‘Keyhole Surgery’ on RR Jet Engines

RR Trent Engine__#1_  Endoscope_Medical_


MiRoR (Minitarised Robotic System for In-Situ Repair) robotic technology is moving at a pace at Rolls Royce with the introduction of ‘snake’ like robots that can enter inside an in-service jet engine of a commercial or military aircraft and make repairs remotely controlled by a highly experienced and qualified engineer, who is based elsewhere in the world but most likely at Rolls Royce in Derby. Development of these robots is progressing significantly at RR’s facilities in Derby, the technology will save a lot of time and cost within maintenance and repair contracts, improving profit margins.

At Derby they have CAD models to supplement the views from on board cameras on the snake like robots that have 25 degrees of freedom of movement controlled by algorithms assisted by camera & sensors, as they move and contort through narrow gaps.

Presently engineers go on site and investigate stricken planes with a borescope similar to a medical endescope to peer inside the engine through tiny access holes. Repairs ideally are achieved with the engine in-situ using specialised miniaturised tools to clean up engine blade defects for example through the same access holes. This is very skilled work, but the robotic technology enables the process to happen remotely by the same engineer. This technology is also being used in other sectors and is enabling access to environments normally detrimental to humans.

The world is changing and the way we work is changing, this technology is a definite improvement.

Hope you have a good month

All the best,

Hyperloop Transport – non friction !

Hyperloop Pod_#4_  Hyperloop Pod_#5_

Hyperloop transport is gaining momentum as a future transport system. It is environmentally sustainable and cost-effective. It consists of passenger Pods elevated by magnetism or pressurised air bed, within low pressure transport tubes, these then travel up to near supersonic speed ~ 800 mph, driven by linear induction motors or fans. SpaceX are encouraging further innovation in this area by holding a competition in January this year at their Hyperloop test track for 27 teams from across the world.

SpaceX and Elon Musk head of Tesla mentioned hyperloop transport to South Korea a few years ago, who have since signed a deal with HTT, a start up company from Calfornia, to develop a hyperloop line between Seoul and Busan. If it is successful, travel time will come down from 3 hrs by bullet train to just 30 mins ! The energy used will be much less than high-speed rail and cost of infrastructure would be less than half. Part of the deal includes co-operation with Hanyyang University in Seoul, starting initially with the build of a full scale test bed.

Elsewhere Dubai, US, Czech Republic, China, Indonesia, and India are all investing in hyperloop projects. The annual market is expected to grow by 50% from 2022 to reach $6.34 billion by 2026 – as reported from Markets and Markets. The first hyperloop is expected to be launched in 2022, providing 12 minute travel between Dubai and Abu Dhabi.

The science fiction movies often used to portray this type of travel and now it seems has become today’s reality.

I wonder what’s next?  Swish, Swish doors and silver one piece suits and interesting hairstyles !! Let’s hope not !!

Hope you have a good month,

All the best,

I, Robot – it’s nearer than you think !

Cobot #3_  Cobot #1_

Collaborative robots called ‘cobots’ are growing in popularity in manufacturing companies over traditional robots used on production lines. The main differences between them is that cobots are smaller and more versatile, they can be taught new tasks in hours instead of weeks, they are less expensive – average price is $24,000 compared with $50,000 to $75,000, and they are not within a physical safety cage or invisible kill-switch safety zone, but are free to roam within a given area.

Their movement and appearance are becoming more characteristically human to instill trust from humans as they work together. Monitors represent faces with almost cartoon like eyes and facial expressions, and they turn towards an object as their arm approaches it to carry out a certain task. Arm movement speed & range copy the more restricted movements of humans to not shock or cause fear in humans, but to gain trust. The Audi and Ford factories use collaborative robots and the factory workers have dressed them up a little and given them nick names ! The relationship between man and machine seems to be getting closer !

Jim Lawton chief product and marketing officer at Rethink Robotics, predicts they will also be able to share information with each other across the cloud network to help them learn from each other and improve, and that very soon they will be in every manufacturing environment in the world and eventually in our homes.

It’s amazing how some elements or themes of yesteryear science fiction films start to appear in present day society.

Hope you have a great month

All the best

3D Printed components in Aerospace

RR Trent Engine__#1_   RR Trent Engine__#2_

GE Additive Centre in Ohio 3D prints parts for it’s aircraft engines ! Profound as that may seem, where reliability and caution in manufacture is paramount in the aerospace industry, it is today’s reality. In fact 35% of components in it’s Advanced Turbo Prop engine are 3D printed. Not just GE are moving in this direction, Airbus are making the largest ever 3D printed cabin component in the form of a partition wall that locates between the seating area and the gallery.

Advantages of 3D printing are: weight saving, zero material wastage in manufacture (compared with ~ 90% wastage for traditional methods), shorter lead times from design concept to finished operational part, and lastly but most importantly the  manufacture of complex parts that cannot be made any other way.

