RTCA DO-160: Sanwood Technology's Altitude Test Chambersr Aids in eVTOL Environmental Adaptability Testing

With the rapid advancement of the eVTOL (electric Vertical Take-Off and Landing) industry, airworthiness certification has become a critical barrier to commercialization. Among the certification requirements, environmental adaptability testing of the entire aircraft is a key step. In accordance with authoritative standards such as RTCA DO-160, eVTOL aircraft must withstand extreme environmental conditions including high-altitude low pressure, extreme cold, high temperature, and high humidity. Flight performance and power system stability under these conditions are directly linked to flight safety, and full-process testing must be conducted in large-scale environmental chambers. Sanwood Technology’s Altitude Test Chambers, with their compliance and high-performance capabilities, provide strong support for eVTOL airworthiness certification.

Environmental adaptability testing for eVTOL aircraft must strictly follow internationally recognized standards. RTCA DO-160G Environmental Conditions and Test Procedures for Airborne Equipment specifies detailed parameters and procedures for temperature, humidity, and low-pressure testing, serving as the fundamental guideline for simulating extreme environments. Meanwhile, FAA AC 21.17-3 further defines compliance requirements for whole-aircraft environmental testing. Together, these standards form the core framework for eVTOL certification, highlighting the authority and necessity of such testing.

Walk-in environmental chambers serve as the core equipment for full-scale eVTOL environmental testing. Their testing principle is based on simulating real-world extreme flight conditions: a precise temperature control system combined with humidity regulation replicates high-humidity environments, while a pressure control module recreates high-altitude low-pressure conditions. This enables synchronized simulation of temperature, humidity, and pressure. During testing, the entire eVTOL aircraft operates continuously, with real-time monitoring of key indicators such as power systems, electronic components, and structural stability. Potential failure modes—including power anomalies, component malfunctions, and structural deformation—can be identified in advance, providing accurate data support for performance optimization.

Addressing industry challenges and compliance requirements, Sanwood Technology offers a professional solution with its Altitude Test Chambers:

Temperature range: -70°C to +180°C
