The invention. described herein may be manu
factured and used by or for the United States
Government for governmental purposes without
payment to me of any royalty.
I This invention relates to a jet engine container
suitable for supporting and protecting the engine
while in transit or storage or at any time prior
to installation on the aircraft.
The primary object of the invention is to pro
vide a cylindrical engine container capable of
being made substantially air-tight and having
means therein to resiliently mount an engine,
particularly one including two or more mounting
2
Considering now the principal view (Fig. 1) of
the drawings, the engine container comprises a
closed-end cylinder supported by a pair of ?oor
contacting skids or rails. Means inside the con
tainer-are adapted to resiliently support a hori
zontally disposed jet engine (not shown). Con
sidering the drawings more speci?cally it will be
seen that the container l is made of two similar
semi-cylindrical shells 2 and 3. The lower shell
2 comprises a pre-shaped semi-cylindrical steel
sheet welded along lines 4 and 5 to conxex semi
circular end plates 6 and 1 including narrow mar
ginal ?anges integral therewith.
Similarly the
upper shell 3 comprises a pre-shaped steel sheet
welded along lines 8 and 9 to semi-circular end
and wherein the mounting means includes lon
plates Ill and II including marginal ?anges ex

the upper horizontal bight portions thereof are

lower and upper metal attaching flanges 36 and

spaced rubber blocks or cushions 38 and 39. The
lower ?anges 36 are bolted onto“ the respective
brackets 32, 33 and 34 and the upper ?anges 31

as shown by the relatively larger opening there

As may be seen. the engine is supported by two
trunnions on each side at diametrically-opposite
points. Thus, if the engine bearing beam 41 at
one side tilted slightly in one direction of rela
tive rotation about its center as the rubber
cushioned supports ?exed and the engine bearing
beam 42 at the other side tilted slightly in the

which total six in number. Welded on top of the

container walls at the parting line of the shells
2 and 3. As seen in Fig. 3 these beams orbearersz
are of box section but any one of numerous cross
strain would probably break off one of the en

connecting members 41 and 43. These connect
ing members eliminate or minimize the random
independent movement of the engine bearing
beams under shock, impact or careless handling
of the container. Under movement, the engine
sectional shapes may be employed.
