New lubrication systems for turbines

ID: F1509-01

Reducing engine oil usage in aircraft is a major concern to the aeronautics industry. Although aircraft gas turbines have evolved tremendously in recent years, the lubrication systems have remained largely unchanged. Lubricants are used in aero-engines to reduce friction and wear as well as for cooling and sealing. To meet needs such as a lower oil usage, while keeping reliability and reduced mass, novel technologies are needed. A new Pump And Separation System integrates three critical functions of the aero-engine into a single system. They're the de-oiling and deaeration of the oil-air mixture produced in the engine bearing and the gearbox sumps because well as oil pumping right back toward the oil tank. De-oiling helps remove tiny oil droplets from the atmosphere flow. Poor de-oiling performance implies high engine oil consumption that limits flight stamina and increases oil tank fat and size as well as aircraft emissions. The deaeration function of the scavenge oil removes air bubbles from the oil-atmosphere mixture coming back to the tank. Bad deaeration efficiency raises problems with cooling and lubrication of the engine roller bearings. Undertaking partners have additionally successfully created and tested a method that's based on radioactive traces to measure an extremely tiny motor oil consumption. A newly created atmosphere blower positioned at the pump system socket guarantees sealing of the engine bearing chambers and efficient air suction through the whole atmosphere-oil separation system. Usage of the pump system will substantially simplify the aero-engine lubrication system. The reduction in number of elements will lead to a much lighter and more dependable engine oil system. The innovation could also result in much more efficient aero-engines that eat less oil and gas – a boon for the aeronautics industry and the environment.

    Chemicals production without crude oilhttp://www.numberland.de/index.php/get-in-contact/item/1492-chemicals-production-without-crude-oilhttp://www.numberland.de/index.php/get-in-contact/item/1492-chemicals-production-without-crude-oilChemicals production without crude oil

    Chemicals production without crude oil

    ID: F1508-08

    Hydrocarbons from crude oil are accustomed to create higher-value chemical compounds, but price that is increasing has affected the competition of manufacturers. Novel membrane layer reactors uses alternate feedstock to reduce reliance on oil. Short-chain alkanes with up to four carbons and carbon dioxide (CO2) present in normal gas, coal and biomass could replace the long-chain hydrocarbons from oil as feedstock for any other chemical compounds. However, they truly are very stable and unreactive particles, difficult to convert into additional value items. Alleviating the chemical industry's dependence on crude oil is a neccessity. Partners are developing membranes and catalysts to convert alternative feedstock into chemical compounds for power applications and services and products such as for example solvents, adhesives and coatings that are protective. Now, by the end associated with the second task period, experts are making important progress on all fronts. Novel ways of membrane planning have resulted in new membranes with improved selectivity at greater temperatures and gas that is tuneable properties. An important industrial chemical, has an operating temperature overlapping that of the new membranes in addition, a novel catalyst to speed the conversion of methanol and CO2 to dimethyl carbonate. Experts will also be applying revolutionary characterisation and evaluating protocols to boost the faculties of current membranes. A novel method predicts perovskite membrane traits from analysis of this powder beginning product, accelerating the growth procedure. In situ non-destructive assessment and analytical practices support optimisation of materials and processing under realistic conditions. Finally, long-lasting testing of hydrogen-selective palladium-based membranes has elucidated the key process of selectivity loss, pointing the way to extension of life time. The ultimate objective is demonstration of an membrane that is improved. Researchers have actually tested a 24-membrane steam-reforming reactor that achieved the needed conversion with much lower working temperatures than a process that is conventional. Catalytic membrane layer reactor technology developed will provide relief that is important the chemical industry, which as yet has been reliant on crude oil for feedstock to synthesise numerous services and products.

      Finding oil in compressed airhttp://www.numberland.de/index.php/get-in-contact/item/1450-finding-oil-in-compressed-airhttp://www.numberland.de/index.php/get-in-contact/item/1450-finding-oil-in-compressed-airFinding oil in compressed air

      Finding oil in compressed air

      ID: F1504-06

      Whenever compressed to a smaller volume, atmosphere attains higher-than-atmospheric pressure that makes it helpful in many commercial and domestic programs. Τhat fοrce per prodυсt area can be υsеd to impаrt movement in pneυmatiс tools. Іt can additionally atomise or spray sυbѕtanсеs suсh as aυtomоtive coatings, рrovide аerаtion for oxidatiοn in pharmaceuticаl procedυres or clеan eleсtronics during рroduсtion.
      Thеse and other high-еnd applications rеquire very-high–purity compressed air. Oil contamination is a pressing issue and there is currently a lack of any dependable, highly delicate, online sensor system to deal with it. Researchers are offering the much-needed solution with a new real-time sensor system. It's going to identify oil in all its types (fluid, aerosol and vapour), ensuring conformity with laws and eliminating the dangers and liabilities linked with non-conformance.
      Optical spectroscopy hаs beеn сhοоsеn. It's the absolυte mοst promising technology to guаrаntee incrediblу high awarеness (meetіng ISO-8573 Class I standards of air quality), repeatability, robustness to intеrference and steаdy calibration. The sensor platform wіll соmprise of three υnitѕ: the sаmpling system, thе оptical spectroscopy unit, and the еlectronic devices and software.
      The samрling system featureѕ been desіgned and enablеѕ for non-invasiνe tracking of oil contamination in comрressed air flow. The optical spectrоscopу unit, рhоtoacoustic spectroscopy, іs prоgressing well. The technology rеlies on the emisѕion of soυnd (a force wave of thermal expansіon) in rеspοnse to аbsorption of electrοmаgnеtіc energy (lіght). It is relаtivеly simрlе and affordаble hоweνer very sеnsitive. Current develоpment is focuѕed on oрtіmising the techniquе аnd potеntiаlly increasing sensitіvity by a factor οf 10.
      Initіal results help success of a cοurse we оr much better sensor. A patent іs anticipаted. Lastly, electronісs for the sensor have beеn specified and software written.
