Aviation Enterprises Ltd

Aviation Enterprises Ltd is an established aviation based design, development and manufacturing engineering company specialising in composite materials with special experience in sub-sea structures and fatigue. AEL offers a unique one-stop seamless service from customer concept through structural design/prototyping/testing/tooling/manufacture and certification, currently specialising in tidal turbine blades, wind turbines and other marine renewable energy projects.

Design & Engineeirng

Aviation Enterprises Ltd is an engineering company specialising in the design and manufacture of lightweight, high performance structures, in particular using carbon fibre and glass fibre composites. Engineering is at our heart. We thrive on variety (see some of the Projects that we have brought to fruition) - indeed we often apply our experience & principles found in one sector to problems in another and welcome challenges from other sectors.

Our design team has a track record of successful innovative solutions, weight saving projects and new materials technology; and specialising in the the use of composite materials provides corrosion resistance, low maintenance, and significant weight savings as well as very good fatigue performance.

The Magnum aircraft shown was entirely designed and manufactured and tested in house at AEL.

Design & Engineeirng


Aviation Enterprises Ltd has, since 2002 been developing a wealth of experience in design and manufacture of Tidal Turbine (TT) blades. As a result of this momentum, and interest expressed in our capabilities by other UK tidal turbine developers, AEL decided, in 2005, to apply its expertise and develop this business to provide a specialist composite TT blade design, development and manufacture service, focussing R&D on reliable design, efficient use of materials and minimising development and production costs. In particular by; 

  • Effective materials selection and establishment of a comprehensive materials database. Manufacturers’ data is rarely considered definitive and necessitates independent testing.
  • Research into the effects of long-term immersion in seawater, something that is a relatively new requirement.
  • The review of adhesives and surface preparation techniques. Again, reference material for previous work is unlikely to be available.
  • Investigating and meeting the standards and safety factors applied by the Certification Authorities.
  • Investment in our own suite of numerical tools and production and tooling equipment to minimise costs.

Engineering Experience

Concept feasibility and preliminary design work; We can cast an objective eye over your concept and advise on the best way forward. For more complex problems, we can also conduct a preliminary study in order to properly assess the suitability of a number of different design solutions. Our advice is underpinned by a high degree of technical competence, general engineering knowledge and practical experience, and we always relish a challenge.

Design for prototyping and production; Having established the most suitable route to success, we have the tools, knowledge and contacts to complete the detailed design of your project.
Engineering analysis capabilities :
Loads Analysis
Stress analysis and static strength prediction (including composites)

Fatigue analysis and life prediction - a speciality.
Natural frequency and stiffness analysis
Finite Element Analysis (including composites ply by ply)
We can also arrange CFD based aerodynamic or hydrodynamic optimisation.

The mechanical design, early manufacture and test for the QR5 VA wind turbine was carried out at AEL

Engineering Experience

Light Aviation Design

2003 The Magnum VLA project was internally funded and taken through to and including the test flight phase. This aircraft is still one of the most fuel efficient in the world with a cruise speed of 155 kts on 100 hp , range of 2000 nm and fuel consumption better than 50 mpg

This aircraft also incorporated possibly the first all composite retracting undercarriage. 

Marine Composites Design

2001 The JAMAR project, carried out for a private client to build the drive chain, including carbon fibre rotor, drive chain and water screw for a wind rotor driven catamaran was highly successful and we predict will eventually prove useful for commercial shipping.
