The
following pictures show some examples of
our products and the steps necessary to
create them.
Aviation:
landing flap drive control unit We have developed the landing
flap drive control unit which can be
easily adopted to different tasks and
requirements. The shown version (according
to RTCA DO-160) operates with 28 V and up
to 15 A.
Aviation:
LAPAZ - actuator electronics for flight
control system (with Stemme AG)
We have developed the actuator
electronics for an Automatic Flight
Control System (AFCS). The flight tests
during summer 2010 were very successful.
Aviation:
landing flap drive system We have developed the landing
flap drive system for a business jet
aircraft (Fowler flap, spindle force 12
kN resp. 2700 lbf).
Aviation:
landing flap drive system We have developed the landing
flap drive system for a business
turboprop aircraft (Fowler flap, spindle
force 4 kN resp. 900 lbf).
Aerospace:
actuation system for a spacecraft
technology vehicle We have designed an actuation
system (a module with four actuation
units) for the control of the reentry of
a spacecraft technology vehicle.
Consulting: thermal
analysis
For the safe operation of electric motors
it is necessary to know the thermal
limits of operation. In most cases this
can only be done by experiments.
Electronics:
actuator electronic unit for a flight
control system
The actuator electronic unit was
developed for a flight control system.
Besides the key function of controlling
the position of the motor there are
numerous protective features (e.g. a two-staged
brake chopper) which are well beyond the
requirements outlined in RTCA DO-160.
Actuation
system: rotary actuation system with
brushless servo motor (BLDC) and digital
signal processor (DSP)
The combination of a modular actuator
with a DSP offers a flexible adaptation
to customised tasks.
Concept:
concept of DSP software The integrated development
environment (IDE) for assembly and C
enables very simply the testing of
algorithms (e.g. controller). The upload
of recorded data helps too.
Design:
test stand for actuators The assessments on key
performance and reliability data is
demonstrated in test stands which are
equipped with adjustable load device.
They duplicate the conditions in the real
environment (here: landing flap drive
system for an aircraft) and are equipped
with a variety of sensors.
Design:
development of hard- and software
The design process of an actuation system
also comprises the development of the
hardware (printed card boards, wiring
harnesses) and the software (control
algorithms, interfaces) to drive the
motor and monitor the sensors.
Laboratory:
measurements on an injection pump
actuator ("fly-by-wire")
Electric actuation systems often replace
manual actuation. In aircrafts this is
called "fly-by-wire". This
actuation system is part of a diesel
engine and actuates the injection pump.
