Pecco Bagnaia catat masa terpantas 1:56.682

Hari ke-3 Ujian Rasmi MotoGP™ Sepang 2024 mencatatkan ‘lap’ terpantas 1 minit 56 saat di Litar Antarabangsa Petronas Sepang oleh penyandang juara dunia MotoGP™ Francesco Bagnaia. Diikuti dengan Jorge Martin, Enea Bastianini dan juga Alex Marquez yang masih menunggang jentera lama GP23.

Rekod catatan masa terbaru ini menunjukkan bahawa teknologi hari ini tidak tertumpu pada enjin semata-mata. Aerodinamik juga memainkan peranan yang penting walaupun dengan hanya sebutir ‘winglet’ yang kecil dapat menbantu memperbaiki catatan masa.

Dengan keadaan litar yang semakin panas, kebanyakan pelumba kembali ke litar dengan tayar yang sudah digunakan. Mereka melakukan beberapa simulasi untuk mengumpul data sebanyak mungkin.

Hari terakhir ujian di Sepang ini memperlihatkan pengilang Jepun masih tercari-cari jawapan yang mereka harapkan. Walaupun Honda dan Yamaha telah membuat peningkatan yang besar, masih terdapat kelemahan tertentu  untuk menghasilkan masa terbaik.

Musim ini Pol Espargaró terpaksa melepaskan tempatnya untuk Pedro Acosta. Pol memikul tugas yang sama seperti Pedrosa sebagai penunggang uji KTM. Sementara itu, adiknya Alex Espargaró seperti berminat dengan dunia penyiaran. Pelumba Sepanyol itu beraksi sebagai hos memperkenalkan pit KTM kepada penonton. Good Luck, Pol !!!

Aero Rakes di MotoGP – Part 2

Sambungan penjelasan tentang Aero Rakes dari Dr. Aid Fawzal semalam, rakan beliau, Nik Muhammad Nasri, manambah penerangan dengan lebih terperinci. Nik Muhammad Nasri merupakan seorang jurutera ‘wind tunnel’ yang kini bertugas di Coventry University, UK.

Sensor yg digunakan pada Aero Rakes di MotoGP tu ialah Kiel Probes. Measurement of method masih sama, menggunakan pressure sensor untuk ukur perbezaan tekanan (pressure) antara stagnation point dengan static point. Hasil dari perbezaan pressure ini, kita dapat tahu total pressure dekat point of measurement. Dari pressure, kita boleh mengira kelajuan angin menggunakan formula p=(mV₂)/2.

Perbezaan Kiel Probes dengan Pitot Tube ialah Kiel Probes mempunyai penghadang (shroud) dekat tip untuk menyukat ‘stagnation pressure’. Ini bermaksud sukatan Kiel Probes lebih ‘localised in a sense of directionality’. Dengan kata lain, result ‘measurement’ Kiel Probes kurang sensitif dengan perubahan ‘Yaw angle’.

Aero Rakes di MotoGP?

Alamak tuan, dah kenapa MotoGP bawak raga kat belakang motor pula ni??

Itu bukan raga ya, jaring pon bukan. Itu adalah “aerodynamics rakes” (juga dipanggil “aero rakes”).

Guna aero rakes ni adalah untuk mendapatkan bacaan tekanan dinamik (dynamic pressure) supaya jurutera dan jurureka (designer) mendapat gambaran bagaimana struktur aliran angin dibahagian tersebut.

Dalam gambar tu aero rakes diletakkan di hujung belakang, maksudnya ujian sedang dijalankan untuk mengenalpasti aliran angin di belakang. Ini mengambil kira kedudukan pelumba yang berubah² dan prestasi komponen aerodinamik sedia ada.

Data yang aero rake ni rekodkan juga akan membantu jurutera dalam menentusahkan dan memperbaiki program simulasi Computation Fluid Dynamics (CFD) yang mereka jalankan.

Untuk penjelasan ringkas, simulasi CFD terhad kepada satu² senario kedudukan motorsikal (cth: simulasi sewaktu tegak-lurus, atau simulasi konar-baring). Kata kan sudut-condong (lean angle) maksimum 60°, setiap 5° baringan akan dibuat simulasi satu-persatu.

Begitu juga dengan dapatan (results) daripada ujian terowong angin (wind tunnel). Ia terhad kerana angin yang datang sentiasa daripada depan dan bukan angin senget seperti sewaktu mengambil selekoh (cornering).

Kerana itulah, data langsung daripada lapangan sangat² diperlukan dan implementasi “aero rakes” ini lah antara cara mendapatkan datanya. Data yang diambil pastinya lebih dinamik berbanding CFD dan terowong angin kerana ia mengambil kira semua pergerakan motorsikal dan pergerakan pelumba dengan dinisbahkan terhadap keadaan litar.

Pakar dalam bidang ini dipanggil trackside aerodynamicist.

ANOTHER RACE WIN FOR HAYDEN HAIKAL

A third race win and a 6th placing in last weekend’s Round 2 of Idemitsu Super Turbo Championship in Thailand (19-21 May) at the Chang International Circuit in Buriram has consolidated Malaysian teenager Hayden Haikal’s lead in the overall point standings.

With three wins in four races so far, Hayden and the #437 Wing Hin Motorsports’ Toyota Vios continued to exert their dominance in the Junior (Normally Aspirated) Class for normally-aspirated engines up to 1550cc and remains one the top overall race contenders in a sea of turbocharged and more powerful cars.

The race weekend however, could not have gotten off to a more challenging start for 18-year-old Hayden. A big off during the free practice session on Friday had the team working in overdrive with only three hours to complete repairs in time for the qualifying session. Hayden and the team bounced back to still post the third fastest time in Class.

Race 1 on Saturday got off to a promising start with Hayden fighting for the lead in his Class and running as high as 12th overall until transmission issues half way into the race left him with only 5th gear and fighting to get to the finish. He ended the 12-lap race around the 4.554km Chang International Circuit 21st overall and 6 th in class.

“I had a good fight with the Class leader and I managed to get away from him when all of a sudden the car wouldn’t downshift from 5th gear. Thankfully, we managed to resolve the problem for the second race on Sunday,” said Hayden.

Race 2 on Sunday proved to be the great redeemer when Hayden’s pace had him at the head of his Class and placed 8th overall amidst the professional and turbocharged drivers. Hayden finished 2nd in Class but was later promoted to first when the race winner was penalized for an infringement.

“The start of the race was chaotic with a lot of cars being taken out on the main straight. I was fortunate I managed to avoid the carnage and get through safely before the red flag was brought out. When the race resumed I was battling with the top three cars in my Class and it then came down to the task of picking them out one at a time,” said Hayden.

Making his debut in the Idemitsu Super Turbo Championship in March, Hayden had sealed back to back race victories in the opening two races of the Idemitsu Super Turbo Championship.

With three race wins and a 6th placing after four races, Hayden retains his lead in the overall point standings in the Junior (Normally Aspirated) Class with the third and final round of the Idemitsu Super Turbo Championship to be contested from 16-18 June 2023 again at the Chang International Circuit.

“We will be regrouping and with this weekend’s experience and learnings, the focus will now be on going for the overall championship win.”
