Aerospace and Defense Publications
Some of the more recent aerospace and defense Case Studies, Solutions Briefs, Technical Articles, and
Technical Publications MSI has performed are highlighted below. For older publications please refer to the list at the bottom of this page.
MSI endeavors to make most of our publications
available in PDF format for you to download at your convenience.
However, due to certain Copyright and distribution restrictions on
some publications, we can not provide a PDF file for you to download
and therefore request that you fill out the corresponding request
form at the bottom of the publication page.
We apologize for any inconvenience this may cause.

Helicopter Hoists and Winches
One of the key uses of helicopters for both civilian as well as military purposes is for moving and hauling cargo in a short time-frame, or into awkward locations. MSI has become skilled at performing
strength-of-materials calculations associated with winch and hoist components in such aircraft applications. One of the issues which has become clear in MSI's investigations is that, in spite of some of the excellent
hardware already in existence for helicopter winches and hoists, significantly increased cargo capacity is possible, and at the same time the weight of such advanced hoist systems could be reduced.
Key factors that MSI identified which may be brought into play to accomplish this in future designs include composite structural materials, improved gear tribology (through coatings and/or lubricants), improved
cable materials, and better "systems" integration of the hoist supports with the aircraft frame. MSI's strong materials background as well as its superior analytical tools (such as ANSYS and Pro/Engineer)
are allowing rapid progress in this area.

Penetration Analysis Example
Projectile design projects involve the accurate simulation and the subsequent optimization of the projectiles’ parameters prior to conducting rigorous testing. MSI has combined experience
with the proficient application of Pro/Engineer, ANSYS/LS-Dyna, and CTH Hydrocode software to meet the challenges of projectile design. MSI models the target and projectile geometries, and then translates the
solid models into the LS-Dyna or CTH software to perform extensive analysis of the designs.
The simulation that is depicted by the figure below illustrates a non-lethal projectile which has impacted a target at one of many different velocities. MSI predicted the deformations of the projectile
and the target over a wide range of terminal velocities, and hence improved the accuracy and effectiveness of the projectile at distances far in excess of competing designs, yet the projectile remained non-lethal at close
ranges. The analytical results guided the design process, which drastically reduced the project’s development schedule and costs.
