01 / HOW WE HELP

What are you ready
to develop or resolve?

Bring us a new hardware concept, a material challenge, or a program that needs specialist support. Start with a focused review or scope a broader development and evaluation effort.

Connected disciplines.
Better-informed decisions.

Requirements guide the work. Findings feed back into material and design choices.

Application requirements connect materials, components, integrated systems, and verification in a loop. Verification findings inform the next material and design choices.
01EMI/EMC & ELECTRONICS

Control interference.
Strengthen your design.

Design electromagnetic compatibility into new hardware or investigate a test finding. We help work through coupling, grounding, shielding, and integration choices before defining how to verify them.

  • Architecture, grounding, bonding, and shielding reviews
  • Filtering, coupling paths, and signal integrity
  • Test findings and corrective-action planning
TYPICAL DELIVERABLES

Prioritized findings, mitigation options, and a verification plan.

What we would review
Available schematics, interface and harness information, operating modes, requirements, and test reports. We agree on the investigation scope and required specialist support before work begins.
Discuss an EMI/EMC issue
02MATERIALS & PROTECTION

Develop the right
material approach.

Balance protection, weight, electrical behavior, and processing needs. We help evaluate existing materials and scope application-led development when the available choices leave a gap.

  • Coatings, adhesives, sealants, and potting
  • Shielding and thermal-protection approaches
  • Substrate compatibility, coupons, and process trials
TYPICAL DELIVERABLES

Candidate comparisons, application considerations, and an evaluation plan; coupon or process trials can be included in the scope.

What we would review
Your operating environment, substrates, material data, manufacturing constraints, and acceptance criteria. Development work is scoped around the properties and process conditions the application actually requires.
Discuss a materials challenge
03TEST & QUALIFICATION

Build a path
to qualification.

Plan verification early, prepare for an upcoming test, or work through the findings. Connect requirements to the evidence your hardware needs and make each test responsibility clear.

  • Requirements and verification planning
  • Readiness reviews and test coordination
  • Results interpretation and issue resolution
TYPICAL DELIVERABLES

A requirements-to-test matrix, readiness gaps, and defined test responsibilities.

What we would review
Applicable requirements, hardware configuration, existing evidence, and the test schedule. Specialized facility testing is coordinated with appropriate external laboratories; responsibilities and acceptance criteria are identified in the scope.
Discuss a qualification milestone
04SYSTEMS & INTEGRATION

Connect materials,
electronics, and systems.

Developing capable hardware means getting the interfaces right. We help connect architecture, packaging, thermal considerations, electronics, and embedded systems around your requirements.

  • Architecture and interface reviews
  • Ruggedization, packaging, and thermal integration
  • Embedded systems and lifecycle considerations
TYPICAL DELIVERABLES

Documented design tradeoffs, interface findings, and an integration or prototype-development plan.

What we would review
System requirements, interfaces, operating modes, packaging constraints, and known issues. We identify the disciplines needed for the assignment and the work that can be completed within the agreed scope.
Discuss an integration problem

02 / WORK & TECHNICAL EVIDENCE

A closer look
at the work.

Useful materials begin with an understanding of how processing shapes performance. Explore our internal research and an example of how we structure a customer evaluation.

DELTAX INTERNAL RESEARCH

Understanding how processing
affects gel integrity.

Our internal materials research examines how preparation, curing, and drying affect polymer-gel formation and integrity. Experimental records track shrinkage, cracking, and handling behavior to guide the next questions.

THE QUESTION

How do preparation and drying choices affect the resulting specimen?

THE WORK

Record process history and the visible condition of samples across experimental runs.

THE VALUE

A basis for investigating failure modes and defining what the next experiment should examine.

Current stage: precursor-material process studies. Functional performance remains to be established through testing.

03 / RESEARCH & VISION

The next material.
The next mission.

New aerospace possibilities begin at the material level.

Our ambition is to develop advanced materials, protective systems, and aerospace hardware—and ultimately new ways to propel small spacecraft.

That means investigating how materials are made, how they behave, and how they can be integrated into a useful system. Research collaborations start with a defined technical question and milestones that make progress measurable.

ADVANCED MATERIALS RESEARCH

More function. Less mass.

Exploring carbon-based materials, aerogels, and nanocomposites with the goal of combining low mass with useful thermal, electrical, or structural behavior.

AEROSPACE DEVELOPMENT DIRECTION

From a material to working hardware.

Developing toward protective coatings, components, and subsystems that connect materials innovation with the requirements of an aerospace application.

LONG-TERM PROPULSION RESEARCH

Precision mobility for small spacecraft.

Investigating carbon-nanotube and aerogel electrospray concepts, ionic-liquid propulsion, and emitter architectures for future spacecraft maneuvering.

These research areas are under development. Performance and readiness require application-specific testing; propulsion concepts are not flight-qualified product offerings.
