Last week saw testing across three areas taking place to either test components before these are fitted onto the X-Plorer 1 or to enhance our understanding of the mechanical behaviour of 3D printed parts.
The week kicked off with electronics checks to test the performance of sensors in environments more realistic to the anticipated in-service ones, check the wireless communication links and readiness of the Graphical User Interface (GUI). 5 sensors have already passed the checks, 1 is pending and issues identified with 4 of them are being addressed this week. The GUI was also found to respond and function well, with only a few bugs left to be sorted by our software engineers.
Finally, we conducted a series of preliminary mechanical tests on 3D printed specimen, manufactured in different orientations. The purpose of these experiments was to quantify the relation and degree of dependency of the 3D printing structure on the mechanical (tensile) capacity of the part. Apart from enabling us to observe the difference in failure modes, the tests have given us data that will be used to optimise and build more complex and accurate FEA models that are based on composite structures. The long-term objective is computationally model 3D printed parts more accurately, which is particularly challenging due to a number of factors.
Testing will continue this week, as assembly progresses. A failure of an LP shaft segment led to intensive work by several of our design engineers who have come up with an improved design. Even though re-printing the parts meant that just over 115 hours were added to the printing schedule, the new design is thought to offer multiple benefits and its immediate implementation will be completed by next week.
This months a series of tasks enter the last stages, as we've reach the last 16 of the batch of 260 initially scheduled prints!
Some adjustments are being made to ease final assembly and we will soon be able to share images from the assembly progress of the actual X-Plorer 1. In the meantime, we've put together a stunning animation of the virtual assembly, giving you a glimpse of the number and variety of components on the engine.
Vibrant colours and dramatic music aside, virtual assemblies are extensively used as part of the design process and are essential in avoiding interferences and other issues that typically arise when components from different teams come together.
The PCU was assembled in late December and consists of 32 components housed in a 3D-printed, custom-made casing. In fact, the main part of the casing was printed in one go, surpassing the compressor casing to become the longest single print, taking 58 hours and 30 minutes! The whole casing used up 125 metres of Formfutura's Easyfil PLA.
The PCU is designed to handle a range of compressed air sources and regulate it to the desired flow rate and pressure before it is injected in the X-Plorer 1 propulsion chamber via the on-board pneumatic assembly. The 21 high quality Camozzi rapid fittings are housed in the PCU, which alongside the 24 additional fittings mounted on the X-Plorer for operational and monitoring purposes were kindly sponsored by the Technomatic Group IKE.
In normal operation, the PCU can supply up to 100 litres of air per minute, monitored and adjusted using an impressive acrylic flow meter, courtesy of Cole-Parmer, leading manufacturer of scientific equipment.
Across the project, the manufacture of all core components is now complete! Assembly continues, as the first stators were mounted last week and the assembly of the drivetrain is expected to start next week.
The team will meet later this week for a briefing and to assess progress for the X-Plorer 2.

We are off to an exciting start to 2017 as all core components for the X-Plorer 1 have been 3D printed! Assembly has begun as the first 224 parts were completed on the 7th of January.
A trial to introduce parts with embedded metallic inserts is underway, and the manufacture of the nacelle will soon commence. The team will meet in two weeks' time to assess progress on both engines, and we expect that the core of the X-Plorer 1 will be assembled by mid-February.
For now, we would like to extend our warmest wishes for a happy and creative 2017!
We proudly present the complete design of the X-Plorer 1! After two years of hard work of 46 engineering students, JetX's first turbofan engine design has now been finalised.
Reaching this stage is of great importance for the organisation, as the process has been challenging on many different levels. Designing a sub-scale engine that obeys the theoretical models developed as closely as possible has taken considerable resources and adjusting all parameter for printability has offered an all-round engine development experience for everyone involved.
In the meantime, we keep pushing the boundaries and capabilities of our design. 12 new members joined the team in early October and will work with their respective teams to optimise the engine design and implement improved or more advanced features in the X-Plorer 2.
The second engine of the X-Plorer family will be optimised in terms of ease of assembly and reliability in the next couple of months and then further improved in terms of performance, based on testing results from the X-Plorer 1.
Let us know what you think of our design and make sure you stay tuned for production updates as well as more content from the current engine!
Last year marked our most successful recruitment season to date and we are ready to welcome even more young engineers in all five teams!
This year we have a working design for the X-Plorer 1, a steady flow of 3D printing and 6 new sponsors standing by our side. We are building the strongest team to complete the X-Plorer 1 and work on optimisation.
If you are interested in aerospace, rapid manufacturing, fluid dynamics and, of course, jet engines, JetX has a lot to offer. If you have plenty of experience and want to put it to the test or if you are a fresher keen to learn new and fascinating things, submit your application as soon as possible by following the link below.

