REPORT ABSTRACTS

CONFERENCE PUBLICATIONS (CP)

Compilations of scientific and technical papers or

transcripts arising from conferences, symposia,

special lecture series and seminars, and other

professional meetings that NASA elects to publish.

The series is subdivided into low-numbered and

high-numbered subseries conference publications.

The low-numbered subseries are those compilations

whose enduring value of content warrant significant

editorial contribution prior to distribution. The

high-numbered subseries are those compilations for

which speed or control of dissemination is a prime

consideration.

REFERENCE P UBLICATIONS (RP)

Compilations of scientific and technical data and

information deemed to be of continuing reference

value in particular subject areas or disciplines.

TECHNICAL MEMORANDUMS (TM, TMX)

These documents record scientific and technical findings

that d o not warrant broad dissemination or that cann o t

be given broad dissemination due to security or

restricted-audience considerations. This series includes

quick-release rep o rts that typically contain preliminary

data and were designated TMX until 1978, when the "X"

designation was dropped.

Lateral characteristics indicate that the spoilers ape generally adequate for lateral control. In general, the spoiler effectiveness Increases with increasing angle of attack, increases wtth increasing flap deflections, and Is Influenced by vent llp geometry, In addition, the data Snow that some t w o-dinenstonal effects on spotlep effectivenes s are reduced in the three-dimensional case.

TECHNICAL PAPERS (TP)

These documents record the findings of significant work

conducted by NASA scientific and technical personnel.

Technical Papers are the Agency's counterpart to pro-

fessional papers and, therefore, are released only after

a professional review controlled by the originating

Headquarters or installation office. For documentation

purposes Technical Papers are preferred over professional

journal articles because they have less stringent limita-

tions on manuscript length or number of figures.

ABS : Five pane l s backed by a c l osed cavity we r e st udied expertmenta]ly and ana l ytically to dete r mine the noise transmission Cha r acte r istics of the coupled panel-cavity system. The closed cavity was studied both with and without fiber - glass lining to p r ovide etther an ad s orbent o r a r eve r berant acoustic space.

The effects on noise r eduction of cavity absorption, measu r ement location within the cavity, panel mass, and pane l st i ffness we r e examined. Resu l ts indicated that both m e asu r ement ] ocatton and abso r ption in the cavity have significant effects on the noise r eduction. Increasing panel mas s improves the noise reduction at almost all f r equencies, and Increasing pane] stiffness improves nose r eduction below the fundamental res on a nc e f r equency. A simple, on e dimensional analyti c al mode l was developed whi c h provided go o d agree m ent with the experiment al resu l t s.

CONTRACTOR REPORTS (CR)

These documents record scientific and technical findings

are considered desirable for release by NASA. They are

subdivided into low-numbered and high-numbered subseries

contractor reports. The low-numbered subseries are

similar in quality to NASA Technical Papers and are

produced and disseminated in the same manner as NASA

Technical Papers.

The high-numbered subseries do not meet the same critieria

as the low-numbered subseries although they contain new

technical information. They are produced and disseminated

in the manner of NASA Technical Memorandums.

The trade study considers aspects of using either an analog, incremental type special purpose computer or a general purpose computer to perform critical autopl l ot computation functions. It also considers aspects of integration of noncritical autoptlot and autothrottie modes into the co m puter performing the critical au t oland fun c , tlons, as compa r ed to the fede r ation of the noncritical modes into either a sepa r at e Computer or with a R-N a y computer.

The concept utlilzed was a definition of an overall societal objective for the very long run future. Withln a f r amework s o defined, a set of s cen a rios by which the future wl]i unfo l d a r e then written. These scenario s provide the de L ermln a nts of the a l r transport Industry operations and accordingly provide an a ssessment of future fuel requirements. T he second pa r t was the modellng of the industry in terms of an abstracted set of va r i a bles to represent the overall industry performance on a macro scale. The nedel was validated by testing the desi r ed output va r iables from the model wtth historical data over the #ast decades.
