The technical and operational feasibility of humidity control within the U.S. Air Force Aircraft Service Shelter has been evaluated. Feasible humidification, dehumidification and humidity control equipment has been tested and appropriate equipment modifications recommended. It is recommended that the existing shelter heat pump be used for dehumidification, the Dri Steem model VM2 be used for humidification and the Honeywell models H46C and H46D and Abbeon Cal model 4703-602 be used for humidity...

Some secondary item assemblies for the Army's 20-Ton Rough Terrain (RT) Crane Program have been tentatively identified as being obsolete because they appear to be no longer obtainable. New, competitive sources of supply for these items, used with the M2380, M2385, and M320 RT Cranes, are needed to keep these cranes operable. VSE Corporation reviewed 18 specific stock listed items and recommended that 10 replacement items be obtained and tested, 1 item should continue to be manufactured, and 7...

The U.S. Army has identified a requirement to rotate 20 foot and 40 foot ISO containers during loading and unloading operations using the Army 250 ton crane P&H Model 6250 and 20 foot and 40 foot Line Fast Corp. Model 7127 spreader bars. To accomplish the mission a Bromma Model EH3 Rotator was installed. The rotator is suspended by the double hook blocks of the 250 ton crane. In its present operating configuration, the spreader bar is attached to the rotator by slings. the sling attachments...

This pamphlet, developed for the DSPO, provides instructors with selected standardization case studies. One way to present the studies is to provide only the first part to a student work group (1-6 students per work group). After some period of time for the group to develop a course of action for the case and to address the discussion topics, the group should present its 'solution.' the second part or the 'outcome' should then be distributed, and time allowed for group review and further...

A prototype 18K/100 ICE Unit was tested, modified, evaluated and has a Level 1 drawing package updated according to task order requirements. The results of this effort yielded seven pretest and six post-test hardware modifications, a proposed operator and maintenance manual, and 34 recommended changes to be incorporated into a production ICE unit. If adopted, these 34 changes will give an estimated savings of 22 pounds, 0.2 cubic feet, and $4,000. 00 per unit. VSE Corporation recommended that...

This report consists of three volumes: Volume I - 15 kW DOD Generator Set; Volume II - 30 kW DOD Generator Set; Volume III - 60 kW DOD Generator Set. Government approved modifications to the military standard 30 kW Diesel Engine Driven (DED) Generator Set were made to reduce noise levels and improve reliability. Tests performed to a government approved test plan showed all design changes to be sound in concept. Further reliability testing should be accomplished after deficiencies resulting from...

VSE provided prototype manufacturing, engineering evaluation and testing services to support development of two 18,000 BTUH horizontal and two 18,000 BTUH vertical TECS air conditioners. These four air conditioners were fabricated for government testing such that comparative data could be generated and evaluated. Controls testing and run-in testing were performed on three of the four fabricated units. One unit was delivered without a motor controller and therefore not formally tested. These air...

VSE Corporation and a team of three subcontractors, developed, fabricated and delivered three Total Environmental Control Systems (TECS) (modified military air conditioners) to Belvoir for subsequent government evaluation. This developmental effort, based on the application of solid state electronic motor controllers to 18,000 BTUH GFE air conditioners, resulted in deliveries of two soft-start TECS; one soft-start variable capacity TECS; one feasibility study concerning the use of commercial...

A market survey was performed to select soft start controllers for use with the standard family of military horizontal and vertical air conditioners. Additionally, control logic circuitry was designed and a life cycle cost model was developed to show the economic impact of adding procurement costs for the controllers and control logic circuitry to obtain substantial savings costs.

VSE provided technical support to Belvoir's testing program for the 18K BTUH Vertical and Horizontal TECS air conditioners during the period of 14 March 1988 to 16 September 1988. VSE technical support consisted of participation in monthly Government reviews of ongoing testing, troubleshooting support following equipment failures and shop labor services for substituting military for commercial compressors in four (4) air conditioners. The Southcon and Keco motor controllers have each...

Reported illnesses of persons working in PATRIOT Missile System equipment shelters were investigated and found to have been caused by exposure to Hydrolyzable Fluoride (HF). PATRIOT mil spec 18,000 BTU Split-Package Air Conditioners (ACs) produced HF when their heater rod Teflon grommets outgassed upon being subjected to temperatures exceeding 400 F. A PATRIOT Support Project Office retrofit program for series '80 and '81 ACs and engineering changes to series '82 and later units eliminated the...

The U.S. Army Natick Research, Development and Engineering Center (NRDEC) is developing new Battalion Aid Stations (BAS) and Division Clearing Stations (DCS). A DCS will be twice the size of a BAS, as it will most likely consist of two interconnected BAS shelters. NRDEC requires that BAS shelter utilities be packaged to fit onto the U.S. Army M101A1 3/4-ton cargo trailer. The U.S. Army Belvoir Research, Development and Engineering Center (BRDEC) is developing the environmental control, chemical...
