History

The new Bombardier Learjet 45 is Learjet's latest entry into the medium size corporate jet market.
Bombardier owned Learjet announced it was developing the Model 45 at the US National Business Aircraft Association's annual convention in Dallas in September 1992. First flight was on October 7 1995 (the 32nd anniversary of the original Lear 23), and, after some delays, US FAA certification was granted on September 22 1997. The first customer aircraft was delivered in January 1998
The 45 is of classic Learjet design and layout. However a number of key design changes were made early into the 45's design life including a larger fin and rudder, extended engine pylons, smaller delta fins, full span elevators, and single piece flaps.
Larger than the Learjet 31 and smaller than the 60, Learjet states that the 45's 1.50m (4.9ft) high and 1.55m (5.1ft) wide cabin will provide more head and shoulder room than any other aircraft in its class. The cabin is designed to accommodate double club seating, a galley and a full width aft rest room, while eight windows line each side of the cabin.
The flightdeck features a four screen (two primary flight displays and two multifunction displays) Honeywell Primus 1000 integrated avionics suite, while an APU is standard.
The 20 FADEC equipped version of the proven AlliedSignal TFE731 engine was developed in cooperation with Learjet for the 45 and incorporates 60 design changes to increase fuel economy and reduce operating and maintenance costs.
While Learjet retains overall 45 program leadership, and is responsible for the aircraft's design, other Bombardier Group companies participate in Learjet 45 production. De Havilland Inc in Canada is responsible for wing construction, while Shorts of Northern Ireland in the UK builds the fuselage and empennage.

Super mid size corporate jet

History

Bombardier's all new Challenger 300 is a transcontinental range eight-seat corporate jet which will sit in the company's model line-up between the Learjet 60 and Challenger 604. It is developed for a non-stop 5471km (3100nm) mission with a load of eight passengers and NBAA IFR reserves.

Bombardier revealed it was developing the Continental (as it was known then) at the 1998 National Business Aircraft Association's annual convention in Las Vegas in October 1998. The program was officially launched at the Paris Air Show on June 13, 1999. It would compete for what Bombardier sees as a market for 1230 super mid size corporate jets by 2012. The Continental was renamed Challenger 300 on September 9, 2002.

The new jet will compete with the Hawker Horizon and Galaxy, among others. Bombardier claims the Continental will offer 39% more cabin space and 20% more range "than the leading mid size business jet". It is also claimed to have a larger cabin than the intercontinental range Falcon 50 and high speed Citation X.

Features of the Challenger 300 are a cockpit equipped with Collins Pro Line 21 four-tube EFIS, EICAS, TCASII, and EGPWS avionics, a standard eight place double club interior with galley and toilet, stand-up headroom, a flat floor, an auxiliary power unit and thrust reversers, all metal construction and a large area wing for good field performance.

The Challenger 300 has a primarily light-alloy structure, with composites used for some non-structural items. The fuselage is of a semi-monocoque construction with frames and stringers. The wing has two spars.

The first Continental risk sharing partner is AlliedSignal, which will supply its new FADEC equipped AS-907 turbofan to power the new jet, as well as the engine nacelles and thrust reversers. The AS-907 itself is developed with a number of partner companies, with AIDC of Taiwan selected to provide the fan.

Wing/fuselage mating of the first aircraft was achieved on November 19, 2000. The first flight was made on August 14, 2001, and certification is due in the third quarter of 2002. The aircraft will start corporate service in 2003.

The Challenger 300 made its official debut at Orlando Executive Airport on September 8, 2002 at the NBAA Convention. At that time, four aircraft were flying in the test program.

Type

Twin engine light utility helicopters

History

Bell's 206LT TwinRanger, is, as its name suggests, a new build twin engined development of the 206L LongRanger, while Tridair helicopters in the USA offers its twin engine Gemini ST conversion for existing LongRangers.

The name TwinRanger predates the current 206LT to the mid 1980s when Bell first looked at developing twin engine version of the LongRanger. The Model 400 TwinRanger did fly (maiden flight was on April 4 1984) and it featured two Allison 250 turboshafts, the four blade main rotor developed for the military Bell 406/OH58 Kiowa and a reprofiled fuselage, but development was later suspended.

