Progress TO BE Reported.
The conferences at Langley Field viii
enable the national advisory committee
for aeronautics to report to the repre-.

problems and to receive suggestion as
to investigations to be made during the
coming year to solve the most pressing
aviation problems Of the day.
The discussions listed for tomorrow
will include:
Analysis or the committees investiga.
lions during the year on the determine
ton OF the distribution of aerodynarnic
loads on wing surfaces, tail surfaces ana
fuselage. The investigation so far mas
been conducted on military types OF
aircraft and there viii be discussion OF
the desirability of extending this In
vestigation to incltEe commercial types.
Study OF the cowling and cooling
problems In connection with the use
of radial air.cooled engines on multi
engined airplAnes, with particular ref
erence to the position of the engine
nacelle In relation to the wing.
Study of the characteristics Of an
airfoil section as affected BY Slots,
boundary layer control and warped
surface to improve the. safety factor In
aircraft by improving the lit ana nom
spinning characteristics. ,.,.
view to increasing the. efficiency OF
propellefs, including a study or pro-
peller interference and high-speeo pro-
pellers.
Brake Problem to be Studied.
The problem of taking off and land
Ing of airplanes as affected by the use
of brakes, tail wheel and different
methods of absorbing landing shock.
General study Of the further reduc-
ton of the parasite drag OF airplanes'
The problem Of the fiat or the I'M
controlled spin. -,
ing aircraft engines.
