5 . PROGRESS SUMMARES. Figure 11 shows the delivery schedule for guidnce nd nvigtion systems to be used in the Commnd Module. NASA pproved, on 1 August 1963, MT/L's proposed chnge in the composition of Blocks nd 11, thereby mking AGE 13 the first system in Block 11. However, MT/L's flow pln (Figure 12) providing for shipment of G & N systems intended for flight directly to AMR, ws not pproved pending further evlution within MSC. NASA's decision s contined in Dtfx letter, SG (PEE:wb) dted 1 August 1963, from D. Gilbert to M. Trgeser ws s follows: "The flow pln which provides for shipment of Guidnce nd Nvigtion systems intended for flight directly to AMR cnnot be pproved t this time. This flow pln is considered to be desirble from the point of view tht less running time will be on flight system thn if it were shipped to the spcecrft mnufcturer, tested t tht point s well s tested prior to lunch t AMR. t will be necessry to secure the opinions of number of MSC divisions before this flow pln cn be pproved. For present plnning purposes it should be considered tht ll systems will be shipped to the spcecrft mnufcturer for test nd ssembly with spcecrft prior to shipment to AMR. ASP will undertke to resolve this flow pln with other elements of MSC s soon s possible. "The delivery schedule presented for the Commnd Module shows chnge in Block 1 delivery from previous chnge point t System 9 to new chnge point t System 13 coincident with delivery of the first LEM Guidnce nd Nvigtion. This chnge in Block 11 strting point is considered stisfctory with the condition tht Commnd Module systems must not be delyed becuse of the LEM System Design Relese. "The flight plns for AFRM 9 cll for this to be n unmnned bllistic flight nd guidnce nd nvigtion system will not be 1

6 provided s prt of the onbord systems. G & N System No. 5, previously llocted to AFRM 9, will now be llocted to North Americn's House Spcecrft No. 1. Since the bsic electricl nd mechnicl integrtion of the G & N with the spcecrft will be performed on House Spcecrft No. 1 insted of ARFM 9, it is impertive tht this system be delivered on time s indicted in the G & N recovery pln. No relxtion will be permitted in the delivery requirements for G & N System 5. ' M[T/L submitted proposed Apollo Guidnce Equipment Flow Pin to NASA in letter AG38263, dted 23 Msy 1963, s reflected in Fig. 12. This proposl hs not yet been pproved nor hs ny lternte been dopted. After flow pln hs been pproved, Fig. 12 will be modified to indicte the respective irfrhmes to which the vrious AGE'S will be ssigned. Figure 13 shows proposed LEM flight test schedule (flow pln) giving the lloction of LEM Guidnce nd Nvigtion Systems (LGE) to LEM vehicles. This proposl ws presented to NASA by MT/L in My 1963, nd is documented in MT/L letter AG38263 dted 23 My A meeting ws held in July to determine sttus of AGE4 hrdwre (Fig (Reference Apollo Project Memo #659, dted 24 July 1963, by P. J. Srmnin). The following prgrphs hve been bstrcted from the bove nmed memo, nd supplement the AGE4 schedule informtion contined in lst month's report. "Delivery of PSA4, nd therefore the strt of nertil Subsystems testing hs slipped bout one month, from 15 August to 15 September. t is expected tht on 15 September those trys of electronics necessry to strt Subsystems tests will be vilble. Hopefully, the remining trys will be delivered in time to prevent delying the completion of Subsystem tests. "AGE4 Systems tests, s result of the one month slip indicted bove, should strt on 15 October, rther thn 15 September (see enclosure of APM #63). ACSP hs indicted tht delivery of the preproduction GSE will slip from 15 August to 1 September. "The interim AGE4 JBox nd hrness hve slipped from 26 July to 7 September, leving bout five weeks of mrrige nd checkout time. J. Flnders' test PSA JBox will follow two weeks lter. D. Test will hve one cold plte built for PSA4 rther thn depend upon NAA 's delivery.

