摘要： The divergent seal of a thrust vectoring nozzle has an elongated corrugated stiffening sheet with a backbone secured to the air side. The backbone is stiff perpendicular to the sheet, but flexible in torsion. A face sheet secured only at the upstream end covers the gas side of the stiffening sheet.

摘要： A trailing edge flap moveable from a stowed position behind a wing to a downwardly and rearwardly extending position to deflect jet exhaust from an upper surface blowing jet engine downwardly and rearwardly to augment lift. The actuating mechanism rotates the flap about a variable radius which maintains the upper surface of the flap in contact with and generally in tangential alignment with the trailing edge of the upper surface of the wing. This mechanism comprises forward and rear radius links pivotally mounted at their lower ends to a stationary mounting arm, and extending upwardly and divergently therefrom to attach to the flap. In two embodiments, the rear radius link has its pivot end mounted to a moveable member which in turn enables the flap to be rotated so that its forward end moves downwardly. Thus, in its fully deployed position, the flap can be rotated to form a slot between the aft end of the wing and the leading edge of the flap.

摘要： A gas turbine engine cowl has a portion which translates axially of the remainder, to open or close a reverser gas flow gap. A yoke is attached to the fixed cowl upstream of the gap which yoke is engageable with a member on the translating cowl portion, by dropping thereover as the cowl portion closes the gap. Translation of the cowl portion actuates an abutment via a cam mechanism to release the yoke at such a time as to prevent the yoke dropping too soon, which would result in the cowl portion being unlocked.

摘要： A flow deflector blade 4 primarily for mounting within the efflux of an aircraft propulsion fan so that a change of flow direction can be effected, includes a leading edge member 6, a trailing edge member 7, a leaf spring member 8 of arcuate form connecting the two, and filler portions 12, 13 of rubber bonded to each side of the leaf spring member shaped to provide a desired blade contour.

摘要： A by-pass gas turbine engine capable of producing an unmixed exhaust stream which comprises a core of hot turbine exhaust gases surrounded by an annular layer of by-pass air, is combined with a target thrust reverser. The ratio of the total pressure of the by-pass air to the total pressure of the turbine exhaust gases is arranged to be greater than unity to a significant extent, and the buckets are made from lightweight materials such as titanium, light alloys or even fiber re-inforced composite materials.
