Ball-Bartoe Jetwing

The Ball-Bartoe JW-1 Jetwing was a US research aircraft flown in the 1970s to investigate blown wing technology.

Design and development

The Jetwing was a small, mid-wing design powered by a turbofan and fitted with tail-wheel undercarriage. The upper surface of the swept wings incorporated a slot along 70% span, through which air from the engine's fan stage could be discharged. Mounted above this slot was a small secondary airfoil called an "augmentor", intended to direct the discharged airflow over the wing. With this arrangement, it was found that the aircraft remained controllable at airspeeds as low as 34.76 kn (64.38 km/h; 40.00 mph).

Following the test program, the aircraft was donated to the University of Tennessee Space Institute in Tullahoma, which donated the Jetwing to the Wings Over the Rockies Air and Space Museum in Denver, Colorado in 2007.

General characteristics

Yves Rossy

Yves Rossy (born 27 August 1959) is a Swiss military-trained pilot and an aviation enthusiast. He is known as the inventor of a series of experimental individual jet packs, the latest using carbon-fiber wings for flight. Often referred to as "Jetman", Rossy has sometimes tested and presented new versions of his jet packs in high profile events staged around the world.

Early life and career

Rossy was born in the Swiss canton of Neuchâtel in 1959. He served as a fighter pilot in the Swiss Air Force, where he flew Dassault Mirage IIIs, Northrop F-5 Tiger IIs, and Hawker Hunters. He piloted Boeing 747s for Swissair, and later for Swiss International Air Lines.

Jet wingpack

Rossy developed and built a wing-suit system comprising a backpack equipped with semi-rigid aeroplane-type carbon-fiber wings—with a span of about 2.4 metres (7.9 ft)—powered by four Jet-Cat P200 jet engines, modified from large kerosene-fueled model aircraft engines. This has led to him being referred to in the press by various monikers, such as The Airman, Rocketman, Fusionman, and—most commonly—Jetman.

Sri Lanka

Sri Lanka (/sriːˈlɑːŋkə, -ˈlæŋkə/ or ⁱ/ʃriː-/;Sinhalese - ශ්‍රී ලංකාව, Tamil Ilaṅkai), officially the Democratic Socialist Republic of Sri Lanka and known from the beginning of British colonial rule until 1972 as Ceylon (/sᵻˈlɒnˌ seɪ-ˌ siː-/), is an island country in South Asia near south-east India.

Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest. Its documented history spans 3,000 years, with evidence of pre-historic human settlements dating back to at least 125,000 years. Its geographic location and deep harbours made it of great strategic importance from the time of the ancient Silk Road through to World War II.

A diverse and multicultural country, Sri Lanka is home to many religions, ethnic groups, and languages. In addition to the majority Sinhalese, it is home to large groups of Sri Lankan and Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Vedda. Sri Lanka has a rich Buddhist heritage, and the first known Buddhist writings of Sri Lanka, the Pāli Canon, dates back to the Fourth Buddhist council in 29 BC. The country's recent history has been marred by a thirty-year civil war which decisively ended when Sri Lankan military defeated Liberation Tigers of Tamil Eelam in 2009.

Mount Fuji

Mount Fuji (富士山, Fujisan, IPA: [ɸɯᵝꜜdʑisaɴ]), located on Honshu Island, is the highest mountain in Japan at 3,776.24 m (12,389 ft). An active stratovolcano that last erupted in 1707–08, Mount Fuji lies about 100 kilometres (60 mi) south-west of Tokyo, and can be seen from there on a clear day. Mount Fuji's exceptionally symmetrical cone, which is snow-capped several months a year, is a well-known symbol of Japan and it is frequently depicted in art and photographs, as well as visited by sightseers and climbers.

Mount Fuji is one of Japan's "Three Holy Mountains" (三霊山, Sanreizan) along with Mount Tate and Mount Haku. It is also a Special Place of Scenic Beauty and one of Japan's Historic Sites. It was added to the World Heritage List as a Cultural Site on June 22, 2013. As per UNESCO, Mount Fuji has “inspired artists and poets and been the object of pilgrimage for centuries”. UNESCO recognizes 25 sites of cultural interest within the Mt. Fuji locality. These 25 locations include the mountain itself, Fujisan Hongū Sengen Shrine and six other Sengen shrines, two lodging houses, Lake Yamanaka, Lake Kawaguchi, the eight Oshino Hakkai hot springs, two lava tree molds, the remains of the Fuji-kō cult in the Hitoana cave, Shiraito Falls, and Miho no Matsubara pine tree grove.
