Venus Aerospace officially opened a new propulsion test stand at the Houston Spaceport on September 10, 2026, expanding the company’s capacity to test its Rotating Detonation Rocket Engine (RDRE) technology at higher thrust levels and for longer durations.

In a press release, the aerospace company stated the new infrastructure will more closely replicate mission conditions as it scales integrated propulsion systems for defense and space applications. The facility’s opening follows a $91 million Series B financing round closed in July 2026 to accelerate RDRE production.

Scaling RDRE technology

The RDRE architecture utilizes a continuous supersonic detonation wave rotating around a combustion chamber. According to Venus Aerospace, this design is 15 percent more efficient than conventional subsonic combustion rocket engines. The company previously completed the first United States flight test of a high-thrust rotating detonation rocket engine at Spaceport America in New Mexico on May 14, 2025.

To transition the propulsion system from flight demonstration to deployment, the company required expanded physical infrastructure capable of handling sustained engine runs.

“Building and testing propulsion systems at this pace requires the right infrastructure around the technology,” said Sassie Duggleby, CEO and co-founder of Venus Aerospace.

Public and private investment

The expansion at the Houston Spaceport is supported by both private capital and state-level investment. In July 2026, Venus Aerospace secured $91 million in Series B funding led by Mercury Fund, with participation from Lockheed Martin Ventures and other investors. The capital is specifically earmarked for maturing the flight-proven RDRE into full propulsion systems.

The company also highlighted the role of local and state authorities, including the Texas Space Commission and the Houston Airport System, in facilitating the new test stand.

“We’re grateful to the Texas Space Commission and the State of Texas for investing alongside companies like Venus. Public investment like this helps companies move faster and keeps critical aerospace capability growing here in Texas,” Duggleby stated.

AirPro News analysis

We view the opening of the Houston Spaceport test stand as a critical bottleneck cleared for Venus Aerospace. While the May 2025 flight test proved the fundamental viability of the high-thrust RDRE concept, scaling the technology for defense and commercial space applications requires rigorous, long-duration ground testing. By securing both the $91 million in private equity and the physical footprint to run continuous high-thrust tests, the company is positioning itself to transition from a research and development firm into a primary propulsion supplier. The 15 percent efficiency gain over conventional rocket engines makes the RDRE highly attractive for next-generation defense platforms and launch vehicles, provided the manufacturing and integration challenges can be met.

NOEMI Aerospace has selected advanced materials manufacturer Syensqo to supply carbon fiber composites and structural adhesives for its nine-passenger all-electric amphibious aircraft.

The agreement, announced in a September 10, 2026, press release, secures out-of-autoclave materials critical for fabricating the aircraft’s 21-meter single-span wing structure. The selected materials feature existing National Center for Advanced Materials Performance (NCAMP) data, which NOEMI intends to leverage for its Federal Aviation Administration (FAA) certification program.

Composite materials for single-span wing construction

Syensqo will provide its MTM® 45-1 carbon fiber prepreg and AeroPaste® structural paste adhesive for the airframe and wing assembly. NOEMI Aerospace requires out-of-autoclave curing capabilities to accommodate the physical dimensions of the aircraft’s wing skins and spars, which the company plans to manufacture as a continuous 21-meter structure.

Simon Bendrey, Chief Engineer at NOEMI Aerospace, stated that the company needed a primary structure-capable material with proven performance to support this manufacturing approach.

“With Syensqo’s MTM® 45-1, a primary structure capable material with FAA approval and independently verified NCAMP data, we have a solution that will support our certification approach while helping us achieve the low structural weight required for our first prototype aircraft,” Bendrey said.

Bendrey added that the company will utilize the AeroPaste® structural adhesive to bond the wing components. Gerald Perrin, EMEA Sales Director for Syensqo Composite Materials, noted that the selection reflects the aerospace heritage of the company’s product line and its alignment with Electric-Aviation development.

TAC-1 prototype and multi-mission development

The materials partnership advances the construction of NOEMI’s TAC-1 experimental prototype. Following a preliminary design review completed in March 2026, the Norwegian Manufacturers is currently building a ground test rig. According to reporting by Aviation International News, the company expects to run a propeller on the test rig by the end of the third quarter of 2026.

