Our Work: Aerospace
PHOENIX – A VARIABLE BUOYANCY AIRSHIP
As part of its novel concept, the Phoenix airship is helium-filled but, unlike conventional aircraft, derives its propulsion from a variable buoyancy system, allowing it to move through the air “like a porpoise through water”.
HELICOPTER NOSE BRACKET BIRD STRIKE
Bird strike can be a significant threat to aircraft and can cause catastrophic structural damage to critical components. Our customer’s equipment and its supporting structure needed to comply with several mechanical strength and safety requirements and, for each of these, they must provide supporting analyses to the aircraft OEM, to demonstrate compliance. These analyses include the dynamic structural modelling of a bird strike to the assembly.
PASSENGER TO FREIGHTER CONVERSION OF AN AIRBUS A321
Our customer is currently modifying an Airbus A321-200 passenger aircraft into a freighter and required support for various aspects of the modification process. The technical complexity of a passenger to freighter conversion is extremely high and is a major modification programme.
Regional Aircraft Design Support
To achieve delivery of the company’s first regional jet aircraft programme, Mitsubishi Aerospace Corporation (MitAC) turned to Stirling for our specialist support. The range of skills required to service the aircraft design were not available within the company or even within the region, so external expertise was required to progress the Mitsubishi Regional Jet (MRJ), latterly known as the Mitsubishi Spacejet.
Airbus Engineering Support
Airbus UK approached Stirling in 2001 to provide external expertise in a range of specialist areas to support their new aircraft design and development projects. As the working relationship grew, the scope of our support increased and after a short period covered all areas of flight physics, landing gear systems, fuel systems and materials and processes across all Airbus aircraft programmes.
Tail Rotor Actuator Design
In support of the Korean Light Utility Helicopter (KLUH) programme, our client, Hanwha Corporation, was faced with the challenge of designing and developing an innovative hydro-mechanical primary flight control actuator that, in addition to providing the design, also transferred knowledge to the client.
Reverse Engineering a Fourth-Generation Jet Fighter
As part of a major update for the Indian Air Force Mirage 2000’s, we were approached to provide the certification clearance analysis that would allow theaircraft to carry non-approved OEM stores on the outboard pylons. The major issue facing us was that certification had to be tackled in the complete absence of OEM aircraft design data.
Bombardier C-Series Independent Loads Review
During the development of their first aircraft with wing-mounted engines, Bombardier Aerospace approached us to provide an independent evaluation of the aircraft design loads. The key attraction was the set of mature tools and processes that we could offer, developed over multiple programmes, to carry out an independent evaluation of the loads.
Landing Gear Design for Amphibious Aircraft
Building on our success as recognised landing gear design consultants, we were approached by a Chinese client that was developing an amphibious firefighting/search & rescue aircraft. The client had issues with the system performance and integration of their complex landing gear system, and we were asked to address this.
WheelTug Taxiing System
The future operation of aircraft will need to meet ever-demanding emission and efficiency targets and therefore innovative solutions are required to support both new and in-service aircraft fleets.
