MUSKETEER CASE STUDY
ENGINEERING DATA SERVICES PROVIDED TO THE BATTLE OF BRITAIN MEMORIAL FLIGHT – MODULAR SIGNAL RECORDERS & PARAMETRIC DATA GATHERING SYSTEM
Musketeer has been supporting the Battle of Britain Memorial Flight (BBMF) for many years providing specialist engineering services to capture and analyse the use of these historic aircraft which includes Spitfires, Hurricanes, a Dakota and Lancaster.
It is important to know how each aircraft in the BBMF fleet is being operated on every flight and so Musketeer provides Modular Signal Recorders, which are small (70 mm x 40 mm) battery-powered devices that record the altitude of aircraft and how many ‘g’ (normal acceleration) the aircraft is experiencing during every flight.
Musketeer analyses the data downloaded from the MSRs for every BBMF sortie and provides reports to the BBMF Project Team about the flying carried out on their public displays performed around the country. This information is vital to ensure that BBMF aircraft are being maintained in accordance with their approved schedules. An extract from a typical BBMF flight profile is shown below
Modular Signal Recorders (fitted to all BBMF aircraft)
Example Raw Data Output from Modular Signal Recorders
Some of the BBMF aircraft are fitted with a more sophisticated flight monitoring system known as the Parametric Data Gathering System (PDGS). This multi-channel system has a wide variety of sensors and a data logger which can be interrogated to check, for example, engine coolant temperature or hydraulic system pressure at any stage of the flight.
The PDGS is a derivative of the Pi Cosworth system fitted to Formula One racing cars and, as its software controlled, each channel can be programmed separately to capture the data every second or even every one hundredth of a second! After a flight, the data is downloaded from the logger mounted inside the aircraft fuselage and the results are displayed on a laptop
Musketeer analyses and stores the PDGS data on behalf of the BBMF to ensure that aircraft systems are carefully monitored for any adverse trends in performance, so that preventive maintenance can be carried out, if required.
Our data monitoring and analysis services are not restricted just to aircraft. Musketeer has also carried out many other trials for customers to measure, for example, humidity levels in buildings where it is important that equipment is stored in the right dry conditions to prevent deterioration due to corrosion.
One such field trial, also using Modular Signal Recorders (MSRs), was to measure changes in humidity inside a large temporary shelter, designed for aircraft operations. The shelter was subject to dehumidification and the MSRs recorded the differences between the external and internal relative humidity (RH) levels. An example of the raw results is shown in the graphs.
