8Use Scenarios
Typical Use Scenarios for dSPACE Products
Aircraft Systems
Electric and electronic systems play a major role in
modern aircraft, and aircraft support and flight systems
are increasingly controlled and monitored by electronics.
At the same time, environmental legislation is forcing
companies to reduce aircraft weight and lower overall
fuel consumption. These trends affect a wide range of
aircraft systems, such as flight control systems (control
surfaces and cockpit controls), navigation systems, health
and usage monitoring systems (HUMS), and aircraft net-
works (AFDX, MIL-STD-1553, ARINC 429, etc.).
Use Case: Actuator Tests on an Iron Bird
This iron bird can easily run through a wide range of
flight situations and simulate a large number of faultsin the hydraulics, electrics, flight control system, and
actuators. The faults that can be simulated include
pressure changes in the hydraulics and component
failures.
Airframe
Modern airframes, including components such as control
surfaces, landing flaps, slats, landing gear, etc., contain
countless electric components. For example, control sur-
faces are activated by electric or electro-hydrostatic actua-
tors instead of hydraulic actuators. Iron birds aircraft
test benches are vital tools in developing these systems,
as they automatically and realistically reproduce any con-
ceivable flight situation. dSPACE systems play a central
role here, calculating models for real-time flight maneuver
simulation.
Each of the DS1005 boards has its own task to per-
form, such as calculations for the real-time simulationof flight maneuvers, the hydraulic system or control
surfaces, or autopilot functionalities like automatic
landings. One special strength of the dSPACE com-
ponents is their flexibility, which makes it possible to
adapt the test facility to new actuator concepts and
aircraft types with a minimum of effort.

Unmanned Aerial Vehicles
Unmanned aerial vehicles (UAVs) are being introduced in
many different areas, including surveillance, security, crop
monitoring, law enforcement, and even package delivery.
One particular challenge is autonomous flight in gen-
eral airspace shared with normal manned commercial
aircraft. To meet this challenge, high-performance envi-
ronment recognition and intelligent on-board real-time
Use Case: Researching Extreme Flight Situations
In this example, a UAV is used to study flight situa-
tions that would be too dangerous and too expensive
with a real aircraft. The ground-based flight control
system is implemented as a dSPACE system, which
provides the high performance required by the com-
plex real-time computations during test flights with
the UAV. The system processes the measurementvalues collected by the UAV and also the flight com-
mands in real time, supports the generation of data
for flight displays, and records test data for post-flight
analysis. The dSPACE system communicates with
the UAV over a high-bandwidth telemetry link. The
ground stations computer systems consist of two
DS1005 Processor Boards and several connected
workstations for display generation and data log-
Use Scenarios
ging. One CPU in the dSPACE system handles the
pilot inputs, manages the telemetry stream to and
from the aircraft, and calibrates and processes data
to drive real-time displays. The second dSPACE CPU
is dedicated to research control algorithms which are
invoked during the flight under both nominal and
failed vehicle configurations. These control algorithmsare routinely swapped out for different flight experi-
ments, and implement code developed and proto-
typed in Simulink using a simulation model for the
vehicle. The use of a secondary CPU for this code not
only provides a high level of computing power but
also allows the master CPU to monitor and isolate any
software faults, including code lockup, segmentation
faults, or unbounded behavior.
aircraft control software are absolute necessities. dSPACE
systems are perfectly suited for developing such systems:
for intricate tasks such as processing sensor data in real
time during actual flight, or testing the onboard systems
in virtual laboratory test flights, dSPACE prototyping and
HIL test systems speed up development, and help cut
costs and improve software quality and reliability.

Space Flight
When developing space flight technology, aerospace
engineers are constantly striving to push the limits of
what is technically possible. At the same time, system
reliability is their top priority, since an error in space can
result in expensive losses and delays, and have fatal con-
sequences. So it is imperative for system engineers to get
Use Case: Testing a Navigation System
In this use case, the dSPACE systems task is to simu-
late the atmospheric reentry of a rocket nose cone.
The dSPACE system allows complete preflight simula-
tion of the flight sequence after reentry, including
navigation signals, in order to test the interactionbetween all components. In the first test step, the
experiment setup consists solely of the dSPACE system
and the navigation computer. The actual navigation
devices inertial measurement unit (IMU), GPS, star
tracker are not connected at this stage, so their sig-
nals are all simulated by the dSPACE system. This test
phase validates and optimizes the basic functionality
of the navigation software. In the second step, the

it right the first time. Thats where dSPACE systems can
help. The typical applications of dSPACE equipment in the
field of space flight are in developing navigation systems,
satellite position controls, and propulsion (combustion
control, thrust control, vibration damping).

GPS and a GPS signal generator are connected
so that GPS navigation can be tested. The third step
(see diagram above) then connects the IMU, which
is mounted on an ACUTRONIC rotation table to simu-
late different craft movements. The integrated startracker receives a simulated map of the stars from
a Jenoptik sky simulator.
One special challenge handled by the dSPACE system
is to synchronize the measurement signals with the
navigation computers internal clock. This is particular
important because of the high velocities of the nose
cone during reentry, when time delays in GPS mea-
surements seriously affect the navigation solution.
