As the aviation industry advances its sustainability ambitions, developers of electric, hybrid, and hydrogen-powered aircraft face challenges in matching the range, payload, and performance of traditional gas-powered designs.

To address this issue and enhance the competitiveness of "green" aircraft, TT Electronics is introducing a suite of high-voltage DC power conversion solutions. The UK-based company asserts that these solutions will improve performance by enabling more efficient, longer-duration flights at higher altitudes compared to current off-the-shelf components. TT Electronics announced this high-voltage DC power conversion solution on Tuesday at the Farnborough International Airshow.

“What we're seeing in terms of the urban air mobility market and even the civil and military aviation markets now is that our customers are after almost modified off-the-shelf products,” Kevin Littler, head of business development at TT Electronics, told AIN. “They want something that's quick and they don't want to pay a lot of non-recurring engineering costs for it, but they still want it to be suitable for their requirements."

“So, we are developing effectively a set of modular building blocks that can then be used to quickly develop those specific power supplies for our customers.”

While the technology is suited for urban air mobility vehicles such as eVTOL air taxis, Littler noted that AltitudeDC aims to meet the needs of the civil aviation market. “Civil airliners will require high-voltage DC power conversion and military aircraft are going down that path too,” he said.

With the push to electrify aircraft, relying on AC power is not feasible due to cable weight and size concerns. Littler explained that similar issues were encountered during the electrification of the automotive industry as more electric ground vehicles entered the market.

TT Electronics is collaborating with the UK’s Aerospace Technology Institute along with other industry and academic partners to develop the AltitudeDC portfolio.

Separately, last week TT Electronics announced an expansion of its partnership with Parker Meggitt. The multi-million dollar agreement aims to develop complex electronic assemblies for commercial aircraft braking systems.
