The Landing Systems Engineering Group (LASEG) is a collection of academics from across Cranfield University with the common goal of addressing the identified knowledge gaps that prevent the development of landing gear technologies and landing system concepts. Landing gear and associated systems are yet to see a fundamental technological revolution since the 1950’s despite other parts of aircraft benefiting from significant disruption from the introduction of new materials or technologies.
The take-off and landing of an aircraft are critical and complex processes involving several systems, such as landing gear, airport infrastructure, and air traffic management. So, the words ‘landing systems engineering’ (LSE) refer not only to the engineering concepts found in the physical landing gear but the whole framework of complex systems surrounding this part of the aircraft and its operation. Although it may not be obviously apparent, landing systems will play a role in reducing aviation’s environmental impacts. A lighter, more aerodynamic, higher performing landing gear will have a positive impact on whole aircraft design and operation. This will not only improve the fuel efficiency of aircraft but significantly reduce noise nuisance in airport catchment areas.
LASEG was founded in 2008 and is mostly engaged with user-inspired research in close collaboration with Airbus. Funding of more than £11M has been secured from various sources (IUK-ATI, Airbus, EPSRC, NERC, RAEng). The approach of LASEG has been to transform the empirical-based landing gear into a digital model-based product to develop new design criteria and enable a systems-of-systems approach that provides opportunities for optimisation and adoption of new materials and technologies. The models enable optimised integration with airframe and wings as well as manufacturing and assembly processes. In addition, the numerical models support new approaches in prognostics and health management through digital twin development supported by artificial intelligence, leading to cost-effective maintenance.
A report (Airbus Global Market Forecast 2025-2044) estimates that over the next 20 years, 43,420 aircraft will be delivered across the world. When considering that under 22,800 aircraft were in operation in the beginning of 2020, it gives an indication of the scale of future demand for aircraft. Landing systems are multifaceted and interdisciplinary, covering a wide range of research disciplines, ranging from molecular dynamics to system-level optimisation and control. Hence, interdisciplinary academic–industry collaboration is vital when conducting disruptive research into LSE. Traditionally, end-to-end sustainability and enhanced safety have been the main constraints. Now, new powertrain, airframe architectures and fuel systems provide opportunities for novel design of integrated landing systems.