Materials that can be printed are: plastics, carbon, aluminium, titanium, stainless steel

3D printing is a collective term for a host of different additive manufacturing methods to make a part. A 3D CAD model is sliced up into layers – as thin as 20 to 30 µm. A machine then uses these to build up a 3D design. Methods fall into 3 different categories:

  1. Direct Energy deposition – a nozzle pushes out a solid wire of metal, a laser beam shines directly on to material creating a focused melt pool on top of a substrate. Robots manipulate these to create 3D part.
  2. Powder-bed electron beam melting – an electron beam focuses on a powder bed of material. As it moves the beam melts the powder forming a solid layer. Layers build and part is created.
  3. Fused deposition modelling – most commercial – a nozzle heats up and deposits a thermoplastic filament to create the part in a number hours. A traditional method would take weeks.

Rightly though, some large companies are cautious, such as Rolls Royce, in adopting this technology for mission critical parts in their engines because mechanical properties are still suspected to be inferior to parts made from tried & tested manufacturing methods – fatigue stress in service is probably the highest concern. Potentially lives are at stake here and reliability is paramount, and any failures ultimately hit reputation and then share price.

Conversely though Siemens are 3D printing turbine blades for their gas turbines that run at twice the speed of aircraft engines at a temperature of 1250 °C ! Injury or fatalities due to a failure though, would be near to zero or limited in this case.

As the technology becomes more accepted & proven, I think we can expect more of our aircraft to be made from 3D printed components, producing lighter and less expensive aeroplanes !

Hope you have a good month

All the best

Car weight is now becoming material !


Al Car Structure_  Al Car Structure_#3

Al Car Structure_#2  Al Car Structure_#4

An age old concern that is now higher on the agenda for manufacturers is overweight vehicles. Traditionally cars have always been made from steel for the structure & ‘body in white’ components, with plastics for trim and other aesthetic and non stressed parts.

The benefits for lighter vehicles are multiple – reduced fuel consumption, emissions, greater performance, and for electric cars greater range which can be a sticking point for potential customers.

Kieron Salter MD of consultancy KW Special Projects, says “lightweighting is a challenge for the two hot areas of chassis & body in white, as well as for the powertrain & other structural components”. New materials with accompanying new manufacturing techniques are often more expensive in general. New emerging companies though can benefit from this new demand, because unlike the established competition they don’t have significant capital investment in traditional production infrastructure and can flex more easily into newer technologies.

The general trend is for a greater use of aluminium, and composites such as carbon fibre already used on more expensive sports cars, which have a high strength to weight ratio. Magnesium and titantium are also being researched & developed – magnesium is 33% lighter than Aluminium and 75% lighter than steel.

New traditional materials are also being introduced, such as ‘low density steel’ – higher strength steels that can be produce lower part volumes and therefore weight. An example of this is being carried out by WMG consultants for Jaguar Land Rover and Aston Martin, known as the Ultran Project. Powertrain gears are being made lighter due to higher strength steels, and new lightweight exhaust systems that are matching the performance of the old ones and are 50% lighter.

With new materials comes new manufacturing challenges and one is the joining process. Aluminium and steel for example cannot be welded together and also there is the problem of galvanic corrosion in service. Companies though such as General Motors have come up with new innovative joining techniques, one of which is using adhesives on their production lines for their Cadillac CT6.

Another exciting move going forward, is the growing relationship between University Research Centres and manufacturers which is moving the automotive industry forward at a pace. Examples of this are: Mclaren and Sheffield University, Meridian Light Weight Technologies and Birmingham City University, and there are many more.

With the growing market share of electric cars the need for car manufacturers to reduce weight is now paramount to entice new customers to the new age of electric, without the stumbling block of low range.

Hope you have a great month

Cars recover energy from pot holes

Regenaritive Suspension_#4_                Regenaritive Suspension_#1_

Regenaritive Suspension_#2_


Where we live we have a generous amount of ‘pot’ holes in the road – the county of Buckinghamshire in the UK !

The automotive industry has developed car suspension prototypes that can reclaim energy lost by ‘falling’ into these irregularities in the road, and they are known as Regenerative Suspension Systems.

There are 3 types to date – ones using Linear Electromagnetic Transducers that convert kinetic energy into electricity – then secondly systems that convert linear motion into rotational motion that are used to power geared electromagnetic motors – then thirdly mechanical motion rectifiers (MMR) which converts linear oscillatory motion of shock absorbers into unidirectional rotation motion, in a similar way to electrical voltage rectifiers convert AC to DC power.

All the systems cost more to manufacture presently than traditional dampers, but over time they expect prices to tumble. Audi are a year or 2 away from perfecting their eROT system and replacing traditional hydraulic dampers with electromechanical rotary ones,  harvesting kinetic energy and converting it into electrical energy, leading to a reduction in CO2 and fuel costs. Tests have shown that on average 100 to 150W is recovered by eROT on normal roads, and up to 613W on rough roads!

Another advantage of these new suspension systems is that their ‘performance’ can be fine tuned to a greater degree than traditional ones – so a win win situation, there is just the challenge of costs and commercial viability in introducing this new technology – but the future does look positive despite possible bumps in the road or is it ‘pot’ holes !
