Aviation

For several years BAUER Engineering has developed also for the aviation industry. Highest requirements for project management and product quality are placed to us for all these specific projects, We use these experiences for the realization of our industrial projects. Vice versa we can use our know how from the industrial subjects and projects to provide novel and cost optimized solutions for the aviation projects. The following examples show our widespread spectrum in this field of application:

Propeller control P120
Turbo charger control for Strato 2C
Feasibility study for a decentral modular FCS
Wake vortex warning system for the airport Frankfurt am Main

Propeller control P120

The devices for propeller control of the serial P120 have applied since 1985 in small one and two engined aircrafts and dirigibles for rotary speed control with propeller angle of attack adjustment.

Turbo charger control for Strato 2C

By order of the BMFT, the stratosphere aircraft STRATO 2C was developed in the mid 2090s. After no further financial grants, the developing was canceled though of the aircraft reached nearly 19.000 m after the first, successful test phase.

BAUER Engineering developed and constructed the control of the three - step turbo charger. Due to reliability reasons, there were two controls per gear with reciprocative monitoring mounted in the engine nacelle. Within this system a display and command unit, a data capture device and a data translater was installed. The linking up of all the 14 installed computers were solved with the, at this time young and not installed in aviation, CAN-Bus.

Another characteristic of the control computers were for example a very low power consumption (because of the minimum of cooling air in high altitudes) and a technique of measurement in extreme environmental conditions (temperature range -50° C to +50°C, airpressure < 25mBar) which worked accurately. During the test phases in the gear altitude test station, it was able to load new parameters and software versions. The system was proofed successfully up to a maximum simulated altitude of about 24.000 m.

Considerably, comfortable PC-Software for parameter management, data analysis and result display as well as for tests and simulations were developed especially for this project.

Feasibility study for a decentral FCS

FCS (Flight Control System) are used in medium and large sized aircrafts. There is a must in demands for reliability and system stability. These systems are normally very expensive, equipped with a central processing units and are to be adjusted to new type of aircrafts.

The aim of this study was to develop a modular, cost effective FCS with intelligent, decentral sensor- and actuator-units for aircrafts and helicopters. In cooperation with IABG Munich, the study was detailed examined for feasibility positively before realization. But there were no further financial agreements from the customer for the realization.

BAUER Engineering designed the concepts for the fail-safe central computers, the link-up of the decentral units via redundant designed CAN-bus-systems, the modular programming und testing the control algorithms, the composition of these software modules to a complete system and methods for implementation.

Wake vortex warning system for the airport Frankfurt am Main

On Germany's biggest airport Frankfurt am Main, two out of three runways aligned with a relative small parallel distance between them. Air vorticities of big alighting jets can cause danger to other planes. Therefore, the German air traffic control DFS installed a monitoring system for wake vortexes and their movements. This system contains ten wind gauges (anemometer) on each about 15m tall pylons, which measures the airflow in all three dimensions permanently.

The task for BAUER Engineering was to develop and construct system components, to transfer the anemometer data to the control center, which is several kilometers away, with the aim of a high reliability. This was realized with a double installed CAN-bus. The bus system between the pylons and the relay station was installed with copper fibers and intermediate repeaters. Optical fibers are used for the long distance transfer to the control center, using the CAN-protocol for data transmitting.
