NASA X-57 Maxwell Era Baru Pesawat Terbang Elektrik Tahun 2018

Tinuku Info ~ NASA ingin menerbangkan pesawat terbang elektrik di udara tahun 2018. Para insinyur fokus teknologi listrik dan hibrida untuk pesawat komersial masa depan.

Mengikuti jejak program dongeng roket tahun 1940-an, insinyur NASA kini meletakkan rencana dengan sentuhan baru bagi masa depan era penerbangan bertenaga baterai. Modifikasi desain X-57 yang diusulkan didukung 14 motor listrik dan ribuan sel lithium-ion seukuran jari.

Insinyur NASA mengatakan desain baru bertenaga baterai harus berfungsi sebagai langkah pertama menuju era baru pembaharuan moda transportasi publik pesawat terbang semakin lebih hijau, lebih tenang dan lebih efisien.

"Kami bisa memperbaiki pesawat state of the art dengan mengadopsi teknologi propulsi listrik," kata Sean Clarke, peneliti utama proyek.

X-57 adalah terbaru dalam garis panjang pesawat eksperimental yang dikembangkan NASA dan pendahulunya yaitu National Advisory Committee for Aeronautics (NACA) pada tahun 1947 ketika percontohan legendaris Chuck Yeager pertama memecahkan hambatan suara di Bell X-1.

Proyek skala kecil membandingkan banyak upaya sebelumnya seperti X-30, tetapi mereka berharap dapat menelurkan solusi yang mampu diterapkan lebih umum dalam berbagai jenis pesawat. NASA juga berharap membawa teknologi baru ke pasar komersial pada tahun 2035.

"Untuk 10 tahun ke depan banyak teknologi jatuh tempo ke tingkat di mana penggunaan dalam skala penerbangan umum," kata Clarke.

Kunci terletak pada evolusi baterai. Sepertiga berat mesin ganda TECNAM P2006T terletak pada kemasan baterai. NASA bekerja sama dengan kontraktor baterai Electric Power Systems mempekerjakan 18650 sel lithium-ion komersial dengan energi spesifik sekitar 150-200 W-hr/kg.

"Kami tidak memiliki akses ke teknologi ruang mewah. Teknologi baterai ini sama seperti yang digunakan industri otomotif," kata Clarke.

Baterai menggerakkan 14 motor listrik yang dirancang dalam sayap panjang. Dua magnet motor DC sekitar 60 kW masing-masing di ujung sayap memberi propulsi pada kecepatan tinggi. Dua belas motor yang lebih kecil masing-masing 11 kW mendorong pesawat saat lepas landas, menukik dan mendarat.

Insinyur NASA bekerja dengan kontraktor swasta. Empirical Systems Aerospace berfungsi sebagai kontraktor utama, Electric Power Systems bertanggung jawab untuk baterai, Joby Aviation merancang motor dan pengendali, Scaled Composites mengintegrasi sistem listrik dan Xperimental LLC untuk sayap.

Produksi X-57 direncanakan tahun 2018. Jika kepadatan energi baterai terus meningkatkan, para insinyur berharap produsen penerbangan umum mulai menerapkan teknologi baru dalam satu dekade kemudian atau pesawat hybrid yaitu tetap menggunakan bahan bakar konvensional hanya saat lepas landas dan mendarat.

General Electric quarterly profit drops 28 percent

Tinuku - US industrial conglomerate General Electric Co reported a 28 percent drop in quarterly profit on Friday. GE confirmed its full-year EPS target adjusted from $1.00 to $1.07 per share, but cut its annual cash target to $6 billion from $6 billion to $7 billion and shares down 49 percent in the past year.

Investors are still interested in GE but many want to wait for strength and stable capital units before buying stocks. Losses widened at GE Capital to $207 million compared with a loss of $172 million a year ago. The electric unit's profit fell 58 percent in the quarter to $421 million from $ 994 million as orders fell 26 percent to $7.4 billion.


GE was the most valuable public company in the world in the past decade and a half, but has failed in some of the major industrial markets in recent years and its diversion into financial services led it into the eyes of a global financial storm in 2008. The 126-year-old company has cut costs aggressively selling the business and tr…

Masayoshi Son says Japan is stupid to disallow ride-sharing

Tinuku - SoftBank Group Corp CEO Masayoshi Son blasted Japan on Thursday for not allowing ride-sharing services, calling it “stupid” and saying the country was lagging overseas rivals in areas such as artificial intelligence (AI). Son has also been highly critical of the government previously when SoftBank was still a fledgling telecoms service trying to break up a cosy duopoly in Japan.

The comments reflect Son’s frustration with Japan where he built SoftBank’s domestic telecoms business, the cash engine that has powered his investments. The group has, however, focused its growing range of technology investments overseas. Japan outlaws non-professional drivers from transporting paying customers on safety grounds and the country’s taxi industry lobby has vigorously opposed deregulation.


“Ride-sharing is prohibited by law in Japan. I can’t believe there is still such a stupid country. A country that gives up on the future has no future,” Son said at an annual company event aimed at cus…

Hyundai Mobis increases AI scale to spur efficiency

Tinuku - Hyundai Mobis, the auto parts making unit of Hyundai Motor Group, implemented artificial intelligence to its software screening process and document search system for improved efficiency and accuracy. The company said Sunday The move came in line with the latest efforts to shift into a software-centered company and to diversify the use of AI in research and development.

The AI-based software screening system, dubbed Mobis Artificial Intelligence Software Testing, jointly made with a professor of South Korea’s top science and technology university KAIST, will screen new software based on algorithm made by researchers. By automating the process, Hyundai Mobis expects to enhance work efficiency, shortening the time it takes to develop software while improving accuracy.


“With MAIST replacing 50-70 percent of researchers’ workload, they are now able to work in a creative environment, focus on speeding up software creation and boost capabilities in algorithm development,” Hyundai M…

Wipro increased Q1 net profit up 11% to $307.55 million

Tinuku - Wipro’s first-quarter net profit rises 11% to $307.55 million from $277 million in the preceding three months. Wipro Ltd on Friday reported first-quarter earnings that beat analysts expectations, primarily on account of gains made from divestment of one of its businesses.

India’s third biggest software services exporter guided for revenue to grow at best 2.3% in the current quarter, leading some analysts to believe that while Wipro’s sequential growth is improving, it is still far from turning the corner.


Bengaluru-based Wipro’s dollar revenue declined 1.7% (improved 0.1% in constant currency terms) to $2.03 billion in the quarter ended 30 June from the preceding three months, after it had earlier outlined quarterly growth of at best 0.2% in constant currency terms. Wipro, which gives only quarterly growth outlook, expects to grow its revenue between 0.3% and 2.3% in constant currency terms in the July-September period from the preceding quarter.

“I’m happy with our performan…
