pilot bore (136). From the side of the second plate member (26), bores are drilled through the plate members using a drill (152) which is mounted on the second leg (34) of the yoke (22). Perpendicularity sensors (162) on the second leg (34) engage the second plate member (26) to determine its orientation and the yoke (22) is movable for adjustment based on the signals from the sensors (162).

    Abstract: A strain transducer (14) is responsive to a deflection thereof for providing a detectable output signal having a characteristic that is expressive of the deflection. The transducer includes an optical fiber having an input port (16) for coupling to a source (18) of optical radiation and an output port (20) for coupling to a receiver (22) of the optical radiation. The optical fiber has at least one region (14') that has a radius of curvature that is equal to or less than a critical radius of curvature for the optical fiber. The at least one region includes a detectable loss in the optical signal in response to being deflected. The optical fiber is disposed within a plane and the detectable loss is shown to be greater for an out-of-plane deflection than for an in-plane deflection. The strain transducer is shown to be especially useful for inclusion within a laminated composite structure, such as a component of an aircraft wing.

    Abstract: A method of repairing damages in a superalloy component is disclosed wherein existing brazed joints and protective coatings are not harmed. The method entails the use of a silicon-free metal mixture comprising (i) a low melting alloy having a liquidus below the temperature to be used to deposit the metal mixture, (ii) an alloy melting above about 2100 DEG F, and (iii) optionally nickel. The resultant repair has a solidus temperature of at least 1950 DEG F, preferably at least 2000 DEG F.
