MotoGP Spy a Sepang: il nuovo Aero-pack della Yamaha M1

Nel test MotoGP di Sepang Yamaha sta lavorando su un nuovo pacchetto aerodinamico per la YZR-M1. L’obiettivo è acquistare top speed non solo con il motore.

di Paul Emile Viel

Yamaha ha debuttato con un nuovo pacchetto aerodinamico allo shakedown che ha preceduto i test MotoGP a Sepang. La filosofia generale è in gran parte simile a quanto già visto in pista. Ma l’aletta principale è molto più piatta e dirige il flusso d’aria anche davanti alla presa d’aria, che non è da meno rispetto  a quella dell’Aprilia RS-GP.

A Jerez, durante i test di fine anno, gli ingegneri Yamaha avevano già apportato modifiche al loro pacchetto aerodinamico, ma a Sepang queste sono molto più radicali.

Ecco la carena testata a Jerez, dove l’area che si è evoluta è appena sopra le pinne aerodinamiche. Sulla carena attuale, in questa stessa zona, la carena ha una piccola sezione concava che gira verso l’interno. Su questa nuova versione è molto più liscia e arrotondata.

Ecco la versione che è stata provata a Sepang dal collaudatore Kohta Nozane, durante la seconda giornata dello Shakedown. Con questa pinna principale più grande della precedente, l’obiettivo della Yamaha sembra essere quello di cercare di massimizzare il carico aerodinamico sulla ruota anteriore. Inoltre, passando sotto la presa d’aria, massimizza anche il flusso d’aria in entrata nell’air box, limitando le turbolenze in modo da favorire la potenza e la coppia del motore Yamaha, notoriamente in deficit rispetto ai suoi concorrenti.

U.S. dollar holds steady before the release of U.S. non-agricultural employment report

路透纽约10月7日 - 美元兑一篮子货币周四持稳,周五将公布的美国劳动力市场数据可能为美国联邦储备委员会(美联储/FED)下一步行动的时机提供线索。大多数主要货币对陷于近期区间内交投,交易员不愿在数据公布前大举押注。支付公司Caxton的高级分析师Michael Brown表示:“今天的市场是相当典型的非农就业数据公布前的沉闷。”美元指数持平于94.199,距离上周触及的一年高位94.504不远。Brown称,“我认为,在就业报告出炉之前,我们可能会一直像这样陷于区间,但即便到那时,考虑到11月缩减量化宽松看起来近乎确定,美元的任何疲势都应该会消退。”随着从大流行危机政策转变的势头增强,美联储已表示,可能最早在11月开始减少每月的债券购买,之后将加息。路透调查显示,将于周五公布的非农就业数据预计将显示劳动力市场持续改善,9月料新增45.5万个就业岗位。“美国稳步改善的劳动力市场和稳健的经济增长应该会为美联储开始缩减量化宽松计划开绿灯。”瑞银全球财富管理首席投资官Mark Haefele在一份报告中表示。美国银行全球研究的外汇策略师在一份报告中表示,在非农就业报告公布后的一周,美元往往会扭转自报告发布当天以来的大部分涨幅或跌幅。美国上周初请失业金人数有所下降,但9月裁员人数从24年低位回升,部分原因是医院解雇未接种疫苗的员工,以及缺乏工人迫使一些设施关闭。英镑上涨0.3%,因全球风险情绪略有改善,分析师表示,英国央行加息的前景降低了英镑的一些下行潜力。比特币从周三触及的近五个月高位55,800美元回落,盘尾报约54,040.48美元。(完)for-phone-onlyfor-tablet-portrait-upfor-tablet-landscape-upfor-desktop-upfor-wide-desktop-up
