MILITARY GROUND SUPPORT SYSTEMS
COMMON REMOTELY OPERATED WEAPON SYSTEMS (CROWS) INTEGRATION KITS
CDMG has manufactured two configurations of the CROWS integration kits for Picatinny Arsenal since 2013 on an FFP IDIQ “build-per-print” contract. The CROWS kits are designed to mount on different remotely operated weapon systems used with various military vehicles throughout the U.S. Army. These kits consist of parts and hardware that incorporate different armament pieces onto military vehicles and allow firing and control from within the vehicle. These kits include armor plate components that require CNC machining, handling and packing.
IMPROVED ARMY SPACE HEATER (IASH)
The IASH is a mobile, multi-fueled, duct-type and electric-powered heater. Its nominal capacity is 140,000 Btu/hr. It delivers clean, heated or ventilated air to mobile shelters and other enclosures used for personnel and equipment through flexible, detachable ducts. It is capable of burning both diesel fuel and JP-8. It operates from a 120V, 50/60 Hz power source and uses 3 kW of power. The IASH operating temperature range is from -60 F (or below) to +65 F, and it can survive exposure to harsh environments, including vibration, salt fog, fungus and extreme humidity.
The IASH is designed to support various weapon systems and is deployed worldwide in combat and peacetime operations. The IASH provides heat to critical equipment and personnel in adverse conditions without interfering with other nearby equipment. This means it does not conduct or radiate electromagnetic interference, which could disrupt and possibly damage sensitive electronic systems. The IASH will withstand rail and rough-terrain transport along with other high-shock vibrations. It operates successfully in low arctic temperatures, corrosive seacoast environments and survives Nuclear, Biological and Chemical (NBC) attacks.
In addition, mobile tactical weapons systems require replacement IASHs that have the same function and weigh the same or less and are the same size or smaller than the original ASHs. This interchangeability is necessary to maintain a standard interface across the entire fleet of unique tactical weapons systems in which the ASHs are used. Additionally, the IASH includes carbon monoxide (CO) sensors and alarms and an optional NBC kit.
When manufacturing the IASH, CDMG re-engineered the heater due to a pre-engineered design defect by the original manufacturer. This defect caused a serious cracking issue with the heat exchanger. We found the defect during our First Article Testing with the heater built to the standards of the prints from the original manufacturer.
While still in First Article Testing phase, CDMG completely re-engineered the heat exchanger to correct the defect while allowing the efficiency of the heater to exceed the original requirements, moving from 120 BTU to around 140 BTU. As a result of our engineering efforts, the customer renamed the heater to “Improved” Army Space Heater.
Over the course of 10 years, CDMG produced 5,605 Army Space Heaters and twelve Chemical/Biological Protection Heater Interface Kits (CBPKs).
