美國陸軍計畫改進“斯特瑞克”裝甲車
2012-08-01
[據法國《防務宇航》2012年7月31日報導]美國陸軍工程師正在對“斯特瑞克”裝甲車設計和實施重要的改進,主要工作包括裝備更強大的發動機、改進懸掛系統、提高車載電源功率並增加下一代聯網和計算技術。
美國陸軍現有的“斯特瑞克”裝甲車超過了4187輛,採用了10種不同的底盤和7種不同的雙V底盤設計。“斯特瑞克”工程轉換提案的第一階段將首先進行初步設計評審並生產樣車。階段1包括一系列對平臺的關鍵改進,還包括提高整車的性能、資料處理能力和車輛電子設備的性能。
第一階段的工作主要包括提高電源功率,將“斯特瑞克”現有的570安培交流發電機替換為910安培的交流發電機,並將現有的350馬力發動機替換為商用現有的450馬力發動機。
“斯特瑞克”工程轉換提案還包括改進車體的懸掛系統,能夠在增加整車重量的同時提高車體機動性,同時改進車內網路,通過為平臺配備“數位化中樞”提高車內成員的資料和視頻共用能力。
車內網路包括可控交換機、智慧軟體、顯示幕和處理設備,在車內平臺之間實現保密、可靠的資料共用,並能減少車內未來系統綜合元件的尺寸、重量和功耗。車內網路將採用“開放式體系結構”,意味著所有的資訊技術系統和電子元器件都將按照通用技術標準生產,以確保最大化的互操作性。 (北方科技資訊研究所 於洋)

Army Plans Major Stryker Upgrades
(Source: US Army; issued July 30, 2012)
WASHINGTON --- Army engineers are designing and implementing important Stryker vehicles upgrades. The efforts are focused on technologies that will provide the platform a stronger engine, improved suspension, more on-board electrical power and next-generation networking and computing technology.
The Army's more than 4,187 Stryker fleet includes 10 variants of the flat-bottom platform and an additional seven variants of the double V-hull design. The Stryker fleet continues to maintain an overall readiness availability rate of more than 96 percent in Afghanistan and throughout that region, Army officials said.
"We're taking a leap forward to bring this platform to where it will benefit the Army for years to come," said Steven Campbell, Army systems coordinator, Stryker.
Phase 1 of the Stryker ECPs, or Engineering Change Proposal, will lead to a preliminary design review and the construction of a demonstrator vehicle sometime next summer. Phase 1 includes a series of key improvements to the platform designed to, among other things, improve the overall performance of the Stryker, computing and on-board electronics capabilities.
The thrust of Phase 1 includes an electrical power upgrade designed to replace the current Stryker's 570 amp alternator with a more powerful 910 amp alternator and an engine upgrade replacing the existing 350 horsepower engine with a stronger, 450 horsepower engine. The new engine is a commercial-off-the-shelf item.
"We're using a Caterpillar C9 engine, a mature technology already in use. We will package this to fit inside the engine compartment and provide enough cooling for it to operate effectively," said Lt. Col. Jim Schirmer, product manager, Stryker.
The Stryker ECP also includes a stronger suspension that will improve vehicle mobility at higher weights and an in-vehicle network, giving the platform a "digital backbone" able to improve data and video sharing between crew stations in the vehicle, Schirmer said.
The in-vehicle network will include a managed switch, intelligent software, display screens, and processing units, which will allow secure and reliable data-sharing between the systems on-board the vehicle. This will also reduce the size, weight, and power consumption requirements of the future systems integration of the components on the vehicle platform.
"For example, data and video from the driver's thermal viewer, odometer readings, Blue Force Tracker, One-System-Remote Video Terminals and screens which show weapons and targeting-related information will all be shared seamlessly across the various workstations," Schirmer explained. "We have already started some of the early software development for this."
The in-vehicle network approach is grounded in "open architecture," meaning that information technology systems and electronics will all be built to a common set of technical standards ensuring maximum interoperability. This set of standards, referred to as VICTORY, will enable a single computer or system to run a host of interoperable applications and functions. With the VICTORY architecture, the vehicle will be able to streamline and more easily exchange and transmit information while ensuring that the maximum number of programs and applications are possible on any given computer or display screen.
These areas of improvement for the Stryker are now being examined as part of an ongoing cost-benefit analysis slated for completion later this year.
"The Army's cost-benefit analysis will look closely at these four technology areas and determine the best way to get the most efficiency out of the dollars available to improve the platform. We want to make sure that we capture what we need to do, and do so within fiscal reality and other Army priorities," said Norman Stuckey, Army systems coordinator, Stryker.
The Strykers receiving the ECPs will be better equipped to receive a host of new networking gear already being outfitted on vehicle platforms, including Warfighter Information Network - Tactical, a mobile Satcom and radio network and a next-generation force tracking application called Joint Battle Command - Platform, among other things.
