Text lecture 8a Materials Introduction
This is the first of three short lectures about materials and production. As you will see there
is quite some interaction between these two. Also a third entity, the shape or d
Text Lecture 6e Demo Paper Airplane
So the handout you got with all the formulas, you don't have to know, because this handout
was given to you for another purpose. And that is simply to fold a paper airplane out
Text Challenge 1 - Weather balloon(s)
Standing here, in the market square, the central square of Delft, in front of the tower of the
"Nieuwe Kerk", the New Church.
This tower is actually 108 meters high and as we'v
3 System Architectures for Automated Vehicle Guidance Concepts
Details of the necessary specialist modules for situation interpretation were presented. The proposed design makes some exceptions with regard to the Rasmussen
model, e.g. the sensory input
The next big step after networking within the vehicle itself is networking with the
environment. The vehicle can be connected to the internet, to the infrastructure and
to other vehicles, e.g. via Vehicle2X (V2X) communication.
Fig. 4.1 Networked system of function units
The basic aspects in developing the system architecture are the deniton of communication signals, interfaces for
The major difference in dening the requirements for the eco2 DAS system architecture is the absence of user requirements and logical system requirements that
address dened functions of a system. The approach is not to dene what the eco2 D
guidance levels according to Neunzig (2003, p. 20). For a more precise description,
the stabilization level has to be considered as well.
On the navigation level the driver affects the transport mission by planning and
choosing a route. B
that result in efcient drive train/engine operating points. These functions can handle
simple gear recommendation or complex hybrid operating strategies.

Based on the inuence analysis
Energy Conversion Model
In this context, the concept of an arbitration unit is useful. The arbitration unit
decides which system has the highest priority to affect the related controls. In a critical driving situation, for example, emergency brake commands have
Text Lecture 8e The limits of speed
In the previous lecture we have seen that the speed of sound is not a real limit for
aerospace. You may ask: are there any limits to the airspeed? This lecture is about the l
Text lecture 7c - Propeller engines
So in this lecture we will discuss propeller engines.
The last time we look at different engine types and we focused already on airbreathing engines.
But when you have the energy
Text lecture 9a - Ground effect vehicles
Welcome in this lecture where we will discuss the final topic of the first module of this course.
In about four videoclips we will discuss the special vehicles, what are they?
Text lecture 6d - Stability
So lets have a look at what stability really is, and that is what we will do in this lecture, we will look
at two types of stability.
The first one is static stability, and that is t
Text Lecture 8b Aerospace Materials
In the previous lecture we saw that materials for products and structures can be divided in
four main groups: metals, polymers, ceramics and composites. Two groups were not useful
Text lecture 9c - Exotic vehicles I
In the last videoclip we saw how difficult it is to control a tiltrotor.
But this combination of a fixed-wing airplane and a helicopter is very tempting and there are other
Text lecture 9b - Helicopters
So lets continue with helicopters as our special type of vehicles.
There is always some animosity between fixed wing pilots and helicopter pilots (from their
communities on both sides) and
Text Lecture 8d Exploring the limits
In this clip we will discuss the exploration of the limits of aircraft. During the second World
War, the technology of aviation developed very rapidly. New concepts were created l
Text lecture 7b - Airbreathing engines
So in this clip we will have a look at engines, what is an engine really, what does it really do?
Well basically an engine is an apparatus which converts heat (by burning fuel
Text lecture 7a - Propulsion
Welcome! The lectures until now have discussed many forces and some moments.
For instance the stability and control, the last lecture, we looked at the moments (especially the
Text Lecture 8c - Production
In this lecture about materials I will focus on the production of components. You will see
that there is a big interaction between material properties on one hand and the production
Text lecture 7e - Jet engines II
In the last clip we concluded the lecture with asking ourselves the question why engines have
become so big?
And that is what we will have a look at in this videoclip.
So we saw
Challenge 3 - Water rockets
So this week we also discussed the propulsion,
and weve learned that the force of the propulsion (the thrust force) can be calculated by multiplying
the mass flow times the exit speed
Text lecture 7d - Jet Engines I
In this video we discuss the jet engines.
In the video before, the propeller clip, we discussed the piston engines to explain the principle of
how heat can be transferred into mechan
Text lecture 9d - Exotic vehicles II
Another type of special vehicles which we still have to see become operational are the so-called
personal air vehicles,
or you could also referred to them as where is my flyi
Text lecture 6f - Aircraft oscillations
So we looked at the longitudinal static stability for a standard configuration of an aircraft like this
and today we will discuss the standard periodic moments/ oscillations
