OPI value indicates the moment when the wear- changes from the fricticn
stage into the abrasion stage. It may happen that an oil. unfavorably
valued on the four-ball apparatus, stands up well under operational condi-
tions, because there are cases where l4quid frict'on exsts, so that 'the
wear-inhibitirg properties of the oil do no', appear. The load applied,
to the balls is selected from the geometrical progression with the

The balls can be used only once, and fresh oil is to be taken for each
test. The test conditions are international as well as the determination
of the OPI value, but if this value alone is applied without the- ;P,,
value.for the welding load, as it is the case abroad, the index:@,f the
wear-inhibiting properties-of lubricating oils is insufficient, The
Introduction of the standard mentioned concerns the indices for wear-
inhibiting properties of commercial lubricating oils and especially
of heavy-duty oils withwear-inhibiting additions. The standardization
of P,,,and OPI warrants a control of these properties during storage
and use. Designer5 of new machines can thus specify the proper oils
increasing the service life of these machines and achieving savin.gs in,
repair and repiacement costs. There is 1 Soviet referen:@eo

ABSTRACT: A method of design calculation of statically indeterminate
frames c'onsisting of rectangular cross-section beams is inves-.
tigated for cases of frame loads beyond the elasticil@mit.
The method suggested evaluates approximately the influence
of the elastic-plastic zones acting as variable- rigidity areas
on the distribution of the bending moments and on the calculated
displacements which are determined with the aid of Mohr' s
integrals. It is pointed out that in these calculations it is
important to select properly a statically determined system for
plotting the curves based on a unit force. A specific calcula-
tion sample of a two-story (six times statically indeterminate)
Card I/Z frame is investigated for three different degrees of loading

ABSTRACT: The article discusses ways of operating a Tu-104, when one of the
engines fails during takeoff, and emphasizes those peculiarities
.
pi ston-engine aircraft
which distinguish this jet plane from a
attempting a takeoff under similar conditions. In jet planes the
dependence of weight on speed is smiLUer, and so is the tendency of
the jet aircraft to yaw and to bank. Ddring the test with the Tu-104,
the flying weight was increased up to 72.5 tons. The.engi,ne was cut
Off either one secondafter takeoff, or one and a half seconds.prior
to takeoff; in this latter instance the loaded,weight was only 68.5
tons. The whole operation was registered by instruments.
M. Mogilevskiy, Candidate of Technical Sciences,proposed reducing
the takeoff angle of the flaps from 20 to 100 in order to increase
the rate of climb as soon as one of the engines failed. Since a

Piloting a Tu-101, During Takeoff with Only One Engine Running,(cont..)
with a 200 flap angle provides a considerable lift reserve, a reduc-
0
tion of the flap angle to 10 maintaining the.same speed, sti11
retains the same takeoff run.@ The excess' speed above the,stalling
speed in this case is adequate, amounting to 35 lak/hr. Tests have
proven that by flying at a speed of 300-320 kR/hr without banking
and with only.one engine running, the additional resistance due to
sliding decreases the climbing speed by 1.2-1.3 meters per second-
this is avoided when the Tu-104 climbs with a 30 bank to the side
of the running engine. If flying with no bank and with one engine
idling, the pressure onthe respective pedal is about 80 kg. A
bank of 10 to the side of 'the running engine decreases the pressure
by 30 kg; and almost no pressure exists when the bank is around 30.
If this bank is increased (e.g. up to 50) the aircraft tends to
turn in the same direction and thus-the opposite,pedal must be.
stressed to maintain a straight movement; this'again:should not be
violent: the bank to the sicle,of the- idling engine shouU
not exceed**17:-1.50. The retraction ofAhe-landing gear-.takes-about
30 seconds. SinceAhis operation decreases the,climbing dpeedj it
is advisable if one engine fails.)to start retracting the gear only
after.the planeneaches an altitude of 70.-80 meters. In case one@
engine fails, the takeoff run should be increased up to 310-315

kinetic and the potential energies of the flying plane@ Vhen the.
plane reaches an altitude of 70-80 meters, it should be levelled off
and the speed increased to 360-360 luan/hr, Ohly after the situation
is completely under control, should the pilot prepare for landing
and getting rid of excess fqel. Tests with the Tu-104.prove that
climbing is possible with a loaded weight up to 72.5 tons. The
crews should be trained under actual conditions also as far as
the temperature is concerned, e.g., at a temperature of 150 to 200
Centigradethe loaded weight should be 60-62 tons, and at a temperature
of 0 to minus 5 (Centigrade) 66-67 tons. The failure of one ofthe
engines should be simulated by switching the engine to an idle position
first at a speed of 310-320 km/hr, later at a speed of 280-290.1cm/hr.

TEKIN The author discusses the economic aspects of air transport and de-
scribes a number of flying tests carried out by the GosNII GVF (State Sciientif!,@,
Research Institute of the Civil Air Fleet) on Tu-104 aircraft., The purpose of
tsstz was to increase the flying speed of aircraft which depends large17 on ths
climb-ing p=arformanc-a and on the acceleration. During the climb the air-craft
gains v@rtical speed from the surplus pull which in turn depends on the flying
Epeed. The dependence of the surplus pull on true flying,speed on -various alti-
tudes(Fig. 1) shows that the steepest rise of aircraft corresponds to them maximum
climb. Figure 2 shows the dependence of the vertical climbing speed of Tu-1o4
on the true speed at varying altitudes. The most favorable speed at 10,000 m
a tude is 7'30 km/h, i.e. 30% higher than on 'he ground. The best climbing pel-
formance was achieved by navigation towards the echelon at operating speed whi,-;h.

Abstract The.author studies the effect of variation.of,magnetic
and physical factors on the time,needed to change a,
magnetic toroid.from a condition of.residual flux density
to the opposite condition of saturation flux density.
This "switching time" is found,to consist ofthree com-
ponents', which depend,.first, upon the eddy,current
losses,@second, upon the demagnetizing action of the
current in the outlet winding to which.is coupled the
load' and third, upon the delay in the magnetizing :
circuit. When eddy.currents are absent, themagnetic
flux in a rectangular hysteresis.loop material increases
in direct proportion to the time. Eddy currents.change
