Hephaestus is an independent startup that aims to make space accessible to everyone.
There are no limits of space and imagination above our heads.
It belongs to everyone and with the right means we can exploit its almost infinite resources.
The first step is to obtain the means.
This is where I, you, us come into play.

HOW
HOW
We have the tools and they are just a click away:
rocket modeling enthusiasts every day launch models kilometers high into the sky and often even with cutting-edge technologies.
Suffice it to see how Joe Barnard, the founder of bps.space, made a dream come true by building his personal thrust vectoring control (TVC) in scale and fully functional.

I'm offering you a preferential way to learn.
Launching a rocket today is not that difficult and complicated. I have studied a lot about it and am ready to make available everything I have learned by clicking the link below
(none of this is paid, don't worry).
what do we do?
what do we do?
hephaestus can boast of a subdivision into three autonomous departments that deal respectively with developing the avionics systems, those of propulsion and finally the structure of the rocket itself.
propulsion
propulsion
This department is responsible for the design, research and development of everything related to rocket propulsion.
The engine is made up of two or more chemical components (an oxidizer, a propellant and possibly a catalyst) which, when subjected to high temperatures, ignites and produces a strong amount of pressure (and heat), which if redirected to a nozzle of output, allows us to generate thrust. This department will be in charge of testing all the most important combinations of propellant / oxidant and possibly some catalysts. In addition to the more practical part, the members will have to develop the design of the support that will contain the motor itself. The choice of materials naturally implies a "study" of computer simulations, in order to avoid exceeding the breaking points due to excess pressure or temperature.
avionics
avionics
This department is responsible for the design, research and development of everything related to the electronics of the rocket.
The members will be required two main tasks: on the one hand they will have to design a pcb board (like this one), on the other hand it will be necessary to write a code that is able to actively stabilize the rocket during the entire ascent phase. The purpose of this department is in fact to provide for all the activities of the rocket. From stabilization, through data recording up to the ejection of the parachute. It will therefore be necessary for the participants to study some notions of mathematics and computer science and then apply them within the software. As regards the design of the board, it will be enough to learn how to use a specific software for this type of use and more generally the dynamics of the components..
structure
structure
This department is responsible for the design, research and development of everything related to the structure of the rocket.
The participants of this department will have to deal with the digital and practical design of each structure of the rocket and of each plant that will be used in the tests of this. To do this, where a short learning part of 3D design, members will use tools and materials starting from the 3D printer up to carbon fiber, and, before building each section, they will determine which is the best material according to durability criteria, weight, price, ease of use and replica etc. This department also has the task of carrying out flight simulations (in collaboration with the electronics department), as the stability and correct aerodynamic set-up is a consequence of their work. To do this, semolina softwares available for free online will be used.
each of these departments therefore works almost independently from the others (except in cases of collaboration between them), with the advantage of speeding up the processes and targeting the individual goal of each, thus avoiding having to learn too many things and in an inefficient way .
what we aim for?
what we aim for?
Our goal is to create a rocket, yes, but not just any one:
we aim to create an active and intelligent stabilization system.
This must be able to determine by itself, in a continuous loop, if the model is losing stability and moving out of its axis, and then correct the direction of the thrust vector provided by the motor.
This certainly requires a lot of mathematics, physics and the same desire to learn how to translate everything into a language understandable to our on-board computers, as well as structural design skills (as in the case of the TVC you have just seen) and propulsion (spoiler: without that the rocket does not rise).
sO ARE YOU GOING TO SEND IT TOdHaMOOON?
sO ARE YOU GOING TO SEND IT TOdHaMOOON?
Keep calm.
Space means crossing the Karman line (> 100km).
I would say no.
The goal of this project is not precisely to create the most powerful rocket possible and launch it at km and km of altitude.
-"why?"
simply because it would not make sense: if our goal is to develop and test electronic systems in fact the most logical and intelligent thing is to keep the model at close range, so as to never lose eye contact. Sending a five-foot-long missile to one-and-a-half times the speed of sound may sound cool, yes, but for our purposes it makes no sense or usefulness.
