Job description


Airbus is a global leader in aeronautics, space and related services. In 2019 it generated revenues of € 70.5 billion and employed a workforce of around 134,000. Airbus offers the most comprehensive range of passenger airliners. Airbus is also a European leader providing tanker, combat, transport and mission aircraft, as well as one of the world’s leading space companies. In helicopters, Airbus provides the most efficient civil and military rotorcraft solutions worldwide.

Our people work with passion and determination to make the world a more connected, safer and smarter place. Taking pride in our work, we draw on each other's expertise and experience to achieve excellence. Our diversity and teamwork culture propel us to accomplish the extraordinary - on the ground, in the sky and in space.

Job Description

Are you looking for an internship or a bachelor thesis? Would you like to discover the work in our company? Then apply now!

For Airbus Helicopters in Donauwörth we are looking for a motivated intern (d/f/m) within our Engineering - Guidance & Controll team as a dedicated support for the duration of 5-6 months.

Start date? April 2021

Working time frame? Full-time with 35 hours per week (in flexitime)

What do we exactly do?

Rotorcraft occupants experience significant comfort of ride reduction especially during flight in turbulent environment or due to vibrations during flight with the main rotor as primary source for mechanical excitation. This inherent rotary wing source for vibration generation is a feature not known to other kind of aircrafts. While comfort can be a significant competitive advantage on the helicopter market, health is regulated by the EU directive 2002/44/EC and implemented by national laws.

The research project CORINNE has the goal to improve the comfort of ride for crew and passengers by modification of the autopilot control laws. To achieve this goal, the following steps are required:

·  A definition of what comfort of ride means to crew and passengers
·  Increased knowledge of the aircraft dynamics that need to be controlled
·  Improvement of the existing control law with respect to comfort of ride

Classic helicopter simulation as used for autopilot developments, do not model vibrations, neither coming from the rotor itself or induced by structural modes.

A part of the second step, the improved knowledge of the aircraft dynamics, has been prepared within sophisticated closed loop software simulations. New flight mechanical models provide the detailed accelerations and inertial velocities of sensor mounting points at different locations in the aircraft. The classical sensor models that provide flight state data to the autopilot system, have to be modified in order to operate with those location-specific data.

What can you expect?

In this Bachelor thesis or internship, three different sensor models (Inertial Reference System, Inertial Standby System, Global Positioning System) shall be updated in order to model the proper lever arm correction. The local sensor data (3D-velocity and –acceleration vectors) at the mounting point has to be transferred to a different coordinate frame that is specified by a three-dimensional lever arm and pointing from the mounting point to a reference center of gravity location.

After the theoretical analysis of the transfer function, the models (implemented in C and C++) have to be updated accordingly. As a result, the full closed loop simulation needs to be evaluated to show no regressions compared to the original reference simulation, yet then with the evolution to provide additional vibration sensor signals to the autopilot.

As an optional extension (e.g. for a Bachelor thesis), an additional verification could be made with an analytical comparison with existing flight test data.

What will be your scope of work?

·  Literature review about reference frames and lever arm kinematics
·  Development of mathematical models for corrective functions
·  Implementation of the functions into the inertial sensor models
·  Implementation of the functions into the GPS model
·  Integration of the updated models into an existing closed loop software simulation
·  Evaluation of test bench data
·  Optionally: verification of improved bench test results against existing flight test data
