=zealotry ploys a very isportant role in aircraft
eezetructicn. Peoduction of rodern aeroglanes is unthinkable with-
out ueing e. vest -variety of syntbetic materias wad plestics.

ere asobeina node or a timber plastic. Combined 'with otter ateetala
it io used for the interior of the new passenger planes fn-104,
S1-181 in-10 axd Tu-13J.
CPYRGFE In modera aircraft so-called foam plastics awe extensively nallap
;4ereinbt of ehich ia eremy tines nsaller thee even tho very light
mete/ nnemestma. Due to their good beat and souad insulation pro-
perties, they canto used as fillers for internal walls and panels.
Uhen making closed volume out of sheets, for instance control
Tunders, it is frequometly almost impossible to ensure adeqgate
riffidity and in this come self-Toaning ylastics axe very useful.
Intronuction or a certain en:entity of such plastics into a closed
volume end subseqgent 'denting ensures unifonn filling of the entire
voleee, a stroae bond of the foam layer with the metal and a high
eigidity of the desien.
By weaning foam layore with atiffenteg elements "araoared
fonee layere" are cbteined in wbich veneer elass-textolite and vari-
ous sheet retelo are used. Such reinfore4 foam layers are succeas-
fully used as fill.= in pane/o fee. eith veneer in the pact/anger
aircraft Te-104, Tu-114, ii-18; Ia additioa to increased rigidity
ma strength, these materials ensure a conaiderably reduced weight.
It is well know tent the problem of reducing the 'weight of
aircraft is one of the met acete in eviation engineering. Reduction
by even 0.02 g of the snecific weight per cubic centimetre of the
foam plestic laud in the above mentioned aircraft would enable the
Bevies of bundreds of kg of weight in very Large aircraft like the
Accor di to Soviet Civil Air Line data reauction of the
'might of a passmeger aireraft by only 1 ka produces an annual economy
in tile operation of the machines of about 2000 roubles. Consequently
the reduction in weight by 300 kg for 100 aircraft leads to an
aroma economy of about 60 million rouble

Application of glued joimts in the manufacture of helicopthr
blades enabled ialaroving the quality ant increasing their lifetime
to doUble and even mowe.
Local stress concentrations whieh occur around rivets, weld
spots, etc., distribute uniformly throughout the surface of tha
joint in the CE30 of glued joints and thereby enables sipplitiection
of the design end ensures a surface ?lash is smoother than that of
rivetted, welded or soldered joints.
New types of synthetic resins, particularly epoxide resins,
permit using more economic systcas of doping aircraft,. the coatiag
(gm be ea:plied directly to the metallic sheathing eittaut using
2ny priwnr (oil varnish ow glyptal zinc chromate primer). Use of
such doping systems In modern aviation permits saving of hundreds
of tons of prineri, and dogeas of to of vegotsble oils required
for manufacturing then.
It-is not possible to enummmte uithin bort article the
gl:eat variety of synthatic,mnteriels used for aircraft construction
but the few exaTemlas show clearly the impprtance of plastics and
