Project AIRBUS Prototlvoe neetins 30th Novsber and Ist DccR?~e~ 1S88 General eoncludinn Doi?trlauertionr A) More specific Information is needed on how PRE#I~ER works : how energy Is provided, burning daracter, temperature and sequence of nicotine release, aerosol generation and stabilisationl flavour, filtration and cooling, 8) 'Ihere is potential for the integrated moving furnace eoneept, which amy be easier to design if a non buning down version is used, Some key experiments and calculations need to be done, C) h it possible to find gaps in the PIB1IE,P patentll O) Key laboratory experiments are needed to define nicotine release from materials, E) Is it pcrsible to use tO olld~tioo as a source of heat? Fl There appears to be potential in using coaxial fitters, Agreed Action Points A~ilON 1, Three general types of AIRBUS prototype were Identified : (a) BATCF 'modified PREHIER1 design (b) Integrated toying CurnacelcPaxial, - either consumable or non-consumable (ccnsumable is a device which changes as It is smoked and is not necessarily flickable), (c) Sequential design, using a non-PRWIER heat source and needing aerosol elution andlor heat to aid the elutlon, 2, For the BATCF 'modified PRUIIIEP' design, A,1, Heard will ask E, Kausch to allocate 3 nan weeks' effort to consider further this design, A,L, Heard Assuming this time it allocated, BAtCF will (a) identify gaps In the patent literature (b) consider other materials to use In the capsules - although no experimental wort will be done, W, Schnelderl This should be done by 13th January 1989, 6, RudPlph -2- ACTION 3, For the integrated movlRg furnaeeleoaxial design, it was agreed that the inner tube could be made by an extrusion technique or be spirally wound, (a) J,R Luke and R, Ocnler will decide what potential fuels to use in the peripheral regions of the design, and these will be supplied by BATUKE to DaN before Christmas, J,A, Lute (b) Some potential aerosol-generatfng materials for use In the inner tube will also be supplied to BaW by BATOKE, J,A, luke (c) P,O, Care will either supply to 8&I~ or obtain further intonation on,sateri~l (e.g, perlite-based) which can be used to make the inner tube itself, ideally, tubes of differing thicknesses should be supplied, P,O, Case (d) Combinations of outer fuel and inner aerosol-qenerating material will be tested in B51J, In addition, BWJ will test the potential of the fuel and inner material separately : (i) To test the fuel, use standard PRE~IER capsules In the inner tube and measure temperatures inside the Inner tube and assess burning behaviour of the design, (ii) To test the inner aerosol-generating material, use standard B~ fuel in the periphery and measure nicotine delivery, etc, of the design, R, Denier (e) Calculations will be done using the SULTICELL computer model to assess the flu characteristics within the inner and outer regions of the design, as a function of impedance properties of the materials, (for these calcuations, initial measurements will be made of the impedance of PRERrER capsules in the inner tube, and the sheet material for use as fuel as supplied by J,A, Luke), O,P, Robinson (f) The Flow valuer determined from (e) wilt be used to I OIPI Roblnscn specify the type of coaxial fi Iter whf ch may be needed, to advise U, Schneider a R, Denier (g) Coadal filters, when required, will be obtained by PW from Filtrona, USA, R, Denier (h) The ignition potential aod outer temperature of designs will be borne in mind, but at this stage should not be a criteria for rejecting potential prototypes, R, Oenicr (1) Any potential biological activity of designs should be measured directly and ~ Inferred from temperature or other indirect sans, A tentative plan for screening materials is : (i) '~or the fuel, prepare the material as shredded O sheet and hand-make conventional cigarettes, Sroke and test far Anes activity land other tests if possible) Clit; PDF -!::!!::!!::!.f3 StlC.i: Dill -3- ACTION (ii) For the lerosol~generatjng material, heat for 10 minutes in a John Payne tar predictor (o~ similar device) in 101 021POZ N2 at 200' and 300'0. Collect condensate and test, R, Denier, when appt fcablC (j) The thermal eonductivlty of promising tube neteriats win be determined at BATUKE, if considered necessary from results of (d) above, This would begin In February 1989 following completion of work described in a below, R,R, Baker (Calculations by Slu~erfield indicate thermal conductivity of tube material is critical in defining temperature of inner aerosol7Jenetating material), O, For the sequential design, it was agreed that no more i R,R. Bakerl prototype designs would be considered until some basic experimental work had been done at BATUKE, I D,P, Roblnson (a) The maximum amount of nicotine elution that is possible from a tobacco-type substrate will be determined using a synthetic aerosol and materials that might potentially be used in a sequential AIRBUS design, The aerosol will be generated from one of the GREENOOT sheets and elution substrates will include high alkatoid tobaccos, extracted tobaccos and polypropy]ene filter material, A protocol will be drawn up after further discussion with R,R, 8akerlD,P, RobinsonlR.G, Hootl W. SchnoiderlW.H. Oeinerll(,G. McAdnm. ( R.R, Baker (b) Results from (a) will be supplied to B~W and BATCF on a weekly basis, and the study will be complete by 31st January 1989, K,G, Md\dam (c) PREMIER capsuler will be heated in a small furnace and the release of nicotine and other substances as a function of temperature will be determined, In addition, rpray·dried tobacco vill atra be sinilarly I pyrolysed, to assess whether nicotine etc release temperatures are the same as those in standard tobacco, Target cc~pletian: 31st January 1989. R.R, Baker (d) The temperature of the beads In PRWIER will be R,R, Baker determined during smoking, 5, Following completion of work in 3 and 4, the necessity of using CD oxidation as a source of heat will be considered, If thought appropriate, possible means of achieving this will be sought e,g, using #nOZ catalysis, R,R, Baker RP~J~· R,R, BAKER Cooies to: V,H, Oeines P,3, Dunn R, Binns R, Denter A, Porter R,R.Baker L O, Gordon 1,C,Brown O H,L.
