MAJOR ACCOMPLISHMENTS
MX MISSILE
Successfully designed Defense Suppression System of the MX Missile (Finite element
vibration and stress analyses, MSC/NASTRAN, SDRC/Supertab & Geomod, ANSYS,
Martin Marietta Aerospace).
PC BOARDS FOR CANNON BULLETS
Designed a set of PC boards used inside the cannon BULLET for its guidance-system that
can withstand 12,000 G's. It was very difficult to design these due to the size and design
requirements (Finite element stress and vibration analyses, Martin Marietta Aerospace,
Project: CopperHead).
PATENT
Invented a special rotor-centering spring that saved an aircraft gas turbine engine (MPSPU)
from repeated failures. A patent has been submitted to the Patent Department of the Allied-
Signal Aerospace Company and is pending.
CYCLIC SYMMETRIC VIB ANALYSIS OF BLADED DISKS
Created a 3D continuous solid model (with brick elements only) of EFA Compressor blade
and a slice of the disk with identical node locations for repeatable side one and side two.
The finite element code NASTRAN, which is very strong in cyclic symmetric static and
vibration analyses capabilities was utilized.
DEVELOPED COMPUTER PROGRAMS
Developed two computer programs, e.g., FREQUENCY RESPONSE ANALYSIS and
TRANSIENT RESPONSE ANALYSIS of three dimensional general systems that can have
damping, gyroscopic or coriolis forces, and circulatory forces.
Wrote a Fortran computer code MMIAS to calculate the mass and inertia properties of any
general axisymmetric solid that can have cross section with void areas. The program is now
a part of Garrett (Allied-Signal) Stress Library for general use.
Developed computer programs using Direct Matrix Abstraction Programming (DMAP) of
NASTRAN.
