Abstract
Abstract A reel launcher having a saddle operationally deployable beneath an aircr for carrying and towing an aerial tow target. The tow target is connected to the tow cable by an adapter which includes a notch for registration with a latch in the launcher. The adapter includes a nose section and one of a plurality of end fittings specially formed to engage a corresponding connection in different tow targets. The length of the adapter is adjustable by a threaded connection between the nose section and the end fitting which may be locked with the notch in proper alignment by a slot, key and notch arrangement between the two ends. Thus, a single nose section operable with a launcher may be used with different end fittings and tow targets with no other modifications.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
214 words
A universal tow target adapter for precise alignment with a latch mechanism of a reel laucher, comprising: a cylindrical nose section having a coaxial aperture extending into the forward end for receiving the trailing end of a tow cable from the launcher and terminating in an annular seat for resisting forward movement of a flange means at the trailing end of the cable, said nose section being tapered at the forward end and having a first external notch on one side only for engaging the latch mechanism of the launcher, said nose section further having a second notch at the rearward end aligned with said first notch; an end fitting threadingly coupled at one end to the rearward portion of said nose section for adjusting the overall length of said adapter, and formed at the other fitting end to be connected to a tow target, said fitting having a slot along the threaded portion positioned to ensure a precise rotational alignment of said first and second notches with said end fitting; a key slidingly received in said second notch and said slot for locking and preventing relative coaxial rotation of said section and said fitting; and locking means coupled to said end fitting for securing said key in said second notch and said slot.
Claim 2
Dependent Claim
214 words
A universal tow target adapter for precise alignment with a latch mechanism of a reel laucher, comprising: a cylindrical nose section having a coaxial aperture extending into the forward end for receiving the trailing end of a tow cable from the launcher and terminating in an annular seat for resisting forward movement of a flange means at the trailing end of the cable, said nose section being tapered at the forward end and having a first external notch on one side only for engaging the latch mechanism of the launcher, said nose section further having a second notch at the rearward end aligned with said first notch; an end fitting threadingly coupled at one end to the rearward portion of said nose section for adjusting the overall length of said adapter, and formed at the other fitting end to be connected to a tow target, said fitting having a slot along the threaded portion positioned to ensure a precise rotational alignment of said first and second notches with said end fitting; a key slidingly received in said second notch and said slot for locking and preventing relative coaxial rotation of said section and said fitting; and locking means coupled to said end fitting for securing said key in said second notch and said slot.
Claim 3
Dependent Claim
39 words
A universal adapter according to claim 1 where said nose section includes an element formed to be secured to the end of the cable, and thrust bearing means operatively connected between said element and the wall of said cavity.
Claim 4
Dependent Claim
28 words
A universal adapter according to claim 2 wherein said key includes a first portion slidingly received in said slot and a second portion received in said second notch.
Claim 5
Dependent Claim
50 words
A universal adapter according to claim 3 wherein said locking means comprises: a collar threadingly engaged to said end fitting for retaining said key in said second notch and said slot; and an elastomeric element bonded to the threads of said end fitting and frictionally restraining said collar from rotation.
Claim 6
Dependent Claim
20 words
An improved universal adapter according to claim 2 wherein said end fitting includes a hole for passing said element therethrough.
Claim 7
Dependent Claim
200 words
In an aerial tow target system having a tow cable deployable from a reel launcher carried by a tractor aircraft, said cable having a flange means at the trailing end, an improved adapter connected between the trailing end of the cable and a target, and a latch mechanism in the launcher for engaging the adapter to secure the target in the launcher when fully retrieved, wherein the improved adapter comprises: a cylindrical nose section having a coaxial aperture extending into the forward end for receiving the trailing end of the cable and terminating in an annular seat for resisting forward movement of said flange means, an external notch on one side thereof, and an internally threaded rearward portion; and an end fitting threadingly coupled to the rearward portion of said nose section and formed to be directly connected to the target for adjusting the longitudinal and rotational position of said fitting relative to the notch to ensure precise alignment with the latch mechanism at the point of full retrieval of the adapter and target; and locking means operatively connected to said nose section and to said end fitting for maintaining the position of said notch relative to the end fitting.
Claim 8
Dependent Claim
200 words
In an aerial tow target system having a tow cable deployable from a reel launcher carried by a tractor aircraft, said cable having a flange means at the trailing end, an improved adapter connected between the trailing end of the cable and a target, and a latch mechanism in the launcher for engaging the adapter to secure the target in the launcher when fully retrieved, wherein the improved adapter comprises: a cylindrical nose section having a coaxial aperture extending into the forward end for receiving the trailing end of the cable and terminating in an annular seat for resisting forward movement of said flange means, an external notch on one side thereof, and an internally threaded rearward portion; and an end fitting threadingly coupled to the rearward portion of said nose section and formed to be directly connected to the target for adjusting the longitudinal and rotational position of said fitting relative to the notch to ensure precise alignment with the latch mechanism at the point of full retrieval of the adapter and target; and locking means operatively connected to said nose section and to said end fitting for maintaining the position of said notch relative to the end fitting.
Claim 9
Dependent Claim
90 words
An improved adapter according to claim 6 wherein said locking means further comprises: a longitudinal groove formed in the threaded portion of said end fitting; a recess in the rearward end of said nose section alignable with said groove at predetermined intervals of adjustment; a key slidable in said groove and said recess when aligned for preventing relative rotation of said nose section and said end fitting; and collar means threadingly coupled to the threaded portion of said end fitting for securing said key in said groove and said recess.
Claim 10
Dependent Claim
42 words
