1. AT YOUR REQUEST THE FOttQbJIPdG I S SUBP4ITTED AS W G L E Y e S INPUT

TO PUBLICITY RELEASE BY EWAWDS ON PROPOSED Fl.I(FiHt DWOPBSmATI;BQS

2. WHEN THE SPEED OF AH AIRCRAFT A P P R M S THE SPEED OF SQWD,

LOCAL REG10MS OF SUPERSQHPC AS8 FLOW BEWELOP ABOUT THE AIRCRAFT,

P B R T I C W B L Y ABOVE THE UPPER SURFACE OF THE W I I G . THSS SUPERSOPPIC

FLOW CAUSES SEWERE LOCAL BfSTWSMNCES, WWtl TECC(Bt1CALLfl AS SHOCK

WOULD BE EXPECTED, MOST F L l W OPERATIONS ARE KEPT 8ELOV THE

SP€E@S AT WHICH THESE EFFECTS OCCUR. fQR MOST PRESERT AIRCRAFT,

THESE EFFECTS @CCW AT A W T 80 PEWCENT OF THE: SPEED OF SOW0

(530 MW).

9. AS THE RESULT OF WIND TUNNEL RESEARCH CARRIED OUT AT T H E NASA

W G L E V RESEARCH CENTER OURIMG THE PAST FOUR YEARS, A MEW WING 1 3

SHAPE HAS BEQd BEWELOPED W I C N SUBISVNTIWLLV DELAYS THE WSET OF

THESE AWERSE EFFECTS. I N PARTICULAR, THE WING AIRFOIL, THAT I S

THE CROSS SECTICMAL SHAPE OF THE WING tOQOTIP16 AT I T FWJk-4 THE SEQE,

HAS BEEN DRASTICALLY C W G E O . THIS NEW SHAPE I S REFERRED TO AS

THE MaSA SUPERCRITICAL AIRFOIL.

4. THE USE OF THIS NEW S U N Q C R f T I C A I WIM6 SWFE SMMJLD SUBSTAW-

T IALLY IMPROVE THE PERFOWWCE OF M V M U R E MILITARY aeQD

COWEWCIAL AIRCRAFT. IF THE PERFORPlARIGE RESULTS MEASUREB II W I I O

TUPBBbEtS ARE FULLY ACHIEVE0 fiU FtXGHT, I T G0Uf.D dlLLOlrd N1C;HLY

EFFICIENT CRUISE FLIGHT AT THE SPEEQ OF SUUBTO (69BWPH). A SONIC

TRANSPORT A I R P W E WOULD BE ABOUT 25 PERCENT FASTER T W PlOST

WBSORIIC JET TRANSPORTS PRESERTLV IN USE AND 20 PERCENT R4STER

THAN THE HEW AIRBUSES WW BEIXB BEVELOBEO. THE IHCREASEB SPEED

WOULD REDUCE THE TIZMSCOB~TIME~~TAL NO rab\wtsanAEenc FLIW VXMS

BY ABOUT AH MU@ COb4PABEB WITH THE TIWE REWIRED FOR BRESElT

SUBS@YIC TRAMSPORTS M U ALSO WOULD SIGP4IFECMTi.Y REDUCE THE

FlICWC COSTS, P R I M R f t Y BECAUSE OF THE WEATEW U l I t I Z A T I W OF

THE AIRCRAFT.

5. I T MIGHT ALSO BE ROTE0 THAT A SONIC AIRPLANE WITH THE NEW

SUPERCRITHCAL WING WOULD BE SUBSTAMTIALLY MURE EFFICIENT T W

A CO#BAJ?ABLE SUQERSBNPC AIRPLANE AH0 WOULD MOT PFiOWICE THE WELL

KNOWN SOHIC BOW ASSOCIATE0 WITH SUPERSON EC AIRCRAFT.

6. BECAUSE OF THE DRASICALL'P DIFFERENT MATURE OF THE BE W O W
