KOLLEKTIIVISELLA IONIKIIHDYTTIMELLA TOIMIVA TYONTOVOIMALAITECOLLECTIVE ION ACCELERATOR PROPULSION
Keksinndn kohteena on lahinna avaruusaluksiin ja lentokonei-siin soveltuva sahkoinen tydntdvoimalaite ja sen teholShde. Tydntdvoiman aikaansaanti avaruudessa perustuu Newtonin kol-menteen lakiin, F = ma, jossa m on mukana kuljetettava ulos-heitettSvS massa ja a sen kiihtyvyys.The present invention relates to an electric auxiliary power plant suitable for spacecraft and aircraft and its power supply. The generation of the full force in space is based on Newton's third law, F = ma, where m is the mass to be carried out and the acceleration.
Suuren massan kuljettaminen mukana rajoittaa suuresti avaruus-aluksen suorituskykyS ja matkan pituutta, joka ilmenee liike-mSSrien sSilyttkmisen laista, joka pStee kaikenlaisi1le rake-teille tai vastaaville Mr * vr = Mp * vp, jossa aluksen lii-kemSSrS on yhtSldn vasemmalla puolella ja ulosheitettSvSn ajoaineen liikemSara oikealla puolella. Siis jos ajoaineen massalle Mp saadaan suuri nopeus vp, niin tietyn aluksen liikemaSrSn kehittSmiseen tarvitaan våhemmån ajoainetta. Kemiallisilla rakettimoottoreilla ajoaineen purkautumisno-peudet ovat luokkaa 4...5 km/s. ja kehittyneilIS ionirake-teilla jopa 1000 km/s.Carrying large masses greatly limits the spacecraft's performance and distance, as evidenced by the law of the retention of motion masses, which applies to all kinds of granules or the like Mr * vr = Mp * vp, where the ship's propulsion is on the left side of the coil and the effluent movementSara on the right. Thus, if a high velocity vp is obtained for the mass Mp of the propellant, then less propellant is needed to develop the motion of a given ship. With chemical rocket engines, the release rates of the propellant are of the order of 4 ... 5 km / s. and with advanced IIS granules up to 1000 km / s.
Toisaalta ionimoottorin suuri purkautumisnopeus ja tyontdvoima merkitsevSt suurta tehontarvetta ja mutta ei valttSmSttS suurta energiaa, jos moottori toimii sysSysperiaatteella. Kehittyneen ionimoottorin suuri sahkdtehontarve voidaan tyydyttaa ydinreak-torin tai suljetun plasma MHD-generaattorin avulla.On the other hand, the high discharge rate and work force of the ion motor mean a high power requirement and but not a large amount of energy if the motor operates on the sysSys principle. The high electrical power demand of an advanced ion engine can be met by a nuclear reactor or a closed plasma MHD generator.
Monissa aikaisemmin esitetyissS ionimoottorikeksinndissS kuten seuraavissa patenteissa: EP 0132065, PCT WO 88/08488, DE 2052014, DE 3728011 ja US 3956666 ionien kiihdytys perustuu nk. tavan-omaiseen ionimoottoriin, jossa suoraan kiihdytetaan ioneja suh-teellisen pienellS sahkokentSn voimakkuudella, jolloin rajoitta-vana tekijana on nk. lapilyontijSnnite Ug - 100 kV, jota rajoittaa avaruusvaraus ja tehollinen ionivirta I jSS pieneksi (mA-luokka) sekS tydntdvoima F < 1 N. (F = 2 UI/vp). Kuva 1.In many previously disclosed ion engine inventions, such as the following patents: EP 0132065, PCT WO 88/08488, DE 2052014, DE 3728011 and US 3956666, the acceleration of ions is based on a so-called conventional ion motor in which ions are directly accelerated with a relatively small electric field. the factor is the so-called lapilyontier voltage Ug - 100 kV, which is limited by the space charge and the effective ion current I jSS low (mA class) and the filling force F <1 N. (F = 2 UI / vp). Figure 1.
TSllaista pienitehoista moottoria voidaan kSyttSa lahinnS satel-liittien ratakorjauksiin, joissa tydntdvoimatarve on satojen mN:n luokkaa. (esim. UK-10 ja UK-25, jotka ovat Kaufman-tyyppisia ionimoottoreita).Such a low-power motor can be used mainly for track repairs of satellite connections, where the total power requirement is in the order of hundreds of mN. (e.g. UK-10 and UK-25, which are Kaufman-type ion engines).
2 NSistS syistS johtuen olen keksinyt uuden tavan kehittaa suuria tyOntdvoimia sMhkdisin menetelmin pienelia ajoainesydtdlia, johon liittyy myoskin tarvittava tehoiahde suljettu plasma MHD-generaat-tori.2 NSistS due syistS I have invented a new method to generate large tyOntdvoimia sMhkdisin methods for a small ajoainesydtdlia, involving also the required tehoiahde closed Plasma MHD generator-rotor.
