Easy Empty Dust Cup: Silent Hawk dan Nightmare, 2 Motor Senyap Militer AS TEMPO.CO, Washington D.C. - Lembaga riset Departemen Pertahanan Amerika, DARPA, memiliki dua proyek sepeda motor siluman generasi mendatang. Silent Hawk, yang diproduksi Logos dan Nightmare dari LSA Autonomy, adalah dua proyek yang didanai oleh lembaga tersebut.

Dua prototipe motor itu telah diperlihatkan di dalam Konferensi Industri Pasukan Operasi Khusus dari Asosiasi Industri Pertahanan Nasional di Tampa baru-baru ini. Kedua sepeda motor memiliki fitur mesin hybrid multi-bahan bakar yang dapat menggunakan berbagai jenis bahan bakar, mulai dari bensin jet hingga minyak zaitun. Alex Dzwill, insinyur dari Logos, mengatakan kepada Defence One, bahwa sepeda motor itu memiliki dua mode, satu mode suara keras, dan satu mode suara senyap untuk beroperasi menggunakan sebuah baterai. Mode suara keras menghasilkan intensitas bunyi 80 desibel, sedangkan modus tenang menghasilkan 55 desibel. Untuk operasi normal, sepeda motor itu akan menggunakan diesel, bensin atau bahan bakar jet. Tapi ketika dekat dengan musuh, motor itu akan berjalan hampir tanpa suara menggunakan listrik. Menurut pembuatnya, Logos Technologies, mode keras akan sedikit lebih keras daripada rata-rata vacuum cleaner, mencapai hingga 75 desibel. Perusahaan juga mengatakan Silent Hawk dapat bepergian di medan yang sulit pada mesin hibrida pada kecepatan 55 mil per jam (88km/jam).

Mesin pembakaran juga dapat dilepas, yang berarti Silent Hawk dapat sepenuhnya menggunakan listrik. Baterai sepeda motor dapat mendukung hingga 50 mil (80km). Namun, konsep ini masih dalam pengembangan dan spesifikasi lebih lanjut belum diumumkan. DARPA memulai proyek sepeda motor ini tahun lalu, dan kini telah meminta pembuatnya untuk mengembangkan lebih lanjut. Logo mengatakan saat ini pihaknya berencana untuk melanjutkan dengan rencana program Tahap II, dengan tujuan mengembangkan dan menguji prototipe operasional pertama dalam 18 bulan.vacuum cleaner hitachi cv-sh18Silent Hawk berbasis motor balap listrik Alta Motors, RedShift MX. sanyo transformax 3 in 1 vacuum cleaner bagsIa menggunakan rangka Alta, sementara mesin hybrid dikembangkan oleh Logos. eureka 96dz lightweight cordless vacuum cleaner

Komando Operasi Khusus AS sebelumnya mencoba menggunakan sepeda motor Zero MMX untuk tujuan yang sama, namun baterainya hanya bertahan dua jam.Bukan hanya komando yang akan menerima sepeda motor ini. Pada bulan Agustus, pasukan polisi bakal menggunakan sepeda motor ini untuk mendekati penjahat agar tidak terdeteksi. Motor itu, yang dirancang oleh Zero Motorcycles di California utara, memiliki kecepatan tertinggi hingga 98 mph (158 km/jam), yang memungkinkan polisi untuk mengejar penjahat jika pendekatan siluman gagal.

I was gently corrected about this on more than one occasion. Noise is what the HALOsonic car eliminates, sound is what it creates. A technology demonstrator beneath the bodyshell of a Toyota Prius, the HALOsonic showcases innovative British engineering that makes a four-cylinder engine sound like a V6, V8 or V12. Want to hum like a spaceship as you drive down the road? Simply push a button. If you're thinking it's an aftermarket gimmick for boy racers who want their Corsa to growl like a Cambiocorsa, you're wrong. There is a serious point, because in the future - when we're all driving around town in silent-running hybrids and electric vehicles (EVs) - safety legislation will insist that our cars need to generate some sort of sound.

If they don't, the evidence suggests people get hurt. Research from America's National Highway Traffic Safety Administration found that when a hybrid is slowing, stopping, reversing or manoeuvring in a car park, it's twice as likely to be involved in a pedestrian crash than a regular vehicle. Stateside rules are already on the way. The Pedestrian Safety Enhancement Act has the backing of former presidential candidate Senator John Kerry. Earlier this year Japan published guidelines on banning silent motoring and the EU will inevitably follow suit. The most advanced solution to date is provided through a joint venture from high-end car audio specialist Harman Automotive and Lotus Engineering, from whose names HALOsonic derives. Their objective was to blend road and engine noise cancellation with sound synthesis. Lotus has developed it, Harman has bought the rights and is in the process of selling it to major car manufacturers. The first production vehicle to use it will be on sale within 12 months.

Tony Harberman, Harman's sales director, says: "We can generate a sound, tune it to the throttle input and play it back through speakers. They can be inside the car for the driver, or outside for pedestrians. We don't want to create noise pollution. "One of the advantages of hybrids and EVs is the lack of noise, so we need to ensure the sound is projected only towards pedestrians and other road users." The external speaker is built into the nearside front bumper - the point closest to pedestrians on the pavement - and would swap sides for left-hand drive models. At speeds above about 30mph it can be switched off, because tyre noise on the road surface takes over. The key issue is what sound it should emit. "It's strange for us because as an audio company we have always taken the approach that we should reproduce sound the way the creator, the musician, intended," says Harberman. "Now we have to create something ourselves. It can literally be anything. It could have cloppety hooves if you wanted, but [in practice] it's got to be something the recipient is going to understand as a car."

The technology has been demonstrated to the bulk of volume car manufacturers, all of whom appreciate its safety benefits. The most interesting thing, according to Harberman, is the range of different approaches they adopted. "At the conservative end," he says, "you have those who want a hybrid or EV to sound like the rest of their range. "At the other, people want to experiment. They don't want it to be like a petrol or a diesel engine and want to use it as a sensory engagement with the brand." As well as the actual sounds being created, three other factors are key to avoiding accidents. The listener instantly needs to know where the sound is coming from in relation to where they are, a rough estimate of speed and whether it's accelerating or decelerating. Tricks with pitch and volume help solve these problems, and fake gearchanges can be added for extra realism. It's all just a question of programming software algorithms, which have an interesting history. Lotus originally created them during the 1980s, for its active suspension systems in Formula One.
