hom phugoid feem ntau yog maj mam damped low-frequency oscillation hauv nrawm u, uas khub niam txiv mus rau hauv tus cwj pwm θ thiab qhov siab h. … Yog li lub phugoid yog classical damped harmonic motion uas ua rau lub dav hlau ya ib maj mam sinusoidal ya davhlau txoj kev hais txog lub nominal trimmed qhov siab datum.
Yuav ua li cas dampen phugoid motion?
Ib qho chaw ruaj khov, txo qis phugoid tuaj yeem ua tiav los ntawm kev tsim lub me me stabilizer ntawm tus Tsov tus tw ntev dua, lossis, ntawm tus nqi ntawm lub suab thiab yaw "static" stability, los ntawm kev hloov cov nruab nrab ntawm lub ntiajteb txawj nqus mus rau nram qab.
Yuav ua li cas yog yob txoj kev?
Roll subsidence hom yog tsuas yog qhov damping ntawm rolling motion. Tsis muaj lub sijhawm aerodynamic ncaj qha tsim los ncaj qha rov qab tis-theem, piv txwv li tsis muaj rov qab "caij nplooj ntoos hlav quab yuam / lub sijhawm" proportional rau yob lub kaum sab xis.
Dab tsi yog yam cuam tshuam rau lub sijhawm thiab kev ua kom lub zog oscillations?
Qhov tseem ceeb tshaj plaws, lub sijhawm oscillation yog ncaj qha proportional rau caj npab 'ntev. Ntxiv mus, lub sij hawm ntawm oscillation yog inversely proportional rau lub ntiajteb txawj nqus. Kev nce ntawm pendulum caj npab ntev ua rau muaj kev nce ntxiv hauv lub sijhawm. Tsis tas li, qhov kev ncua ntev ua rau txo qis hauv lub sijhawm.
Yuav ua li cas cuam tshuam txog kev ruaj ntseg ntev?
Qhov kev ruaj ntseg ntev ntev ntawm lub dav hlau tau cuam tshuam los ntawm qhov kev ncua deb (lub sijhawm caj npab lossis caj npab npab)nruab nrab ntawm qhov nruab nrab ntawm lub ntiajteb txawj nqus (c.g.) thiab qhov chaw aerodynamic ntawm lub dav hlau. Cov c.g. yog tsim los ntawm tus tsim ntawm lub dav hlau thiab cuam tshuam los ntawm nws cov loading, raws li los ntawm payload, neeg nrog caij, thiab lwm yam.

Puas yog brownian motion markovian?
Brownian tsab ntawv tsa suab nyob hauv kev sib tshuam ntawm ob peb yam tseem ceeb ntawm cov txheej txheem. Nws yog a Gaussian Markov txheej txheem, nws muaj txoj hauv kev txuas mus ntxiv, nws yog txheej txheem nrog kev ywj pheej nce ntxiv (tus txheej txheem Lévy), thiab nws yog martingale.
Nyob rau hauv damped harmonic motion?
Damped harmonic motion is a tiag oscillation, uas ib yam khoom yog dai rau ntawm lub caij nplooj ntoos hlav. Vim tias muaj kev sib txhuam sab hauv thiab huab cua tsis kam, lub kaw lus yuav dhau sijhawm dhau los ntawm kev txo qis hauv amplitude.
Phugoid motion yog dab tsi?
A phugoid lossis fugoid /ˈfjuːɡɔɪd/ is ib lub dav hlau txav uas lub tsheb nce thiab nce, thiab tom qab ntawd pitches thiab nqis, nrog rau kev nrawm thiab qeeb raws li nws mus "downhill" thiab "uphill". Phugoid oscillation yog dab tsi?
Nyob rau hauv lub ntiaj teb motion lub cheeb tsam tshaj tawm?
Nyob rau hauv lub ntiajteb txawj nqus, qhov chaw tshaj tawm ntawm txoj hauj lwm vector ntawm lub ntiaj chaw depends on angular velocity (ω) and distance (r) of the planet from the sun. Lub cheeb tsam ntawm lub ntiaj teb yog dab tsi? Lub tswv yim ntawm thaj chaw nrawm yog txuas nrog keeb kwm zoo nrog lub tswv yim ntawm lub nrawm nrawm.
Dab tsi yog stroboscopic motion hauv kev puas siab puas ntsws?
qhov pom tseeb tsis muaj zog lossis thim rov qab ntawm cov khoom txav, xws li lub kiv cua tig, tsim los ntawm kev teeb pom kev zoo nrog lub teeb ci ntsa iab. Kuj hu ua stroboscopic effect. See also windmill illusion. Dab tsi yog stroboscopic motion?
