Descripció del contingut i pla d'activitats:
The project will consist in the preliminary design of a new type of cruise missile to be used within the hypersonic regime. The approach will be a holistic one, taking into consideration all aspects of the design, ranging from mission design to structural requirements, propulsion needs and aerodynamic optimisation.
The work plan will consist of:
1) literature review
2) Mission design requirements and constraints
3) preliminary design and external aerodynamics evaluation
4) structural design for integrity and light weight
5) material selection
6) choice and dimensioning of an adequate engine.

 
Overview (resum en anglès):

In this project, a hypersonic airbreathing cruise missile is designed through an optimization
process. The main use of this futuristic weapon technology is to be employed against
enemy ships while being launched from an Mk-41 VLS launcher, the most widespread
VLS in the world.
In this optimization process and for this type of missile, Genetic Algorithms and Monte
Carlo simulations are used to find an optimal solution for the rocket booster engine, the
scramjet engine, aerodynamics and warhead sizing. With this data, trajectory, stability and
manoeuvrability is studied to determine the performance of the missile. Other aspects
concerning the missile materials of the airframe and dome are discussed on a qualitative
way and no structural analysis is studied within this project.
It should be noted that hypersonic weapons are mature technologies, and the only information
about them are research papers regarding their aerodynamics and propulsion systems.
Then, the only built hypersonic vehicles are experimental, meaning that the baseline
data to start design process scarce. This brings a great challenge to this project, where
creativity and the use of analytical expressions for rapid missile synthesis and conceptual
design is a must.
On the other side, due to the complex behaviour of hypersonic flows, this adds difficulties to
our research since most of the methods employed are numerical, which can be calculated
easily on a CFD in the final stages of the design, but they are not fast enough to be
implemented on the initial stages of design. The final results prove that the methods
employed for initial sizing are accurate enough to model a CAD design which can be used
as a baseline for future research in this technology.
To conclude with, the final results obtained with the algorithms helps us to understand
the effects on design, especially when flying at high Mach numbers where the classical
configuration of airframe, wings and tail must be radically redesigned to more aerodynamic
efficient bodies such as Waveriders.
Regarding to the optimization process, objective functions were changed manually to find
better results at each iteration of the optimization process but better techniques such as
local search methods used in artificial intelligence could be employed.
