mm stumps. Their position can be modified to realize every configuratIon of the
tube. The eeotional dimension of the tubs Is 300 X 190 mm. It Is prorido4_ with
a vacuum Pump of 1-7 kw and a residual vacuum of 0-3 M H8, and a 0.7 kw air com-
pressor supplying 7 atm. These installations supply a maximum vaauum of 2 mm Hg
and a maximum pressure of 6 atm, correopondIng to a m&x1mum theoretical Mach Num-
ber of M - 1.45 and M2 - 5,37. The main problem consists in an adequato measur-
Ing of the aerodynamlo parameter. The shook tube was designed to guarantee an
average operating time of 5 - 10 milliseconds- In order to use -the shook tub*
for qualitative research, it became necessary to work out methods of measuring
the aercdynamic parametare with a short response timo which should represent a
fraction of the above-mentioned minimum operation time. In order to accomplish
the measurement of a great number of physical parwafters, the shoak tube was
equipped with the following InstallatIonss a) Apparatum for M#asuring the inl-
tial static parameters of the air In the shook tubei b) control relay with oon-

A method of measuring D237/D301
The operation principle is described as follows: 'the RC oscillatort
the am the dephasing circuit produc two sinusoidal
plifier and
voltages of the sa)ne frequencyg,dephaaed to 908 , which are applied
to the pairs of the deflecting plates of the cathode tube. Thus,
...the electronic spot describes a circle on the screen. Before re-
leasing thy phenomenon in.the shQck tube, the.intensity of the spot
is very low,, being Ibelow,the visibility limit. The moment the
shock wave passes in*front of the wave detectors, two electric sig-
nals are produced which are amplified and processed by two chains
of amplifiers,which act on the electronic relay; the relay controls
*the lighting and the extinguishing of the cathode tube spot; The
electronic relay also acts on the modulation circuit, which gradu-
ally reduces the amplitude of the deflection voltagep. Thus the
electronic spot does not move any more on a circle, but describ6s
a luminous spiral arcp which is photographed. The time variation
of the-amplitudes is determined according to
4p 2nf. At,

cation channels, representing 0.03 % for a measuring interval of
1,000 microsec; and e) errors appearing when measuring the dis-

errors due to cases a) And b) may be kept below 0.1 5. To these
errors may be added certain differences produced because the shock
