Our Lightweight Composite Structures Team Deliver

Carbon epoxy gas turbine intake goes into test

Our specialist team of composite structure designers completed the design of a complex executive jet gas turbine intake.
The intake is used for investigating the effects of cross wind on the air presentation to the fan.  This can be a problem especially when the effect of a cross wind running over the fuselage interrupts the air flow being drawn into the intake that is currently under test!


  1. Addressing Real-world Challenges: Designing a gas turbine intake to investigate the effects of crosswind is vital. Crosswinds can significantly impact the performance of aircraft engines, especially during critical phases like take-off and landing. Addressing these challenges head-on can lead to safer and more efficient aircraft operations.
  2. Incorporating Advanced Techniques: The use of particle image velocimetry (PIV) via laser windows demonstrates a cutting-edge approach. PIV is a powerful and sophisticated flow visualization technique that can offer valuable insights into flow dynamics. Understanding potential crosswind effects and mitigating fan flutter is critical for aircraft safety.
  3. Material Selection and Optimization: Choosing an epoxy/carbon lay-up is indicative of prioritizing weight reduction without compromising strength – a fundamental principle in aerospace design. Lightweight structures directly contribute to improved fuel efficiency and overall aircraft performance.
  4. Innovative Integration: Integrating laser windows, which span 50% of the circumference, along with a suite of aerodynamic instruments, showcases an intricate and holistic design approach. This enables comprehensive data collection, ensuring a thorough understanding of the engine’s response to various conditions.
  5. Investment in Future Capabilities: Our team is currently investing in new capabilities and forming partnerships with composite manufacturing specialists suggests a forward-thinking approach. Offering a turn-key service, from design to production, can be a game-changer in the industry, ensuring streamlined processes, reduced lead times, and potentially lower costs.
  6. Potential Impact: With advancements in engine intake design and a clearer understanding of airflow dynamics, aircraft manufacturers and operators can enhance the reliability and efficiency of their systems. This could have positive ramifications for the entire aviation industry in terms of safety, performance, and operational costs.

Thermal Analysis Update

Design Tools

Frewer Engineering’s Advanced Analysis team is involved in some highly specialized and technical work, especially concerning thermal analysis of complex systems. Thermal analysis, particularly with coupled FEA (Finite Element Analysis) and CFD (Computational Fluid Dynamics), is an advanced and intricate task, often vital for ensuring the reliability and efficiency of high-performance systems, especially in industries like aerospace, automotive, and energy.


  1. Coupled Analysis Mode: This approach, which integrates both structural (from FEA) and fluidic (from CFD) phenomena, is crucial when studying systems where the structural behaviour affects fluid flow, and vice versa. This can be seen in applications such as jet engine turbines, where the heat from combustion affects both the metal components and the flow of exhaust gases.
  2. Bespoke Code Creation with Python: As generic tools often have limitations, especially for unique systems, creating custom scripts or modifying the existing solver’s behaviour using Python (or similar) can be essential. This bespoke approach allows for a more tailored analysis that can capture intricate system behaviour’s more accurately.
  3. Thermal Transient Analysis: Analysing the behaviour of systems during transient events, such as start-up, shutdown, or failure, is of paramount importance. These are often the most critical phases for many systems, where the risks of failure or damage are highest. For example, an aerospace component might experience very different thermal stresses during take-off compared to cruising altitude, and it’s vital to understand these differences

Our Gas Turbine Test Facility achieves successful completion of customer review CDR/FDR

Thermal test

Last week we achieved successful completion of the critical design review & final design review of the facility test equipment for the new Whittle Laboratory at Cambridge University.

  1. Historical Significance: The fact that the ground-breaking ceremony for this new facility was one of the first engagements the King attended post-coronation highlights the national and perhaps even international importance of this project.
  2. Innovative Design: Designing a test facility that allows for swift changes of test shapes is an innovative approach. Rapid prototyping and testing in the aerospace industry is essential for staying competitive and meeting the fast-evolving demands of technology, efficiency, and environmental considerations.
  3. Environmental Considerations: With growing global concern about environmental issues, creating technologies that reduce environmental impact is not only beneficial for business but also for the planet. Your project’s focus on this aspect is commendable and very timely.
  4. Potential Impact: Given that the Whittle Laboratory is affiliated with Cambridge University, one of the world’s premier research institutions, the research and breakthroughs that come from this facility could set new standards and influence the aerospace and energy industries worldwide.
  5. Collaborative Efforts: Projects of this scale require collaboration between various stakeholders. The successful completion of the critical and final design review shows the effectiveness of our team and its ability to work together towards a shared vision.

Our team’s efforts in designing a state-of-the-art test facility will undoubtedly play a pivotal role in advancing research in this area. The ability to swiftly test new ideas will expedite innovation, paving the way for more efficient and environmentally friendly propulsion systems in the future.
