BATTLE OF BRITAIN MEMORIAL FLIGHT

CAeS and its predecessors supported the UK’s Battle of Britain Memorial Flight for 40 years.

In that time, we have developed avionics modifications, structural repairs and provided Independent Technical Evaluation of third-party modifications.  We have also provided continual design, airworthiness and safety advice to structures and systems for the Flight’s fleet of Spitfires and Hurricanes.

SAAB 340

CAeS supported the design, development, integration and installation of a wide range of equipment for this unique aircraft modification.

CAeS also delivered the certification process, including flight testing.

Complex Flight Test Instrumentation (FTI) suite measuring all flight control movements, processes the data, and displays it directly to each student

New equipment rack housing data acquisition and management equipment (installed Data Acquisition Computer,
Inertial Measurement Unit, Sideslip Vanes, Navigation System, GPS Splitters)

Cockpit interface in centre pedestal that allows full control of the FTI equipment, battery isolation, master switch, WiFi
switch, etc.

Charging for the students’ tablets via USB or 240V AC.

Camera System for external forward view, cockpit view, and wing view

WiFi System supporting wireless data transmission inside the passenger cabin (including T-PED testing for compliance demonstration)

Installation of a passenger door in the rear bulkhead to make the cargo compartment accessible in flight

Installation of a FLARM Safety System, enhancing situation
awareness for the flight crew

Intercom headset sockets for classroom demonstrators

Certification Basis included Certification Review Items for
“Lithium Battery Installations” (CRI F-04) and “WLAN and Interfacing (T-)PEDs” (CRI F-01)

WEAPONS INTEGRATION

CAeS was contracted by Thales to support the integration of FASGW(L) system and by the MOD to support the integration of legacy Stingray torpedo and depth charge systems onto the Augusta Westland Wildcat helicopters. We also worked alongside MBDA who were supporting the FASGW(H) system and Leonardo helicopters who operated the helicopter.

Defensive Aids Integration

Supporting the integration of defensive aids onto the Chinook Mk5 and Mk6 helicopters and F-35.

Data collection was conducted using bespoke CAeS hardware that was manufactured in collaboration with UK MOD to support flight trials. The hardware consists of an array of data loggers and sensors fitted to a standard Type 118 flare case. This reduces minimal installation effort into standard flare magazines with minimal interference with aircraft systems that  enables faster safety assessments, clearance and turnaround during trials.

Boeing X-48 B/C

11 years of development with NASA, US Airforce and Boeing to design fully representative systems.
CAeS designed and built the X-48 B and C variants in the UK.
Blended wing concept design, considered a contender for future aircraft.
CAeS developed to test aerodynamic characteristics near stall speeds.​
CAeS designed the aircraft systems and ground station for piloting the vehicle.​
CAeS built the flight test demonstrator, support wind tunnel testing.
CAeS supported 7 years of flight testing
The X-48B, is the unmanned X-plane with the most sorties – 130.

Modifications to aircraft.

BAE SYSTEMS

CAeS was contracted by BAE Systems to design and certify various complex modifications on the FAAM BAE 146 Airborne Laboratory under our BCAR A8-21 approval. The aircraft is extensively used for atmospheric research across the world. CAeS modifications include various external apertures for sensors, cameras, and antennas as well as internal modifications for operator consoles, avionics, and supporting structures.

SAFRAN- PROJECT BETA

In 2025, Safran central technologies (Paris) commissioned CAeS to support the development of their own hydrogen
programmes.

Working with the Safran team, CAeS are developing a 50-PAX regional aircraft to design, test and iterate with
new hydrogen powertrain pseudo technologies. With CAeS acting as both pseudo airframer and technology supplier, models with flight analysis provide the teams the opportunity to understand the environmental and
performance challenges associated with the state-of-the-art technology being developed. 

By exploring the integration of complex next generation system technologies through the product life-cycle, CAeS and Safran are able to accelerate early-stage developments, expose aircraft level technology challenges and increase system efficiency.

AIRBUS E-FAN X

CAeS was contracted by Airbus to support the E-Fan X project, a complex hybrid-electric flight demonstrator, which replaces one of the engines with a 2 MW electric motor.

CAeS designed and verified the structure to install and operate the jet engine/electric generator inside the fuselage of the BAe 146 flying testbed.

ROLLS ROYCE

CAeS was contracted by Rolls-Royce to verify the flight safety data under UK CAA E Conditions (CAP1220) for the all-electric “Spirit of Innovation” aircraft, which is the world’s fastest all-electric aircraft. It reached a top speed of 345.5 mph over a 3 kilometres stretch.

CAeS verified all the related documents including risk and safety assessments.
