Para insinyur telah bekerja banyak, terutama pada aerodinamika, kata bintang KTM MotoGP Pol Espargaro baru-baru ini.

Selama pramusim, fairing RC16 Espargaro tidak hanya menampilkan beberapa gaya gigi gergaji dan bagian sayap yang melengkung secara rumit, tetapi, setidaknya untuk bagian pengujian, dilengkapi dengan Gurney Flaps.

Sebuah Gurney Flap - dinamai sesuai 'penemuan' mereka oleh tim legenda balap mobil Dan Gurney di tahun 1970-an - terdiri dari 'tab' kecil, mengarah ke atas secara vertikal, melintasi tepi belakang sayap.

Meskipun penampilannya yang tumpul menunjukkan bahwa itu akan mengurangi kinerja aerodinamis, perubahan tekanan yang diciptakan oleh Flap membantu mencegah 'lapisan batas' udara (terdekat dengan sayap) terlepas dari permukaan, sehingga meningkatkan gaya turun meskipun terkadang dengan mengorbankan tarikan ekstra.

Menurut cerita rakyat balap, Gurney awalnya mencoba menyembunyikan tujuan sebenarnya dari perangkat tersebut dengan mengatakan itu hanya untuk menghindari pemotongan tangan mekanik saat mendorong mobil ...

Gambar-gambar ini menunjukkan fairing KTM pabrik Espargaro yang dilengkapi dengan dan tanpa Gurney Flaps selama tes pembukaan 2020 di Sepang.

Dengan Gurney Flaps:

Pada saat tes pramusim MotoGP terakhir di Qatar, ketika fairing dalam warna Red Bull penuh, tampaknya Espargaro telah memilih Flaps yang dipasang hanya pada permukaan sayap bagian bawah (internal) dan bukan atas:

Namun, rekan setim rookie Brad Binder, ditambah Miguel Oliveira dan Iker Lecuona dari Tech3 tampaknya tidak memiliki Gurney Flaps di mesin mereka (meskipun jangka pendek selalu memungkinkan).

Sampai balapan pembukaan diadakan, masih harus dilihat apakah ada Gurney Flaps yang dimasukkan dalam desain fairing 'dihomologasi secara digital' oleh KTM untuk para pebalapnya di awal musim ini.

Tim kemudian diizinkan untuk membuat satu pembaruan desain fairing lebih lanjut sebelum akhir kejuaraan dunia.

Tampaknya tidak ada tim lain yang menjalankan Gurney Flaps selama pengujian pramusim 2020, meskipun sebagai metode penyetelan aerodinamis yang terkenal, akan mengejutkan jika mereka tidak diadili secara tertutup pada tahap tertentu.
