im体育APP闪电科技 卓越中心

im体育APP闪电科技 in 皮茨菲尔德, 麻萨诸塞州 houses one of the most complete lightning-simulation laboratories in the world and ranks as an international leader in the development of sophisticated lightning protection 系统 for customers in the aerospace industry as well as for industrial complexes, 高尔夫球场, 风力发电厂, 主题公园和其他高风险地点. Our operation includes both 14-foot and 25-foot tall generators.

Design protection for all kinds of 飞机 & 其他应用程序

We provide design services for all kinds of 飞机 Including fixed wing, helicopters and eVTOL as well as wind turbines, ships employing carbon fiber and any facility that can experience damage from lightning strikes. We have long standing experience with compliance with applicable airworthiness regulations and test standards published by 美国联邦航空局, 负责, RTCA, and the IEC standards applicable to wind turbines. We also know how to design for compliance with the IEC and NFPA standards for ground-based facilities.

im体育APP闪电科技 has provided lightning protection design and validation for major 飞机 and space vehicles and launch facilities including NASA Space Shuttle and KSC launch complexes. 其他客户包括:GE, 美国联邦航空局, 汉胜, 美国宇航局肯尼迪航天中心, 华特迪士尼世界的未来世界中心, 台风泻湖, 和动物王国公园.

Analysis and 测试 of 系统s and Sub系统 to Determine Optimum Protection

im体育APP闪电科技 engineers and technicians are recognized experts in the field of lightning protection. The electrical characteristics of the different types of lightning flashes, and the resulting surges and fields from a strike, 是复杂的.

Engineers have found that to study the effects of lightning upon a structure or system, it is most efficient to isolate the components of the lightning waveforms and electrical/magnetic fields and to evaluate their effects through individual simulations. Our lab includes specialized and unique equipment to simulate all the electrical characteristics of natural lightning as well as the transients it induces in electrical and electronic 系统.

从航空电子设备到军事装备, our lightning testing gives manufacturers the data they need to produce robust components and 系统 designed to remain operational even when surges resulting from lightning strikes occur.

直接仿真与建模 & 闪电的间接影响

模拟 and 建模 of structures and 系统, to complement our testing capabilities. 我们使用COMSOL多物理场平台. This is useful when we are assisting with designs of protection for as-yet unbuilt structures or equipment. We have the advantage that we have everyday familiarity with how lightning currents behave throughout airframes and other structures, and so can validate our models (and know when modeling is not needed).

Our finite element analysis capabilities allow us to perform complex simulations to accurately model the interaction of lightning with a variety of 飞机 和航空电子设备 components for our customers. By decomposing complex CAD-generated objects into meshable geometrical shapes, we are able to accurately portray the lightning environment on high fidelity renditions of real objects.

多次冲程和多次爆发

The flickering seen in a lightning strike to the ground actually is caused by a series of current strokes, the electrical characteristics of which are called multiple stroke. 另一方面, inter- and intracloud lightning has very different electrical characteristics, referred to as multiple stroke and multiple burst, and require that aerospace electronic 系统 that perform critical or essential functions be tested against the effects of both types of lightning. We have the most versatile facility for both multiple stroke and multiple burst testing.

静电

We perform many types of static electricity tests. These procedures simulate the range of static effects: from those occurring on 飞机 that can exceed 100,000伏到
small, 但是有潜在危险的电压, produced by manufacturing and material handling operations.

研究与发展

我们的能力包括R&D for designs of new lightning protection methods and products for advanced air vehicles, 系统, 设备及材料. We have collaborated with several small businesses in seeking funding and support for US Government Small Business Innovation Research (SBIR) grants through Phase II and beyond. We look forward to working with you to achieve similar success.

Direct Effects Lightning 测试 at im体育APP闪电科技

Lightning Physical (Direct Effects) Test to determine the effects of lightning on a wide variety of materials, structures and fuel 系统 can be conducted in our high voltage (HV) and high current (HC) laboratories in 皮茨菲尔德, 麻萨诸塞州. These are conducted in accordance with the SAE ARP 6514和EUROCAE ED 105 standards and are applied for protection design and development as well as certification.

The direct effects of lightning include the physical damage due to the attachment of the very hot (20,000°C)和高电流(250,000+安培)闪电通道. These effects include the burning and shattering of materials and the direct conduction of lightning voltages into electrical and electronic circuits resulting in burnouts of equipment.

Two basic types of generators are used for direct effects testing: High voltage, Marx-type impulse generators produce voltages and electric fields up to 2.4 million volts to simulate lightning leader attachment and surges induced on power transmission lines. The high current generators produce up to 250,000 amperes and include three units adapted to duplicate the lightning stroke, and intermediate and continuing current waveforms of a typical lightning strike.

以容纳非常大的测试样本, direct effects tests are performed in facilities like Lightning Technologies’ indoor high-bay laboratory that measures 80 x 100 feet.

间接影响雷电试验

Lightning and Transient (Indirect Effects) Tests of Electronic 系统s and Equipment for 飞机 and other 系统 performing critical functions. We conduct these tests at im体育APP闪电科技 in 皮茨菲尔德, 麻萨诸塞州 as well as at our customers’ facilities around the world, since it is sometimes more efficient for us to transport our test equipment, 哪个是为旅行配置的, than to transport customer 系统 to our laboratory. We conduct these tests at all of the standard waveforms and transient levels. We can apply both the individual transient tests to equipment and the Multiple Stroke/Multiple Burst1 waveform sets to 系统 or sub系统. Whereas other testing companies also perform these tests, we bring knowledge of the physics of indirect effects mechanisms, 测试方法的起源, 以及防护设计方法. We offer test planning services that help our customers apply the correct tests and often avoid unnecessary testing, 或失败. We have many years of experience with real-world lightning strike experience of 飞机 and ground-based 系统. 

The indirect effects of lightning are caused primarily by earth-voltage rises that occur when the flash dumps charge into the earth and by the intense electromagnetic field associated with the flash. These fields and earth-voltage rises have enough energy to cause component damage up to a kilometer or more from the actual strike.

Indirect effects are most commonly induced into system interconnecting cables and may damage or upset electronic components. im体育APP闪电科技 has been at the forefront of indirect effects test method development for many years. 这些方法在IEEE中有定义, ANSI, SAE, EUROCAE, US MIL-STDs and many industry and company standards and specifications.

The indirect effects testing lab includes many specialized devices for complete field and transient analysis, from the level of individual circuits to completely operational interconnected 系统. Typical indirect effects tests include pin injection, 变压器注入, 电容式注射, ground-circuit injection and field immersion techniques.
