Thank you for the introduction

Professor.

So good afternoon, everyone.

My name is Raffaello Terenzi.

And in the following slides I'll present the most relevant work that has been done within

the IPRO project in the context of airship design.

So I was going to start with an introduction

but given the environment I'm going to cut

it a bit short.

I just want to focus your attention on some that are the main advantages

of course

of

LTA platforms when compared with fixed-wing aircraft

helicopters or even satellites.

In particular

what we find is that obviously the advantages in terms of complexity

production

cost and endurance

makes the LTA a very viable solution.

So why do we link it with the electro-aerodynamic propulsion

this rather strange and new research

that has been

let's say

studied for the last 15 years?

Here you can see

for example

a prototype which flown

this is the MIT airplane which

flew in 2018.

And well

starting from the main features

this kind of propulsion system is actually

very sustainable, meaning that there is no emission.

It is quite efficient.

And most importantly

there are two main aspects that characterize this kind of propulsion

system that are the being in a solid state

meaning that there are no moving parts whatsoever.

And also it is very easy to manufacture.

Everybody can do it.

This allows us to say that it is

in fact

a very reliable technology in terms of both

production and employment.

And it actually shares mostly all of the advantages of LTAs

which are complexity

cost and endurance.

This means that there is actually an inherent

let's say

compatibility between LTAs and