The all-electric seaplane is designed for a range of approximately 200 kilometers, targeting short-haul routes between coastal islands and waterway-connected communities. While initially focused on passenger transport, NOEMI Aerospace, which rebranded from Elfly Group in February 2026, announced a multi-mission Strategy on May 19, 2026. The company plans to adapt the airframe for specialized operations, including aerial firefighting, medical evacuation, troop transport, and skydiving.

We view NOEMI’s selection of an out-of-autoclave composite system with existing NCAMP data as a pragmatic risk-reduction strategy. Electric aircraft developers face strict weight limitations due to current battery energy densities, making lightweight composite structures mandatory rather than optional. By choosing a material that already possesses verified performance data and FAA familiarity, NOEMI can avoid the time and expense of a clean-sheet material qualification program. The ability to cure a 21-meter wing structure outside of a traditional autoclave removes a significant Manufacturing bottleneck and reduces capital equipment costs for early-stage prototype production.

On September 10, 2026, America’s Consortium for Electric Skyways (ACES) announced plans to deploy an interoperable electric aviation charging network across Texas to support the state’s upcoming air taxi operations. The infrastructure rollout targets the “Texas Triangle” and surrounding rural areas, providing a critical physical foundation for the White House’s electric vertical takeoff and landing (eVTOL) Integration Pilot Program (eIPP).

In a press release issued by Archer Aviation Inc., the consortium, a joint initiative launched by Archer, BETA Technologies, and Macquarie Capital, detailed its collaboration with the Texas Department of Transportation (TxDOT). The shared infrastructure model is designed to prevent the fragmentation of charging systems by allowing multiple operators to utilize the same chargers as commercial eVTOL flights begin.

Targeting the Texas Triangle

The U.S. Department of Transportation (DOT) and the Federal Aviation Administration (FAA) selected TxDOT’s eIPP proposal in March 2026. The federal program aims to safely integrate electric aircraft into U.S. airspace by allowing early commercial operations to proceed, which will generate operational data to inform future regulations.

ACES will work with TxDOT over the coming months to identify optimal locations for charging infrastructure based on where aircraft operators plan to fly. The initial focus centers on the Dallas/Fort Worth, Austin, San Antonio, and Houston metropolitan areas, alongside connecting rural communities. Sergio Roman, Emerging Aviation Tech Director at TxDOT, stated that building the charging infrastructure puts Texas at the center of the next generation of aviation while improving safety and connectivity across the state.

Interoperability and Industry Expansion

The consortium’s broader goal extends beyond the Texas borders. ACES aims to electrify 250 air taxi sites across major American airports and metropolitan areas over the next decade. By utilizing an open standard, the consortium intends to support the entire industry rather than a single manufacturer’s proprietary technology.

Archer Aviation Founder and CEO Adam Goldstein emphasized this approach, noting that interoperable chargers built on an open standard are how the push for commercialization becomes real. BETA Technologies Founder and CEO Kyle Clark echoed the necessity of shared resources for the emerging sector.

“Aircraft are only useful if you have the infrastructure in place to support them. ACES is about making sure that infrastructure is interoperable, reliable, and ready where operators need it,” Clark said.

Concurrent Flight Testing Operations

The infrastructure announcement coincides with active flight testing in the region. On September 10, 2026, Joby Aviation, Inc. officially commenced its own White House-backed eIPP flights in Texas under TxDOT’s Project Nexus. Joby’s week-long flight campaign across the Dallas-Fort Worth region highlights the immediate need for the charging networks ACES is planning to build.

Archer Aviation also launched its ‘No Roads’ flight tour in early September 2026 to expand the city-to-city flight test program for its Midnight aircraft, setting the stage for increased hardware demands at regional airports and vertiports.

AirPro News analysis

We view the ACES interoperability strategy as a necessary step to avoid the proprietary charging bottlenecks that initially plagued the automotive electric vehicle market. By standardizing the infrastructure early in the eIPP process, operators can share capital expenditures and real estate at constrained vertiport locations. The concurrent launch of Joby Aviation flight tests and the ACES infrastructure plan in Texas demonstrates that the eIPP is rapidly moving from a policy framework into physical operations. If ACES can successfully deploy its open-standard network across the Texas Triangle, it will likely serve as the blueprint for the consortium’s planned 250-site national rollout.
