 Rugged Military Grade
Bench Top / Bulkhead Mount Systems
Chassis Plans Rugged Bulkhead Mount (Bench Top) computer systems follow many of the design rules used for the well regarded Military Grade Rackmount Systems. These enclosures are designed from inception to be used in rugged hostile environments and may be flight qualified. Constructed from high strength 5052 aluminum alloy, they provide a solid base for installation of long life industrial mother-boards or single board computers/backplanes, enterprise level hard drives, high quality power supplies and mission specific I/O cards. The use of such features as stainless hardware, self locking hardware, tailored card hold downs, all contribute to reliable trouble-free deployment into virtually any mobile, air-borne and shipboard environment where light weight and small size are important.

We have found that most of our military customers require some form of customization. Chassis Plans has the capability to provide existing designs with simple modifications through clean paper designs built entirely to a particular specifications. The following showcase demonstrates some, but not all, of the custom designs we have provided into the military community. These systems are all available for sale as is or as the basis for a design appropriate to your system requirements. For more customer examples, see our Custom Showcase and Custom Design Capability pages.
This design challenge was for a rugged mobile military application which required an LCD with features such as very high resolution, daylight visibility and protection from sudden shock - in a compact form factor. Chassis Plans started with two solid aluminum billets and milled a high precision enclosure with the two halves mating with an o-ring seal meeting IP67. The 17-inch LCD started as best of breed with 800:1 contrast. This LCD was further enhanced with circular polarizers and a high transmission (88%) touch screen with an anti-glare hard coat. These components were optically bonded to the LCD usingindexmatched adhesives. Bonding prevents dirt and moisture between the filters and display.  Bonding also significantly ruggedizes the LCD, reinforcing the glass and minimizing shock which might damage the display. The bond will also hold the glass together should the display be significantly damaged such as from a bullet or explosion. The finished product came in at 15 lbs.
The enclosure is manufactured from high strength 5052 aluminum alloy with heat dissipating fins milled into the back. Stainless hardware and self locking fasteners were used throughout. The display is highly visible even in direct sunlight. The LCD controller was modified to scale a 1600x1200 image input to a 1280x1024 native resolution display.

A Fortune 500 aerospace and defense contractor required a controller system for an airborne ultra high resolution panning camera system mounted in a C21 Lear jet. As this is flight qualified hardware, there are strict requirements for human factors, flight crew safety, structural integrity and crash worthiness. Chassis Plans designed and manufactured a rugged compact system to house a Micro-ATX motherboard, slim slot-fed DVD/RW, and two canister mounted 2-1/2" form factor solid state drives. Wiring was low smoke halogen free for fire safety. External cable connections are through Mil-Circular locking connectors. Two fans cool the system. Tailored plug-in card retention assures the cards stay seated regardless of flight vibration and landing shocks. The system is constructed from high
strength 5052 aluminum alloy. Stainless hardware and self locking fasteners were used throughout. Configured weight is a low 19.1lbs.

Northrop Grumman required a rugged computer system
to build a Digital Voice Recorder for use aboard
Navy ships. The system records virtually all audio
traffic on the ship including radio traffic, PA,
and bridge conversations. The rack system is designed
to meet Mil Spec 901D, Grade A.
Included is a 19-slot PCI Express backplane and
dual Xeon System Host Board, four hot swap Ultra
320 SCSI drives, dual DVD/RW drives, and redundant
power. The front mounted Touch Entry Device provides
system monitoring and control.

Spawar came to Chassis Plans to design a Mil Spec
chassis that would be light, extremely rugged,
adaptable, and able to satisfy the rigorous shock
and vibration specification in 901D. The "Rock"
was the result.
This is an aluminum and stainless enclosure providing
redundant power, 4 5.25" external drives,
2 3.5" external drives, and 2 internal 3.5"
drives. Both Intel and Sun motherboards can be
accommodated. The chassis passed Mil Spec 901D
(Barge Test). If you are not familiar with the
Barge Test, go here for some entertaining video (Large File - 27Mb).

 Raytheon required a quantity of small enclosure
and cables to house an F18 radio controller in
a ground application. Chassis Plans leveraged
an existing design to engineer the enclosure.
Utilizing previous art allowed for a low engineering
cost and quick turn on the project.
L-3 required a very rugged 4U enclosure
for their JRE-DLT program. The system required
that two custom PCI backplanes be installed
with XPT Dual XEON processors. One side
was configured as a Windows XP Client and
the other side was running Sun Solaris as
a Server. The chassis provides a redundant
power supply, two hot swap hard drives,
and two DVD drives.
A custom rear panel and front panel insert
were developed. A custom power control PCB
was also developed to provide a time delay
for system shutdown to prevent disk corruption.
The system was ruggedized for installation
in a transit case for battle field deployment.

Lockheed contracted with Chassis Plans to design
and manufacture an LCD/Keyboard combination for
use aboard nuclear submarines. The principle use
is for officers to be able to connect to both
the secure and non-secure systems from their quarters.
Included is a 17" TFT LCD, full feature keyboard
and glidepoint mouse device and two USB ports.
Mounted inside is an Icron USB hub extender allowing
the keyboard, glidepoint, and two USB ports to
interface via Cat-5 cable with a server anywhere
on the boat.
The challenging specification included footprint
and size constraints and a weight limit of 18lbs.
Chassis Plans delivered a system weighing only
12lbs much to the delight of the customer.

A large defense contractor specializing in tactical
ground control shelters required a rugged diskless
system for Unmanned Aerial Vehicle control. Time
to delivery was critical.
Chassis Plans leveraged an existing COTS design
to quickly and inexpensively meet the requirement.
Starting with the D3Chassis,
we shortened the chassis to 18" and designed
a new front panel to maximize cooling flow. The
chassis accommodates an EATX motherboard and a
redundant 2U power supply. Three 90mm cooling
fans and generous chassis openings assure the
installed components are well cooled.

A military customer required an ultra high resolution
LCD display / keyboard but had a height limit of
1U. In addition, there was limited depth available.
Chassis Plans performed by modifying our standard CPCSD1-17 Clamshell Keyboard LCD to incorporate the Samsung
LTM190 panel with a proprietary high performance
LCD controller. There is no 1U keyboard LCD display
with a larger monitor or higher resolution. |
A
major defense electronics manufacturer approached
Chassis Plans to design and manufacture the
enclosure for their sophisticated high speed
switch. The system houses 3 hot swap modular
cards, rear mounted CPU module, dual hot swap
power supplies, 4 hot swap fans and an internal
backplane tying all the electronics together.
Several innovative design features were incorporated
to enable the system to meet specification.

A defense customer required a light weight 1U LCD Display
/ Keyboard to fit in a Hartig travel case. The requirement
was a weight less than 22 pounds and an installed
depth less than 20 inches. Chassis Plans exceeded
the design requirement by producing a keyboard weighing
19.6 lbs with an installed depth of 19 inches. There
is no lighter or shorter keyboard on the market
with these features.
Note: This display is in production and available
for sale to other OEM's. |
A major supplier of battlefield qualified systems
required a continued supply of the Appro 4408 chassis
which Appro no longer offered. The specification
from their military customer did not allow for another
chassis to be substituted. Chassis Plans exactly
reproduced the Appro 4408 chassis dimensionally
and functionally. The chassis looks exactly the
same. Turn around time on the project was a short
5 weeks.
Note: This chassis is in production and available
for sale to other OEM's.