Keksintdni perustuu ydinfysiikassa kaytettavaan kollektiiviseen ionikiihdyttimeen, jolla ionimassa voidaan kiihdyttåa erittåin suu-riin nopeuksiin (n. 0,01 c) suur-sahk6kenttaemissiota (n. 10^ V/m) hyvaksikayttaen, jolloin kehittyy suuri tyontovoima pienelia ajoai-nesyQtdlia (F = mp * Vp), jota tarvitaan esim. aluksen noustessa planeetan pinnalta. Kuva 3. Periaatteessa voidaan kehittaa tarvit-tavan suuria tydntovoimia jos sahkdtehoa on riittavasti kaytetta-vissa.The invention is based on a collective ion accelerator used in nuclear physics, with which the ion mass can be accelerated to very high velocities (approx. 0.01 c) by utilizing a large electric field emission (approx. 10 ^ V / m), thereby developing a large working force with a small driving force. * Vp), which is needed, for example, when a ship rises from the surface of the planet. Figure 3. In principle, the required high filling forces can be developed if sufficient electric power is available.
Kollektiivisella ionikiihdyttimella voidaan synnyttaå suurivirtai-sia ionipulsseja, joiden energia on muutama MeV/ydin ja huippuvirrat 1... 100 kA. Purkautuvat hiukkaset voivat olla ionisoituneita atomeja, molekyylejM, p51yM, varattuja kolloidisia hiukkasia tai nestepisaroita.With a collective ion accelerator, high-current ion pulses with an energy of a few MeV / core and peak currents of 1 ... 100 kA can be generated. The discharged particles can be ionized atoms, molecules, p51yM, charged colloidal particles or liquid droplets.
Tailaista kollektiivista kiihdytinta voidaan kayttaa suurivir-taisena ioniiahteena ja ionimoottorina avaruusaluksissa, lento-koneissa, veneissa, laivoissa, autoissa yms. seka mm. plasma magnetohydrodynaamisen (MHD-) generaattorin ioniiahteena.Such a collective accelerator can be used as a high-current ion source and ion engine in spacecraft, aircraft, boats, ships, cars, etc., as well as e.g. plasma as an ion source of a magnetohydrodynamic (MHD-) generator.
Tailainen kulkuneuvo on erittåin ympåristoyståvallinen.Such a vehicle is very environmentally friendly.

E is the intensity of the electricity. The negative potential line (dashed line) moves with the ion beam and acts as an accelerator tMvMna electrode or virtual cathode for the positive ions. Figure 5 shows one possible application for the invention: a spacecraft or similar filling power unit.
Kuva 6 on yksinkertaistettu kaavio suurjannite pulssigeneraattorista, joka toimii IREB diodin ja ionisuihkun suuritehoisena sahkdiah-teena, jossa T on GTO tai vastaava kytkin, D on energian palautus-diodi, C:t ovat kondensaattoreita, L:t ovat induktansseja ja M on kaksoisresonanssi pulssimuuntaja.Figure 6 is a simplified diagram of a high voltage pulse generator operating as a high power electrical diachide of an IREB diode and an ion beam, where T is a GTO or similar switch, D is an energy recovery diode, C is a capacitor, L is an inductance and M is a double resonance .
Kollektiivinen ionikiihdytin perustuu kylmakatodiputkeen, jossa katodin ja anodin vaiinen hyvin suuri hetkellinen tasajannite tekee anodin positiiviseksi katodin suhteen. Katodin muodostaa hyvin tera- · va piikki tai putki tai joukko niita. N3in siksi, etta saataisiin hyvin suuri sahkdkentan voimakkuus katodin ja anodin vaiille, luok-kaa 1 MV/mm. Taildin saadaan aikaan elektroniemissio kylmaita kato-dilta, joka noudattaa Fowler-Nodheimin virrantiheyslakia.The collective ion accelerator is based on a cold cathode tube, where a very large instantaneous direct voltage of the cathode and the anode makes the anode positive with respect to the cathode. The cathode is formed by a very sharp spike or tube or a series of them. N3in, in order to obtain a very high electric field strength for the cathode and anode silicon, is of the order of 1 MV / mm. Taild provides electron emission from a cold cathode that complies with the Fowler-Nodheim current density law.
Tata nimitetaan kenttaemissioksi tai kylmakatodiemissioksi.Tata is called field emission or cold cathode emission.
