Our Projects

Projects undertaken range from small detailed components to complete aircraft. Remotely operated underwater systems to nuclear de-commissioning equipment. Military and civil aircraft to mass transit rolling stock for clients worldwide.

We have had extensive experience in the structural design & analysis of unmanned concept aircraft from clean sheet through to first flight.

Away from the aerospace sector LEADA Ltd has brought its experience in lightweight and novel structures to be involved with numerous other challenges from waste water treatment plants to train emergency exit doors. Oil recovery hovercraft to rescue submarines.

We look forward to becoming involved with new projects and helping you overcome your design challenges.


AIRSHIPS

AIRSHIPS

LEADA has been involved in several airship projects over the years, for both civilian and military clients. Aspects of the projects have ranged from initial concept design work, to detailed production drawings and finite element modelling of all areas of the airship. The projects worked on have been used in commercial ventures or military applications, including active battlefield situations.

WARBIRDS

WARBIRDS

To keep these wonderful historic aircraft airworthy takes dedication and passion, not forgetting time and money! LEADA has been privileged to be involved in helping keeping some of these iconic warbirds in the air. Whether it has been designing a new replacement part or seeking certification from the CAA for a modern repair to one of the warbirds, LEADA has given the same level of care, commitment and attention to detail as provided to one of its’ more modern aircraft projects.

AUTO GYROS

AUTO GYROS

This type of aircraft is becoming increasingly popular amongst recreational pilots as advances in technology and design make them a safer and more affordable choice over conventional helicopters. For the last 7 years, Rob Littlewood, managing Director of LEADA, has been Chief Technical Officer for Magni Gyro UK Ltd, the UK arm of Italian manufacturer, Magni Gyro SRL, that sells its autogyros globally. Rob is also on the CAA Section T working group for autogyros, helping to create and develop safety and policy documents for this exciting type of aircraft.

All aspects of this project include compilation of compliance checklists, definition and implementation of structural testing, stress analysis, liaising with CAA to gain certification. With LEADA experience and hard work, 2010 was the breakthrough year when Magni Gyro UK Ltd became the first manufacturer of an enclosed twin seat gyroplane to obtain Section T approval from the CAA, with their M24C gyroplane. This now joins the M16C tandem seat gyroplane representing the pinnacle of gyroplane design and safety flying in the UK today.

SURVEILLANCE AND SENSOR AIRCRAFT

SURVEILLANCE AND SENSOR AIRCRAFT

This area of projects has seen LEADA working on several types of aircraft including Diamond Air DA42, Beechcraft King Air , Cessna 172, and an AS355 Eurocopter Twin squirrel helicopter to name a few. Work has involved initial design of equipment structure, for mounting both internally and externally on these aircraft, through the stress analysis, installation and commissioning of the final modification. These projects have also needed close liaison with various regulatory authorities in order to gain the necessary clearances to service, which is all part of remit that LEADA have undertaken on behalf of their clients. When completed, the various aircraft have been used to survey the landscape, provide intelligence gathering for military applications, as well as gathering meteorological and environmental data.

UNMANNED AIRCRAFT

UNMANNED AIRCRAFT

LEADA have been lucky to be involved for many years on numerous unmanned aircraft projects for private clients along with prime global military and civilian aircraft companies.

LEADA have been employed to design, stress and project manage UAV’s ranging from hand launched surveillance drones, small turbojet powered concept demonstration vehicles through to large scale flying demonstration vehicles.

The use of state of the art technology and materials has meant that UAV’s associated with LEADA are now being promoted globally as the latest word in engineering achievement.

AIRCRAFT MODIFICATIONS

AIRCRAFT MODIFICATIONS

When it comes to obtaining modification approvals for either aeroplanes or autogyros, the staff at LEADA have a wealth of experience, having worked closely over many years with various regulatory authorities and UK based Part 21J design approved organisations, to gain such approvals as required by our clients.

So if you want to fit the latest covert surveillance equipment in your aeroplane or just fit a new satellite navigation system in your Magni autogyro, LEADA will be able to help with any design and installation support information required to assist in gaining that much need permit or approval certificate.