The current 206LT TwinRanger is based on Tridair Helicopters' Gemini ST conversion program. Tridair announced it was working on a twin engine conversion of the LongRanger in 1989, and the prototype flew for the first time on January 16 1991. Full FAA certification was awarded in November and covers the conversion of LongRanger 206L1s, L3s and L4s to Gemini ST configuration.

In mid 1994 the Gemini ST made history when it was certificated as the first Single/Twin aircraft, allowing it to operate either as a single or twin engine aircraft throughout all phases of flight. This unique certification allows it to operate with a single engine for maximum economy (for ferrying etc), with the extra redundancy and performance of a twin available when required.

Bell's 206LT TwinRanger is a new build production model equivalent to Tridair's Gemini ST and based on the LongRanger IV. The first example was delivered in January 1994. The TwinRanger will be replaced by the 427 which is currently under development.

N-219 Generasi terbaru pesawat produksi PT Dirgantara Indonesia

BeritaUnik.net – Saat ini, penerbangan perintis di beberapa wilayah Nusantara seperti Papua masih menggunakan pesawat-pesawat produksi lama, seperti Twin Otter. Beberapa unit yang ada telah tidak layak pakai sehingga diperlukan pesawat yang lebih modern.
Karenanya, sejak tahun 2006, PT Dirgantara Indonesia mengembangkan pesawat N219 berkapasitas 19 orang untuk menggantikan peran pesawat perintis yang ada sekarang. Saat ini, uji aerodinamika pesawat tersebut telah dituntaskan.
N-219 Generasi terbaru pesawat produksi PT Dirgantara Indonesia
“Pengembangan pesawat jenis ini biasanya memakan waktu 3 tahun. Namun, kita mungkin akan selesaikan 2-2,5 tahun,” kata Andi Alisjahbana, Direktur Aerostruktur PT Dirgantara Indonesia, Selasa (28/12/2010) di Jakarta. Jadi, tahun 2013, pesawat mungkin sudah bisa diluncurkan.
Agar tidak mengalami kegagalan seperti pesawat CN 250, pihak PTDI akan memproduksi pesawat berdasarkan order. “Kami akan buat 25 unit dulu nantinya. Kami akan mengupayakan seluruhnya terjual dahulu,” kata Andi. Pembuatan sejumlah unit memerlukan dana sekitar Rp 1 triliun. Jumlah ini menurut Andi cukup minim untuk membuat pesawat. Ia menargetkan, sejumlah pesawat akan dibeli oleh pemerintah daerah.
Andi juga mengatakan, spesifikasi pesawat N219 dirancang sesuai dengan kondisi geografis Indonesia. Pesawat ini mampu mendarat di landasan yang pendek sehingga bisa diaplikasikan di wilayah terpencil dengan lahan terbatas. “Pesawat ini juga dirancang bisa membawa bahan bakar tambahan. Kita menyadari bahwa tidak setiap daerah memiliki tempat pengisian bahan bakar,” demikian Andi mengungkapkan kelebihan pesawat N219.
Sementara itu, Budi Santoso selaku Direktur Utama PT Dirgantara Indonesia mengatakan bahwa pengembangan pesawat ini didasarkan pada karakteristik geografis Indonesia. “Kondisi geografis kita berbeda dengan negara lain. Kita harus punya solusi sendiri,” katanya. Bagi Budi, pengembangan pesawat kecil yang mampu menjangkau wilayah terpencil sangat pas. “Banyak wilayah Indonesia yang tak mudah dijangkau dengan transportasi darat. Pesawat perintis bisa menjadi solusi,” paparnya.
Pesawat N219 memiliki potensi besar untuk dipasarkan ke daerah-daerah seperti Sumatera dan Papua. Pesawat ini juga ditargetkan bisa dipasarkan ke negara lain yang masih membutuhkan, misalnya negara-negara di Afrika.

Indonesia 'berminat membeli pesawat tempur Inggris'

Surat kabar Inggris The Times melaporkan Indonesia secara informal melobi Inggris mengenai kemungkinan membeli sampai 24 unit pesawat jet multi-tempur Eurofighter Typhoon.

Penjualan itu, bila terlaksana, akan bernilai sekitar £5 miliar atau hampir Rp71 triliun.

