    摘要: An open-ended housing is adapted to be communicatively connected to a conduit for receiving fluid flowing therethrough, and has a plate means defining an orifice within the housing for restricting the flow of fluid therethrough, with novel sensing means so arranged on opposite sides of the orifice as to sense relatively high static pressure at a plurality of points upstream of the orifice and to sense sub-atmospheric static pressure at a plurality of points downstream of the orifice, and a pressure responsive means is operatively connected to the sensing means for determining the differential pressure on opposite sides of the orifice.

    摘要: A method and apparatus are disclosed for brazing articles such as honeycomb sandwich structures. The apparatus includes a cold wall box-like housing separable into upper and lower sections. Each section carries a ceramic die member provided with passageways terminating in small ports for conducting a cooling fluid adjacent to the work. The workpiece is heated by electrical resistance heater strips passing above and below the workpiece. Means are provided for evacuating the housing and back-filling it with argon. When the workpiece is brought to brazing temperature, two expandable bags are inflated. One bag raises the lower die section to form a general fit with the upper one. The second bag is in direct contact with the upper face of the workpiece and exerts a uniform pressure normal to its surface. After brazing, the bags are deflated and chilled argon is introduced through the die passages to cool the work. Other features include localized temperature control by electron emission or cooling tubes and vapor removal by means of a cold trap.

    摘要: Apparatus and method, in preferred form, particularly adapted for evenly depositing a brazing powder at the interface of a honeycomb sheet and a substrate. The apparatus is comprised of a head having a working face defined by a porous medium, the medium permitting suction therethrough but preventing powder from passing therethrough. The face of the head is provided with shims of a preselected thickness, that thickness being dependent on the weight of powder per unit area to be deposited. In use, a partial vacuum is established on one side of the head''s working face and the powder to be deposited is placed on the other side of the face, the powder thereby being held to the face. A definite and reproducible powder thickness is established by scraping excess powder off the face through use of a knife edge in cooperation with the shims. The honeycomb sheet is preliminarily fixed to the substrate such as, for example, by tack-welding. Thereafter, the powder-coated face of the head is positioned over the honeycomb sheet and the vacuum released. This allows the powder to drop from the head''s working face through the honeycomb cells onto the substrate surface. Such results in an even distribution of powder on the exposed area of the substrate, and is a practical method of achieving such distribution in that no skilled operator is required.

    摘要: Inaccurate readings of the air flow in an air flow system obtained by an air flow sensor because of an uneven air velocity distribution at the sensor are reduced in accordance with the present invention by providing an air redirecting means in the air flow closely adjacent and upstream from the air flow sensor. The air redirecting means is mounted for movement in response to impingement thereon of an air flow having an uneven velocity distribution so as to redirect the air flow and provide a more representative air velocity condition at the sensor.

    摘要: A THRUST REVERSER FOR A FAN JET ENGINE OF THE TYPE HAVING A MAIN DISCHARGE DUCT SURROUNDED BY A FAN DUCT TERMINATING IN SUBSTANTIALLY THE SAME PLANE. THE TRUST REVERSER INCLUDES A MOVABLE COWL DISPOSED AROUND THE OUTER DUCT WALL OF THE FAN DUCT DURING NORMAL OPERATION OF THE ENGINE. THE MOVABLE COWL IS PROVIDED WITH TWO SETS OF FORWARDLY ANGULATED CASCADES WHICH ARE NORMALLY COVERED BY MOUNTED COVER DOORS. THE MOVABLE COWL ALSO CARRIERS TWO ARCUATE BLOCKER DOORS NORMALLY DISPOSED IN A STOWED POSITION ADJACENT TO THE INSIDE WALL OF THE MOVABLE COWL. THE MOVABLE COWL IS CARRIED BY A PAIR OF TRANSLATABLE RAILS. THE RAILS ARE EFFECTIVE TO SHIFT THE COWL TO A POSITION AFT OF THE EXHAUST ENDS OF THE MAIN JET AND FAN JET DUCTS. THE RAILS ARE DRIVEN BY A RACK WHICH IS RELEASABLY LATCHED TO THE RAILS. AFTER THE RAILS HAVE SHIFTED THE COWL TO ITS REARMOST POSITION, THE RACK IS DISENGAGED FROM THE RAILS, AND IS MOVED REARWARDLY ALONG THE RAILS. THE RACK IS LINKED TO THE MOVABLE BLOCKER DOORS AND DURING ITS FINAL MOVEMENT IS EFFECTIVE TO SHIFT THESE BLOCKER DOORS INWARDLY TO BLOCK OFF INTERIOR PASSAGE THROUGH THE MOVABLE COWL. WITH THE DOORS IN THEIR DEPLOYED POSITION, BOTH THE MAIN JET STREAM AND FAN JET STREAM IMPINGE UPON THE DOORS AND ARE REDIRECTED TO BE DISCHARGED THROUGH THE CASCADES, WHEREBY THEY ARE REVERSED IN DIRECTION.

    摘要: A lightweight, easily manufactured and assembled thrust reversing cascade assembly for jet engines. The assembly includes a plurality of turning vanes positioned in spaced relation and locatable aft of a jet engine exhaust. Each turning vane is rigidly supported in fixed spacial relation to other such turning vanes by a support assembly which includes a plurality of planar spacer members. Each spacer member includes a tab portion which extends from the spacer body a distance sufficient to pass through a slot in a turning vane. Each spacer also includes a notch on the end opposite the tab to receive the tab projecting through a turning vane from another spacer member. A pair of straps are positioned on both sides of the planar spacer members and also extend through the slots in each turning vane. Tensioning means is provided at opposite ends of the straps to place the straps in tension while providing compression forces on the spacers and turning vanes to rigidly support the turning vanes in spaced relation.
