Simulation and Evaluation of High-Voltage Power Systems for Civil Aircraft

Dynamic power quality simulations have been used to asses the performance of the electrical system of a EMA based actuation system for an Airbus A330 size aircraft, for both low voltage 115 V, and high voltage 230 V three-phase AC systems. The high voltage system is shown to have benefits in terms of power quality and reduced size and weight of equipment.

Conversion of 2D data to 3D to Facilitate the use of KBE with Fastened Assemblies

These techniques rely on using three-dimensional CAD data in the form of wing surface models stiffener (stringer) models fastener maps The introduction of a new CNC wing riveting machine necessitated the re-programming of Airbus A320, A321, A330 and A340 wing panel assemblies. Some of these aircraft were designed more than 15 years ago using 2D CAD software, however the latest NC Programming techniques rely on using detailed 3D CAD data.

Electrohydraulic Servovalves in Flight Control and Utility Actuators

This four-hour short course intends to present an overview of electrohydraulic flow control servovalves commonly used in flight control and utility actuators. The scope of this course covers the history and design of servovalves, as well as their most common performance characteristics. This course will provide participants an understanding of the application of electrohydraulic servovalves in hydraulically powered actuators and preparation of the servovalve procurement specification.

First Airbus A330-800 airliner becomes airborne for maiden flight

The first Airbus A330-800 commercial jet, flight test aircraft MSN1888, took off today from Toulouse-Blagnac Airport on its maiden flight over southwestern France during which the aircraft performed dedicated flight-physics tests required for the variant.

Process Development for Use of AERAC

Two Automated Electromagnetic Riveting Assembly Cells (AERAC) were manufactured for Textron Aerostructures by Electroimpact, Inc. The AERAC installs the final rivets in the A330/A340 upper wing panel in the floor assembly jig. At Textron for each wing the corresponding floor assembly jigs for each wing are lined up end to end. An operating procedure in which the formboards are removed in bays allows efficient operation of an in the jig riveter such as the AERAC. Specialized machine codes developed for the AERAC allows quick fully programmed stringer to stringer jumps of the stringer side offset tooling. The AERAC is programmed entirely from a CATIA drawing of the part. Of the 5 axes of rivet data available only two are retained for use by the AERAC.

ELS for the A340

The Electronic Library System is a general designation for Ground and airborne systems in charge of providing Aircraft operators with the information they need. For A330/A340 aircraft, the airborne system is LRU based and the flexibility required by Airlines is provided through a modular configuration. The Airborne Electronic Library System Man-Machine interface is designed to be consistent with the general cockpit design. In particular, the Flight crew display devices are integrated within the sliding tables in front of each pilot station.

Flexible High Speed Riveting Machine

Airbus UK was interested in a high-speed riveting machine cell that could automatically rivet over 30 different wing panels for a wide range of aircraft to fit in a limited floor space. Electroimpact was approached and proposed a Flexible, High Speed, Riveting Machine (HSRM). The resulting flexible riveting cell is 170 feet long and contains two flexible fixtures located end to end. Two fixtures allow manual work on one fixture while the machine is riveting on the second fixture. Each fixture can be quickly reconfigured to accommodate a broad range of Airbus panels. The system went into production on January 12, 2003 and has been extremely effective, riveting the first wing panel, a lower panel 1 for the A330-300 in only 5 days. This was one of the largest panels the cell was sized to accommodate. Anticipated process improvements will reduce the riveting time to just three days per panel.

Automatic Riveting Cell for Commercial Airplane Floor Grid Assembly

With the introduction of the A330/A340 widebody program into the Airbus manufacturing procress during the summer of 1990, it was found necessary to evaluate the situation regarding the production of the Airbus Wide-Body floor grids. Due to the various options or type deviations, the number of different floor structures reached almost 38. To build individual production jigs or fixtures for all of these floor grids would have taken toll on a large amount of factory floor space. The decision was made to establish and build a “Floor Grid Structure Assembly Cell”. This cell mainly comprises of 6 transportable multi-tooling fixtures for the various floor grids in the Airbus Wide-Body sections 13, 14, 16, 17 and 18. A magazine for the storage of the above mentioned fixtures. An overhead crane for fixture transportation in both semi and full automatic modes. Manual manufacturing stations number I and III. Robotic Drill/Riveting Station II. Control Center.

Palletized Air to Air Refueling Kit for Medium and Light Military Transport Aircraft

Air to Air refueling (AAR) operations are typically performed with dedicated tanker A/C. Most existing tankers are derived from civil airliners like the A330MRTT from Airbus Military or from military transport A/C with permanent modifications for the tanker role. For being able to refuel in flight some type of receivers like medium and light turboprops, helicopters and certain UAVs, the tanker aircraft should be able to fly at low speeds. For that role medium/small size turboprop military transport aircraft, like the C295 from Airbus Military are ideally suited. This paper proposes a new palletized AAR kit for conversion of a transport A/C into a tanker. The kit includes all the needed air refueling systems, and can be installed on an existing military transport aircraft with rear cargo door ramp without big permanent modifications to the base platform.

Autonomous Electrical Power System for Multi Role Transport Tanker Aircraft

Today's civil airliners integrate electrical power capability properly sized to supply the growing demands of modern aircraft systems, that are more electrical than ever. The conversion of civil aircraft into a military derivative aircraft faces the challenge of rearranging the available generation capability to feed the new power-hungry military systems while at the same time minimizing the impact on certification of the base aircraft for use on civil operations. This challenge is particularly difficult when the new military systems demand high peak power consumption, as in the case of the conversion of a civil airliner into a military Multi-Role Transport Tanker aircraft with high performance multipoint refueling capabilities. In fact the selection of the type of actuation (either electrical or hydraulic) for the refueling systems is heavily conditioned by the excess of either electrical or hydraulic power available in the base aircraft.

Handling of Large Components for Aircraft Assembly Using an Adaptable Network of Different Kinematic Units

Today's assembly devices used for large-volume components in the aerospace industry are characterized by their inflexibility. This inflexibility is evident by the common use of custom designed rigid structures and specially adapted solutions for a single task. This paper describes an approach for a flexible assembly device, using the example of an aircraft section assembly, capable of integrating and exchanging different kinematic units making it highly adaptable to a variety of assembly tasks and product types. This reconfigurable assembly device uses an integrated measuring system enabling it to handle and assemble different large components with high tolerance requirements.
