直接闪电测试程序
Direct lightning strike testing is a crucial part of aircraft design and qualification. Manufacturers must ensure that critical components like flight control surfaces and fuel tanks can withstand the effects of a lightning strike to avoid catastrophic failures.
This is especially true for the newest aircraft designs, where increased dependence on composite materials has made them more vulnerable to lightning strike. As a result, test standards have evolved and become more stringent. To ensure product safety, there are two major types of validation: direct strike and indirect strike testing.
直接雷击测试
As the name suggests, direct lightning strike testing simulates the effects of a direct hit on aircraft or ground-based structures. Using high-powered equipment, we can test exterior materials and interior components to assess for weak areas and ensure continued performance. As the only commercially available provider of direct lightning strike testing in the UK, we provide design support, consulting and testing from start to finish.
飞机雷击测试方法
There are a variety of雷击试验方法available, depending on the type of product being tested and the conditions being simulated. An accredited test lab can help you determine which methods will provide maximum value to your test program.Some of the methods that we offer include:
RTCA DO-160 Section 23 Requirements
高电流测试
我们的设备可以创造一个闪电弧,然后可以在电弧连接位置的物理损伤方面复制雷击到飞机的效果,以及看电流如何通过燃料系统和临界结构元件。
高电压测试
我们的设备允许我们复制雷击的初始领导阶段,该雷击可以应对介电材料,例如天线,放射线和挡风玻璃。乐动娱乐官网
RTCA DO-160第22节要求
我们可以通过RTCA DO-160第22节测试所有波形方法和保护水平。对于具有独特或定制要求的项目,我们具有几乎任何波形瞬态提供的灵活性,为广泛的产品提供覆盖范围。
销注射测试
该方法评估间接飞机雷击效果的最常见的测试方法之一,这种方法将照明瞬变直接应用于电气产品和系统的引脚,以确定它是否会造成任何损坏。
电缆捆绑测试
电缆束测试旨在评估电流屏幕上流流动的电流效果如何效果。有几种类型的电缆束测试:单行程,多冲程和多次突发。单行程方法复制初始返回行程电流对设备上的效果,而多冲程方法在短时间内复制连续闪电附件对飞机的影响。多突发测试的目的是复制领导人这可能会导致冷门装备飞机踏步而去的影响。
静电测试
The increased use of composites in fuels tanks can lead to the accumulation of static. We test aircraft materials to determine if accumulated charge poses a threat to fuel tanks.
ESD测试
我们可以通过处理或由直升机携带来复制充电积累对弹药的影响。
Design Support Services
因为飞机雷击可能会影响飞机上每个系统的完整性,所以在思维中设计具有保护特征至关重要。
航空电子系统的设计和资格过程的一个重要部分是了解瞬态的幅度和类型。我们使用两种方法,通常在一起,帮助设计/资格:计算分析,以预测设备瞬态设计级别(ETDL)和低电流的全车辆测试,以确定实际的瞬态电平(ATL)。
我们的测试服务完全符合RTCA DO-160,MIL-STD-461和DEF STAN 59-411的第22和23个,使USE UK的直接雷击测试的唯一提供者。