From shaft connectors to casing sections and from nozzle guide vanes to fan blades, the list of the first 100 parts to be prototyped has had it all!
All parts up to this point have been prototypes and test that will not be part of the final engine model. Team members from the Compressor, Turbine, Power Transmission and Exhaust teams have been designing these parts and 3D printing has been fully utilised to help our engineers optimise their designs, as well as interact with these. Needless to say, many of those were tested to their limits in the name of engineering and have ended up broken, only to be replaced by improved versions.
With an average print time of 3 hours and 5 minutes, our Overlord has consumed over half a kilometre of plastic in the process! The record for the longest print so far is held by a section of the inner casing which took just over 48 hours to print.
It is not long until we begin manufacture of the final components and we are all looking forward to that! Don't forget that you can always check the latest 3D printing numbers here.
This is the first in a series of videos highlighting the different aspects of the project.
The design is where it all begins! Take a look at some of the designs that made the cut from theory to prototypes and have a place in the final working assembly.

Following the end of the spring exams, all teams resumed work on the project. At a team leaders' meeting that took place last week, we checked progress across all teams and the heads highlighted the pending tasks.
The findings from printing trials that took place in the last couple of weeks were discussed to make sure a common strategy is followed for subsequent design changes. This week also marks the crossing of the 200-hour mark for 3D prints. Having already prototyped 94 parts, the trials continue and it's not too long until the final parts enter the printing queue.
With the Printed Circuit Boards (PCBs) ready and assembled, the graphical user interface is being finalised.
The Engine Monitoring System (EMS) is coming together ahead of schedule and our Electronics team has calibrated and tested all sensors. The EMS consists of 10 sensors that will be continuously monitoring and logging vital performance data of the model while testing, including air pressure & speed, shaft speed and temperature.
To enable wind tunnel and remote testing, the X-Plorer will be able to transmit the real-time data wirelessly. It comes with a built-in APU to eliminate the need for a wired power supply and two 100MHz ARM micro-controllers are employed to process the data.
Design 90% complete
We have also created a dedicated page, where you can find out more about the positive impact you can make, as well as details on the donation options that you have. Every little counts and we do believe that all together we can make a big impact on aerospace education!
Our event on the Bloodhound on Monday was a big success with students from several universities and professionals attending.
In two and a half hours, we got an insight of the Bloodhound, the manufacturing process of the fastest wheels on the planet, as well as the car's jet engine, the EJ200.
We would like to thank John Mason from Rolls-Royce in Bristol and Roy Yuile from Castle Precision Engineering here in Glasgow for attending the event and giving two very interesting presentations. Thanks to our co-organisers, the Young Members' Panel of the IMechE and the University of Glasgow, we were able to deliver an event on cutting edge engineering and one the UK's biggest engineering challenges which was highly attended.
For future events keep an eye on jet-x.org/events or follow us on Facebook and Twitter.
Members and leaders across five teams came together last week to assess progress up to the end of 2015 and get updates for the strategic planning leading to the completion of the X-Plorer.
Following the board's news, each team gave a presentation to the club, enabling everyone to get an in-depth look into other teams' work and current standing. The presentations were part of our continuous work towards bringing people from different backgrounds together and showing the bigger picture of what we are working on.
The meeting followed the publication of interim satisfaction levels, where 94% of the members said that they are very glad to be part of JetX and 88% have found the project to be a good chance to develop their personal and professional skills.
We are also very happy to welcome two new sponsors, the Dutch Formfutura and Plastic2Print who are supplying us with 3D printing supplies.
Rolls-Royce will be represented at our upcoming event for the Bloodhound project on the 25th of January.
We will find out more for the EJ200, the engine used up until now for the Eurofighter Typhoon only. The EJ200 is the main engine of the Bloodhound, which will be supplemented by a hybrid rocket engine to push the car beyond 1000mph.
As it has already been confirmed, engineers from Castle Precision Engineering will give us a presentation on the design and manufacture of the fastest wheels on the planet!
Registration is still open at jet-x.org/events.
