TITLE: A New Piezoelectric Profilometer (Novyy plyezoelektricheskiy
profilometr)
PERIODICALs "Izmeritellnaya Tekhnika", No 5, Sep-Oct 1957, PP 15-16 (USSR)
ABSTRACT: The subject instrument, profilometer "AB" was developed at
the Moscow Institute of Aviation-Technology (Moskovskiy
aviatsionnyy tekhnologicheakiy institut) under the direotion
of I.V. Dunin-Barkovskiy. The instrument is designed for
measuring the roughness of 5th to 12th class surfaces by the
standard i,rOCT-2789-51". It features a piezoelement con-
aisting of two ceramic barium metatitanate laminae which are
glued together and a sapphire feeler with 10 microns radius
of tip. Barium metatitanate is stated to be highly piezo-
effective, stable, independent of temperature in a wide temper-
ature range, and possesses a high mechanical strength. These
properties make it highly-suitable for electromechanicg-.1 pro-
filometers. The design of'the instrument is described in
detail. It eliminates the input and output transformers and
the integrating contour. The four measurement ranges of the
"AB'' profilometer are: 0-0.1 microns, 0-0.4 microns, 0-1.6
Card 112 microns, and 0-6.4 microns. It is claimed that the measure-

A New Piezoelectric Profilometer 115-5-6/44
ment errors do not exceed 1 18%, while the errors of the
Philips profilometer redch t 25%, of the IIKB-711 + 15%, and of
~the 1111'q-211 t 25%. The instrument is applicable ior measuring
the surface finish of flat parts, cylindrical parts in dia-
meters from 19 mm up, the inside of cylindrical parts in dia-
meters from 36 mm and up to a cylinder depth of 300 mm. The
instrumentf including the motor drive, weighs 11.8 kg and is
fed from 220 volt a.c; mains.
The article contains 1 diagram.

ABSTRACT At the present sta_-~-e ofxocket construction velocities are realizab-
1e which are not inly sufficient for the orbital control of arti-
ficial satellitez,but also for a flight to the moon.The computation
of the trajectorl to themoon is reduced even in the case of the most
simple formulation of the problen,to the circular(?) limited three-
bod~, problem unsolved in mechanics. From 1953 to 1955 the M7:thema-
tical Institute of the Academy of Science in the U.S.S.R. by using
electronic high-speed compators systematically investigated the ria-
thematical problems connected with a flight to the moon.The prescnt
paper contains the most important results obtained by these inveoti-
gations.
The ec,:qation of motio First the problem is ret.uced to the circular
limited three-body problemieartli,,-loon,rooket.The equation of this
problem have an energy integral in a certain system of coordinates.
Therefore the problem can also be approached from the point of view
of energeties.Jakobits integral makes it possible theoretically to
solve the problem of the minimum velocities necessary for reachinE
the moon.The trajectories correoponding to the theoretical minimum
velocities are of no practical value,as,for along time, they remain
nearly elliptical with a focusing point in the center of the earth.
Before reaching the moon the rocket muat perform hundreds and laore

the proviuus chapter are totally- insufficient for the parpose of
reaching the moon with one sirZle revolution.The noun exercises prac-
tically no influence upon the firat rcvolation of tho rocket."L'he
author makes use of this circumatance for the approximative compu-
tation of the jainimum velocities.

ched from tic earth. If such a proJectile,in the occasion of its
first revolution,enters the splhere of action of the moon,it ia bound
4o leave this sphere again.The moon therefore cannot capture such a
projectile and it is impossible to nrovide the moon with a a--telli-
te with only one revolution and widiout using a motor.Thin,however,
does not apply only in the case of an approach to the moon on any
traje:,-tory.In p.-inciple the production of a tenporarily revclvini;
moon satellite without a motor it woald ha-
ve before to revolve round the earth sufficiently often.The next
chapter deals with a method of aUroximation for Lhl* investigation.

For a flight round the moon initial conditions can be computed t1hich

ABSI=T At the present rtage of development in rocket construction it is really
possible to attain velocities which suffice for a flight to the zoo&
. but also in consideration Of only the most important of the forces ac-
ting upon the rocket, the corrospoRing dynamical problems is reduced
to the tree-body problem not solved in mockanics, For the determination
of the flight path concerned and the influence exercised by the in4tcura-
cies of the initial data slectroxie computers are used. The proseni work
discusses the main results of the solution of the problems conoornid.
Falling on to the moons it was proved rigorously that the minimum