7 . NASA confirmed on 1 August 1963 chnge in flight plns for Airfrme 9, into which AGE 5 ws to be instlled (Fig. 15). As noted in lst month's report, lignment nd clibrtion work on the AGE5 nertil Subsystem is scheduled for the period from 15 September to 15 November On 15 September, MU5, the bredbord PSA, the consignment bredbord GSE, nd the interim AGE5 CDU's should be vilble; fter short period of mrrige nd functionl checkout, ctul lignment procedures cn be strted. As with the AGE 4 nertil Subsystem, this time schedule is considered tight, nd twoshift opertion will be employed so tht the subsystem will be vilble to strt systems testing on 15 November. The blue module PSA5 is schediil~d fnr completinr? nr? 15 Gctsber; rep?zcmer;t of the bredbord PSA t tht time is possible. delivery slippge of two to three weeks, nd subsystem down time in chnging over, my be prohibitive. Consequently, initil use of PSA5 my occur in the systems lb. However, n nticipted PSA5 System ssembly nd test of AGE5 is scheduled to begin 15 November The following hrdwre or suitble substitutes must be vilble nd redy on tht dte. ) MU5 b) PSA5 (blue module) c) Preproduction GSE d) CDU5 e) Cooler *f) AGE5 hrness nd JBox (mrried nd checked out) *g) D&C5 *h) N. B. 5 * i) AGE5 Optics Subsystem "j) AGC5 :kk) AGE fixture (including cold pltes) The sterisked equipment is required in the systems lb on 15 October for mrrige nd functionl checkout prior to systems tests. Figure 16 showing the Apollo Milestone Chrt for AGE9 will be deleted from future Technicl Progress Reports. n ccordnce with the directive in Dtfx letter SG (PEE:wb) dted 1 August 1963 from D. Gilbert to M. Trgeser, ll work on AGE9 hs cesed nd efforts re now towrd delivery of AGE13 s the first Block 1 AGE system in its sted. A schedule for Guidnce Theory nd Progrmming is shown in Figure 17. t is plnned to replce this chrt with schedule derived from the existing PERT chrt covering this effort. Figure 18 gives the delivery schedule for ll guidnce computers. AGC4, n MT/L bredbord unit, is functioning nd will be vilble for use with AGE4 8 3 n

8 when required. Tlie present outlook for AGC5 is tht it will be cverl weeks lte. t is plnned tht AGC 4l3, the Rytheon Lerner Model, will be used in its plce during system ssembly nd test of AGE 5. However, the ltest PERT forecst is tht AGC 4R will be delivered on 24 Februry 1964, pproximtely twelve weeks lter thn its scheduled dte of 1 December AGC 6, scheduled for delivery to AC Sprk Plug on 15 Jnury 1964, is expected to be delivered on 8 April 1964, pproximtely twelve weeks behind schedule. Figure 19 shows the delivery schedule for ll MU's. Therml testing is continuing on MU 1. MU 2 will be rebuilt with new stub shfts nd vibrtion tests will be rerun. MU 4 is undergoing functionl checkout nd lignment tests s prt of the AGE 4 inertil subsystem mrrige nd checkout. MU 5 intergimbl subssemblies re being wired nd resolvers rb being checked. All other prts for MU 5 re vilble except the PP'S nd cse, which should be vilble in the ner future. MU ssembly drwings re pproximtely 75% relesed. Figure 11 gives the PSA delivery schedule. PSA 1 (Therml) ws delivered by ACSP to MT/L on 7 June PSA 2, under construction by MT/L, is pproximtely four weeks behind schedule. The vibrtion model PSA (VM) ws delivered to MT/L by ACSP on 5 July Delivery of PSA 4, nd therefore the strt of AGE 4 nertil Subsystem testing, hs slipped bout one month, from 15 August to 15 September. t is expected tht on 15 September those trys of electronics necessry to strt subsystem tests will be vilble. PSA 4A (rck mounted) is complete except for the temperture control electronics modules which should be vilble by 15 September. PSA 5 (Clss B), scheduled for completion by 15 October, is pproximtely four weeks behind schedule. PSA 5A, scheduled for completion by 1 August, is bout two weeks behind schedule. Note: PSA Junction Boxes for erly tests of PSA 4 nd 5 will be "test", not "flight", configurtion. Fbriction of these test junction boxes is on schedule to support these erly tests. Flight configurtion will be vilble for scheduled shipment of PSA 4 nd 5 from MT/L. 6 Figure 111 shows the delivery schedule for CDU subsystems. n My 1963, MT/L issued T. D. A147 to AC Sprk Plug clling for delivery of 15 CDU's to the schedule shown below. AC Sprk Plug's current estimted delivery dtes re s follows: 4
