RAH-66 Comanche, Torque Limiting Device
The Comanche RAH-66 reconnaissance and attack helicopter was developed by Boeing and Sikorsky for the US Army. The program entered engineering and manufacturing development (EMD) in June 2000, which required the construction of nine aircraft in addition to two prototypes. In an armed reconnaissance mission, Comanche could recognize and identify targets and digitally transmit the… [Continue Reading]
Shunt Resistor Bank (SRB) Heater Plates for Satellite Application
Peregrine, in collaboration with its Aerospace customer, undertook a design, manufacture and testing contract to produce a set of shunt resistor bank heater plates for a satellite application. Specific to this application, is the requirement to dissipate 900 Watts of thermal energy into space. Due to the environment of space, this thermal load had to… [Continue Reading]
XMM Newton Satellite RGA Structure
The XMM Newton Satellite carries three telescopes to measure x-rays generated from extremely violent events from distant celestial objects. The XMM Satellite has been placed in a highly eccentric orbit reaching about one third of the distance to the moon, allowing the telescopes and detectors to operate unencumbered from the earth’s atmosphere with unprecedented sensitivity.…[Continue Reading]
Process Development/Process Verification
Nuclear Metals of Concord, Massachusetts requested that Peregrine assist in developing processes in parallel with their casting development of beryllium aluminum alloys. Primarily the interest of Nuclear Metals was for Peregrine to develop and confirm that the processes involved with attaching mechanical fasteners/threaded inserts, adhesive bonding, and the ability to press and shrink fit…[Continue Reading]
Cold Finger for GBI
The Ground Based Interceptor (GBI) mission is to intercept incoming ballistic missile warheads outside the earth’s atmosphere and destroy them by kinetic energy. The GBI consists of an Exo-atmospheric Kill Vehicle (EKV) launched by a fixed land based booster. During flight the interceptor receives information from battle management, command, control and communications to update the… [Continue Reading]
Heat Exchanger with Low Resistance Leakage
At times, under certain medical conditions, it is important to control the overall temperature of the body. By lowering the temperature, there are certain medical advantages in order to slow down the recovery rate or response rate from a patient. This is done by inserting a catheter within the central venous system of the patient… [Continue Reading]
Parabolic Reflectors for Passive Microwave Radiometers
Our people assisted with the Advanced Microwave Sounding Units (AMSU-A & B) space flight instruments, which were multi-channel passive microwave radiometers that measured global atmospheric temperature profiles from the advanced TIROS-N spacecraft. Aerojet Electronic Systems (now Northrop Grumman) was responsible for the delivery of the AMSU-A to NASA / NOAA. The AMSU-A system provides information… [Continue Reading]
The Development of the Liquid Flow Through Modules for the F-22 Common Integrated Processor
Our engineering and manufacturing people assisted in the development of Liquid Flow Through (LFT) for the Air Force’s F-22 Fighter Aircraft. These LFTs were used in the aircraft’s Common Integrated Processor (CIP). Printed Wiring Boards (PWB) were laminated to Liquid Flow Through (LFT) heat exchangers creating Line Replaceable Modules (LRMs). The LFT heat exchangers were… [Continue Reading]