Jos anodin ja katodin vaiimatka diodissa on 12 mm ja anodiaukon hal-kaisija 25 mm, tarvitaan vahintaan miljoonan voltin eli 1 MV kiihdy-tysjannite kenttåemission aikaansaamiseksi, jolloin elektronivirta voi olla luokkaa 30 kA ja elektronisuihkun nopeus lahelia valon no-peutta. T3sta johtuen puhutaan intensiivisesta relativistisestiseen nopeuteen kiihdytetysta elektronisuihkusta eli lyhenteena IREB. Tarvittava lyhytkestoinen kiihdytysjannite on parasta kehittaa suuri-tehoisella kevyelia ilmasydåmiselia suurjannite pulssimuuntajalla tai vastaavalla, jota sydtetaan kytkinlaitteen avulla matalammasta tasajannitteesta, joka saadaan esim. suljetusta plasma MHD-generaat-torista. Kun anodin sisapuolelle nk. tyhj^jvaellusputkeen lahelle anodiaukkoa johdetaan puhallusventtiilin kautta esim. kaasusuihku, niin syntyy voimakas kaasun sisåysionisaatio, kun IREB iskee kaasu-pilveen ja elektronien muodostaman varauspilven voimakkaan sahkdkentan E n 100... 500 MV/m johdosta ionijoukko kiihtyy hyvin suureen nopeuteen ja kehittaa reaktiovoiman Newtonin lain mukaan.If the anode and cathode pitch in the diode is 12 mm and the anode aperture diameter is 25 mm, an acceleration voltage of at least one million volts, or 1 MV, is required to achieve field emission, whereby the electron current can be on the order of 30 kA and the electron beam speed close to light. Due to T3, we speak of an intensive electron beam accelerated to a relativistic speed, or IREB for short. The required short-term acceleration voltage is best developed with a high-power light air-core high-voltage pulse transformer or the like, which is energized by a switching device from a lower DC voltage obtained, e.g., from a closed plasma MHD generator. When a gas jet is led to the inside of the anode inside the so-called vacuum hose near the anode opening, e.g. a gas jet, strong internal ionization of the gas occurs when the IREB strikes the gas cloud and the electron charge cloud due to the large electric field E n 100 ... 500 MV / m speed and develop a reaction force according to Newton’s law.
Tatå nimitetaan kollektiiviseksi ionien kiihdyttimeksi, positiivis-ten ionien virran ollessa jopa kA-luokkaa. Ionimoottorin tydntovoi-man F riippuessa suihkun tehosta P ja nopeudesta vp: F = 2P/vp.Tatå is called a collective ion accelerator, with a positive ion current of up to the kA order. With the full force F of the ion motor depending on the power P and the speed vp: F = 2P / vp.

Lasketaan esimerkiksi tapaus, etta ionisoitavana ajokaasuna kSytetaan neonia, Ne, jonka suhteellinen atomipaino on n.20 ja ionin massa m^= 33,4* 10~24 g. jos ionisuihkun virta on 3 kA, niin ionien lukumSara on Ni = 1,87* 1022 /s ja suihkun massa/s = ms = 0,62 g/s. Jos kiihdytysjannite on U= 1MV, niin tybntdvoimaksi saadaan: F = (2 mp P)1/2 * (2* 6,2*10-2* 3*109)!/2 N = 1930 N Tålldin ainesuihkun nopeus on n. 0,01 cCalculate, for example, the case that neon, Ne, having a relative atomic weight of n.20 and an ionic mass m ^ = 33.4 * 10 ~ 24 g is used as the ionizable propellant. if the ion beam current is 3 kA, then the number of ions is Ni = 1.87 * 1022 / s and the jet mass / s = ms = 0.62 g / s. If the acceleration voltage is U = 1MV, then the tybntd force is: F = (2 mp P) 1/2 * (2 * 6.2 * 10-2 * 3 * 109)! / 2 N = 1930 N The speed of the material jet in Tåld is n. 0.01 c
Suurta kiihdytysjånnitettå kaytettMessa pyrittSessa suureen tyQntdvoimaan on edullista kåyttSS sellaista ajoainetta, jonka molekyylipaino on mahdollisemman suuri kuten esim. polyeteenillå.When using high acceleration stress in order to achieve a high working force, it is advantageous to use a propellant with the highest possible molecular weight, such as polyethylene.
Jotta avaruusalus ei varautuisi sShkdllS, tulee ionisuihku pystyå neutraloimaan melko lyhyellå matkalla. Jos kiihdytys-elektrodien vSli on s, niin neutraloinnin tulisi tapahtua viimeistaån 2s VT* etaisyy^ella kiihdytyselektrodin tai vas-taavan jSlkeen. Virtuaalisen katodin tulisi muodostua ennen 2s etSisyytta, jolloin muodostuu tasapainotilanne ja positiivisia ja negatiivisia varauksia on yhtåpaljon ja muodostuu plasma-alue. Tama saavutetaan, kun positiivisten ionien tuotanto on riittavS synnyttamaSn potentiaalimaksimin. Kollektiivisessa kiihdyttimessa molempia ajoaineen mSarSS ja elektronisuihku-virtaa voidaan saadelia ja saavuttaa lShes neutraali ainesuih-ku.In order for the spacecraft not to be charged with sShkdllS, the ion jet must be able to neutralize in a fairly short distance. If the vSli of the acceleration electrodes is s, then the neutralization should take place at the latest 2 s VT * away from the acceleration electrode or the like. The virtual cathode should be formed before the 2s etSity, in which case an equilibrium situation is formed and there are equal amounts of positive and negative charges and a plasma region is formed. This is achieved when the production of positive ions is sufficient to generate the maximum potential. In a collective accelerator, both the mSarSS and electron beam currents of the propellant can be obtained and a neutral material jet can be achieved.
