Kev ruaj ntseg ntawm FPV UAVs thaum lub sij hawm siab - davhlau ceev thiab kev tswj kom meej yog los ntawm ntau- kev tsim qauv ntawm lawv cov khoom, uas suav nrog aerodynamics, hluav taws xob sib raug zoo, thiab kev ntseeg tau ntawm cov qauv. Cov Cheebtsam no tsis yog cais cov koom haum tab sis theej tsim cov organic tag nrho nyob ib ncig ntawm qhov yuav tsum tau ua ntawm lub hom phiaj ntawm lub davhlau, cuam tshuam txog kev txawj ntse engineering ntawm kev sib koom tes.
Lub thav duab qauv tsim qhov tseem ceeb ntawm lub teeb yuag thiab lub zog siab. Txoj hauv kev tseem ceeb yog siv cov khoom sib xyaw carbon fiber ntau, siv lub zog axial siab thiab qhov ntom ntom ntawm cov fibers kom txo qhov hnyav thaum ua kom muaj kev cuam tshuam. Lub geometric configuration optimizes lub zog khiav txoj kev, kom ntseeg tau tias txawm load tis ntawm caj npab, nruab nrab phaj, thiab load- bearing nodes thaum hovering, acceleration, thiab tig, tiv thaiv qaug zog tsis ua hauj lwm los ntawm localized stress concentration. Tsis tas li ntawd, cov qauv tsim qauv pab txhawb kev saib xyuas thiab hloov kho dua tshiab, ua tau raws li qhov xav tau ntawm kev hloov pauv sai ntawm cov hom phiaj sib txawv.
Lub zog tsim hluav taws xob tsim tsom rau kev ua haujlwm thiab kev teb ceev. Lub cev muaj zog siv lub brushless sab nraud rotor qauv, nrog rau cov stator windings thiab hlau nplaum layout optimized los ntawm finite caij tsom xam los txo eddy tam sim no poob thiab nce torque ceev. Lub kiv cua lub aerodynamic zoo yog raws li iteration blade element txoj kev xav. Cov airfoil profile thiab pitch faib tau raug txheeb xyuas los ntawm kev ntsuas cua qhov, ua tiav qhov sib npaug ntawm qhov siab tshaj plaws thiab qhov tsawg kawg nkaus siv hluav taws xob nyob rau hauv ib qho kev ceev ceev. ESC's control algorithm integrates FOC (Field-Oriented Control) thev naus laus zis kom ua tiav- lub sij hawm thiab qhov tseeb hloov ntawm peb-theem tam sim no, kom ntseeg tau cov lus teb ntawm lub cev muaj zog thoob plaws ntau qhov kev thauj khoom.
Kev tsim ntawm kev hnov qab thiab tswj cov khoom tseem ceeb qhia txog kev hloov pauv ib puag ncig thiab kev ntseeg tau ntawm cov ntaub ntawv. Lub davhlau maub los suav nrog ntau lub sensors, suav nrog IMU, barometer, thiab magnetometer. Kalman filtering thiab lwm yam fusion algorithms suppress suab nrov thiab drift los ntawm ib tug neeg sensors, tsim ib tug ruaj khov tus cwj pwm kwv yees qauv. Lub GPS module ntiav ntau-band txais tos thiab tiv thaiv-multipath thev naus laus zis los txhim kho qhov tseeb ntawm qhov chaw nyob hauv thaj chaw nyuaj. Cov duab kis tau tus mob tsim raws li channel muaj peev xwm thiab tiv thaiv - cov hauv paus ntsiab lus cuam tshuam. RF pem hauv ntej-kawg sib koom ua ke tsis siv neeg nce tswj thiab spectrum sensing functions kom paub meej cov duab nruam thiab meej nyob rau hauv siab -ceev txav thiab electromagnetically ntom ib puag ncig.
Kev tsim cov khoom siv hluav taws xob thiab kev tiv thaiv tseem ceeb yog qhov tseem ceeb ntawm kev nyab xeeb rov ua dua thiab ua haujlwm ntev. Lub roj teeb compartment qauv ua ke nrog txhua yam kev txwv thiab cushioning pads los txo cov kev puas tsuaj rau cov roj teeb hlwb. Cov xaim xaim xaim ua raws li lub hauv paus ntsiab lus ntawm kev sib piv tam sim no nqa lub peev xwm nrog cov cua sov dissipation kom tsis txhob muaj cua sov hauv zos. Lub tshuab nqus dej poob siab siv cov ntaub ntawv viscoelastic thiab ntau-degree- ntawm- kev ywj pheej txwv kom txo qis siab- zaus vibrations qis dua qhov ntsuas qhov ntsuas siab, yog li tswj kev taw qhia thiab tswj qhov tseeb.
Zuag qhia tag nrho, cov qauv tsim ntawm FPV drone Cheebtsam yog raws li lub hom phiaj- kev taw qhia, tsim kom muaj qhov sib npaug ntawm cov qauv tsim, kev ua haujlwm siab, thiab muaj zog, thiab ua tiav kev ua haujlwm zoo los ntawm kev sib koom ua ke ntawm cov khoom. Lub tswv yim tsim qauv no yuav txuas ntxiv mus rau kev siv sib sib zog nqus ntawm FPV thev naus laus zis hauv thaj chaw xws li kev sib tw, kev soj ntsuam, thiab tshuaj xyuas.
