MKH Business Limited provides Marketing Support to AAI Aerospace (the aerospace operating division of the AAI Group). Their principal activities include the design, development and production of innovative test solutions for their prestigious clients in the civil, military and R&D Aerospace for both Composite and Metallic Aerostructures Structures for Production applications and for Maintenance Repair & Overhaul (MRO) applications – For fixed wing and rotary wing applications. AAI Aerospace's Productivity and Quality Enhancing Equipment/Test Solutions also have many applications in other non Aerospace/Aviation Structures.

Products include:-

 

Thru skin sensor technology DAS - Drill Alignment System - Hole Finder/"Blind" Hole Spotter

Suitable for use with both Composite and Metallic Structures, for Production applications and for Maintenance Repair & Overhaul (MRO) applications, where production, repairs and/or modifications lead to a requirement to locate and align with existing holes in structure beneath the component being drilled through. One of the most time consuming activities in aerostructure manufacture and repair is the location of buried fastener holes and the subsequent alignment and drilling of the corresponding hole in the aircraft skin. The AAI Aerospace hole finder is the most accurate, smallest and lightest product on the market to fulfill this function.

This equipment can be supplied with a range of accessories that include a unique and highly efficient Vortex Dust Extraction Plate,that removes dust and swarf from close to the work surface and channels it away from the work area. The Vortex Dust Extraction Plate is particularly useful when drilling through Carbon Structures. Bespoke accessories can also be developed, if required, for specific applications. There is now already also a Heavy Duty Vacuum Mounting System option available.

The thru skin sensor technology DAS - Drill Alignment System - Hole Finder/"Blind" Hole Spotter has been supplied to Airbus for use in aircraft Wing Production and it has been approved by EADS.

The MT9000 portable multifunctional Online Resistance Test System

The MT9000 is a portable battery operated multifunctional test unit, it is used to perform Bond and Loop Resistance Testing during the production, conversion, Maintenance Repair & Overhaul (MRO) of Aerostructures Assemblies (for example it is used by Airbus on all of their Civilian wing production programmes and on their A400M Military Airlifter programme) to ensure electrical conductivity of Aerostructures (e.g. when testing to ensure a path for dissipation of energy from lightning strikes). To see an Airbus A380 being struck by lightening and understand the benefits of testing with suitable equipment such as the MT9000, click here.

The MT9000 is also used to test aircraft wiring harnesses including: resistance testing of resistive limits on Screen to Body Connections and other such testing of Cable Shields and Shield Connections in aircraft wiring bundles (both during Production and during subsequent MRO Activities).

The AAI Aerospace Product offers a highly accurate, customisable, solution that can be used for a multitude of applications. It is a very effective Loop Resistance Tester, likely to be much in demand as the Aerospace Industry and Airline Industry begin to realise the benefits of carrying out an accurate, specification defined, Loop Resistance Test on Cables/Wiring Harnesses to measure Shield Path resistance when the Cables/Wiring Harnesses are initially manufactured and during subsequent Maintenance Repair and Overhaul (MRO) activities. The AAI Aerospace Loop Resistance Tester can also be used to assist Maintenance personnel to detect corrosion/loose hardware within the aircraft's electrical circuits.

The MT9000 uses the latest Li-ion smart battery technology and it is capable of automatically measuring metal to metal bond resistances using a traditional 4-wire Kelvin technique. The unit when connected to a central data-base, using a wireless or wired network, allows the MT9000 to download test specifications and drawings and upload test results. This provides an authenticated auditable data trail and a subsequent reduction in test times by a factor of 6. The MT9000 can measure bond resistance, loop resistance, antistatic coating resistance and can operate in a standalone multimeter mode capable of detecting loop faults, general measurements of resistance and AC and DC voltage measurement. The MT9000 allows the operator to log on to a database which means that the operator no longer has to manually input and verify the test results, thus saving time and eliminating errors. It is not possible to make readings with a unit that is out of calibration, and authenticated measurements cannot be made by an untrained user.

The MT-9000’s Measurement Technology system allows semi skilled personnel to make complex and highly accurate measurements, with a secure and auditable data recording capability. The type and nature of the tests to be carried out and the required pass-fail criteria are automatically downloaded from a secure server via a radio link. On completion of a successful test the results are automatically uploaded to the server thus providing a truly paperless and secure system. In production environments, this authenticated auditable data trail gives a typical reduction in test times of 80%. The unit is capable of a number of different measurements. At present it is used to measure, contact resistance measurement with a maximum range of 0-2 Ohms with a maximum resolution of 0.000001 Ohm i.e. 1 millionth of an Ohm, and non-contact loop resistance measurement to the same specification. The system guarantees adherence to quality and safety standards in a highly regulated, safety critical manufacturing and/or MRO environment.

The unit has been designed in a modular format so it is possible to change the measurement interface to make any type of physical or electrical measurement.

The MT9000 can be supplied with a number of different probe types. The standard bond probe includes pass-fail indication, LED illumination for use in dimly lit areas and rugged peizo test acceptance switch. AAI Aerospace can manufacture Probes to suit customers specific requirements - Previous requests have included long Probes (to reach particularly awkward locations). Loop probes are manufactured using Chevin Arnoux current clamps; several different diameters are available. The MT9000 can also be supplied with a hands free clamp to attach to any metal surface allowing for single user operation in difficult areas. The antistatic resistance probes are fitted with 2” conductive rubber pads with a contact resistance of less than 2 Ohm which means that only light pressure needs to be applied, eliminating the possibility of damaging the coating. Again the active probe has pass-fail indication and a test acceptance switch.

MM10 - Rivet Depth Gauge

 

The MM10 which ensures that fasteners are placed at the proper depth in the work piece. It can be used in Production and/or in Maintenance Repair & Overhaul (MRO) applications. The MM10 records the fastener head deviation from the aerostructure skin surface and performs statistical and mathematical calculations on the resulting data. The information is used to adjust the settings on riveting equipment and can be downloaded for quality assurance purposes. To ensure a quality joint, it is important that the fastener be placed at the proper depth in the workpiece. If the countersink is too deep, the rivet joint ultimately created could be weakened and subject to corrosion. If the countersink is too shallow, the head can create aerodynamic drag.