Secara terpisah, perusahaan peralatan militer Inggris BAE Systems menawarkan untuk meremajakan pesawat-pesawat jet Hawk yang sudah dimiliki Indonesia.
Kepala Biro Humas Kementerian Pertahanan Brigjen I Wayan Midhio, membenarkan bahwa memang ada pembicaraan mengenai peremajaan pesawat Hawk, namun membantah ada rencana pembelian pesawat multi-tempur Eurofighter Typhoon.
"TNI AU sedang membahas mengenai Eurocopter, helikopter Eropa. Tetapi masih dievaluasi untuk dibahas di tingkat TNI AU, belum dibahas di kementrian (pertahanan)," kata Wayan Midhio.

Indonesia berminat membeli pesawat tempur Inggris

Indonesia dilaporkan berminat membeli 24 pesawat jet multi-tempur Eurofighter Typhoon dari Inggris. Peneliti CSIS Evan Laksamana berbicara kepada Emilda Rosen.

Saat ini Indonesia memiliki beragam jenis pesawat tempur, diantaranya pesawat Hawk buatan Inggris, F-16 buatan Amerika dan pesawat Sukhoi buatan Rusia.
Peneliti CSIS urusan pertahanan Evan Laksamana mengatakan, keragaman ini merupakan upaya diversifikasi pemerintah terhadap peralatan pertahanan, karena Indonesia beberapa kali dikenakan embargo pembelian peralatan dari negara-negara Barat seperti Amerika dan Inggris.
Pemerintah Inggris di bawah Partai Buruh pada tahun 1999 melarang penjualan peralatan pertahanan atas dugaan pesawat-pesawat pengebom buatan Inggris digunakan untuk mengebom warga sipil di Timor Timur, Papua dan Aceh.
Pada tahun yang sama Kongres Amerika menerapkan pelarangan penjualan senjata kepada Indonesia atas alasan serupa, yang baru dicabut pada tahun 2005.
Namun Evan Laksamana melihat, upaya diversifikasi pembelian senjata yang tidak dibarengi rencana jangka panjang akan menjadi masalah di kemudian hari.
"Dari segi sistemnya, dari segi maintenance, dari segi biaya yang harus dikeluarkan untuk melatih orang-orang yang sama. Dalam situasi darurat misalnya, belum tentu orang yang sudah dilatih untuk menerbangkan Sukhoi bisa menerbangkan Typhoon. Jadi biaya yang dikeluarkan akan lebih banyak,"

Boeing Rilis Pesawat Jumbo Terbaru Boeing 747-8

Washington - Raksasa pesawat terbang Boeing merilis pesawat jumbo terbaru Boeing 747-8 Intercontinental yang menjanjikan pengalaman kemewahan bagi para penumpang. Pesawat dengan 467 kursi penumpang tersebut diluncurkan dengan harapan untuk menghidupkan kembali daya tarik saat kelahiran pertama pesawat Boeing 747 pada 42 tahun silam.

Menurut pihak Boeing, seperti diberitakan kantor berita AFP, Senin (14/2/2011), pesawat ini akan menggunakan lebih sedikit bahan bakar dan memberikan kenyamanan lebih bagi para penumpang dibandingkan versi Boeing sebelumnya. Pesawat dengan panjang lebih dari 76 meter ini akan menjadi pesawat penumpang terpanjang di dunia. Pesawat yang menampilkan teknologi-teknologi terbaru ini diharapkan untuk menyaingi pesawat rival, Airbus A380.

Peluncuran model Boeing terbaru ini dilakukan di depan sekitar 10 ribu orang yang menghadiri acara tersebut yang digelar di fasilitas produksi Boeing di Everett, Washington, AS.

Acara yang digelar pada Minggu, 13 Februari pagi waktu setempat tersebut, dihadiri para pegawai Boeing beserta keluarga mereka serta para tamu undangan yang merupakan orang-orang penting dari sejumlah industri.

Pesawat ini panjangnya 5,8 meter lebih panjang dari seri terdahulu 747-400, sehingga menjadikan Boeing 747-8 ini sebagai pesawat penumpang terpanjang di dunia saat ini. Pesawat jumbo dengan kabin dua lantai ini tercatat pada harga US$ 317,5 juta.

Pihak Boeing menyatakan, pesawat 747-8 baru akan pertama kali digunakan oleh publik setelah dikirimkan pada maskapai penerbangan Jerman, Lufthansa pada tahun 2012 mendatang.
