Brockholes Village Visitor Centre in Preston, Lancashire, England – August 2011
At Brockholes – a wildlife reserve near Preston – the floating visitor centre offers a reassuring glimpse into a flood-proof future
If you turn off the M6, on the ragged edge of Preston, and follow some brown badger signs through a series of truck-filled roundabouts and ramps, you suddenly see a huddle of roofs above a lake, which look like a bronze-age settlement. The view recalls those meticulous yellow-brown reconstructions you get in old, earnest children’s books, and you half expect to see men carrying spears and dead deer, and the smoke of a campfire.
It is in fact a brand-new visitor centre for the just-opened Brockholes nature reserve, and rather than spear-carriers you see citizens of local cities wearing sensible outdoor clothes. It is a complex of buildings with claims on the future rather than the distant past, in that it aims to be extraordinarily sustainable. And it floats.
Brockholes sits on a concrete raft, made buoyant by hollow chambers, held by four steel posts to stop it drifting across the lake. This is the building’s way of dealing with flooding, to which the site is prone. It can rise up to three metres, which would only be necessary in a catastrophe, but will regularly go up and down by 400mm over a year. Whether we are immersed by the effects of climate change or simply persist in our fondness for building on flood plains, floating buildings might come to seem like a very good idea. "People have been in denial about flood risk," says the building’s architect, Adam Khan.
Brockholes is an overlap of wildness and industry. It has been formed over 10 years out of a former gravel quarry, with a range of habitats added to existing woodlands and water to "create a microcosm of what old Lancashire was like". It has been "carefully crafted" to attract different species and is aimed less at dedicated bird-watchers and nature lovers than the general public of the big cities an hour’s drive or so away – Manchester, Liverpool, Leeds – and at tourists on their way to the nearby Lake District. The idea is to introduce people to nature who don’t see enough of it.
Its buildings serve the usual needs of such places – cafe, shop, information – but also host a large education space and a series of conference rooms that will be rented out to generate income. Naturally, in such a place, they have to be scrupulously environmental, and so they are designed to achieve the "outstanding" category in the official measure of such things. (The British Research Establishment Environmental Assessment Method, if you really want to know, or Breeam.) Until recently, buildings could only be "good" or "excellent"; Brockholes is on course to be the first building in its particular niche to achieve "outstanding", although the final judgment will not be made until it has been in use for a while.
Breeam concerns itself with everything from heating and ventilation to the height of light fixtures off the ground, to the sources of materials, the energy that goes into materials, their durability, their potential for recycling, and the distance they travel to the site.
Often, the pursuit of Breeam’s approval leads buildings to pursue a box-ticking series of technical fixes, and an assembly of products designed to fulfil their requirements without much thought to how they look and feel. At Brockholes, Adam Khan wanted to challenge this "factoid-led" approach, and use the pursuit of sustainability as the means to create more beautiful buildings, not less.
So he designed high, steep-pitched roofs enclosing large volumes (good for air circulation and extraction), clad in oak shakes – rough tiles formed out of tree stumps, which would otherwise be burned as waste. Gutters are in copper (long-life, recyclable), which adds a touch of luxury. Ventilation is entirely natural. The roofs are held up with timber beams made in a precise German process, and arrive on the site "as sharp as pencils". Insulation is a cheap but effective stuff made from recycled newspapers.
Then, charmingly, the building connects with its natural surroundings in a way that cannot be measured by technical indices. Because it floats, it has an intimacy with the water that it would lack if it were ringed with defences against flooding: the water is turned from an enemy into an ally. Reed beds have been planted around the building so that when they are fully grown the roofs will seem to emerge from them. From within, visitors will – in places – be able to look into the reeds, and into spaces carved out of them "like crop circles". In other places they will look onto open water.
The complex’s buildings are arranged around a series of courtyards, which provide both a sense of enclosure and openness to views, and one of which is planted with a little orchard. The oak roofs change
Damaged US Army AH-64 Apache
The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew. The Apache was developed as Model 77 by Hughes Helicopters for the United States Army’s Advanced Attack Helicopter program to replace the AH-1 Cobra. First flown on 30 September 1975, the AH-64 features a nose-mounted sensor suite for target acquisition and night vision systems. The Apache is armed with a 30-millimeter (1.2 in) M230 Chain Gun carried between the main landing gear, under the aircraft’s forward fuselage. It has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire missiles and Hydra 70 rocket pods. The AH-64 features multiple aircraft systems with built-in redundancy to improve survivability in combat; improved crash survivability for the crew has also been prioritized.
The U.S. Army selected the AH-64 over the Bell YAH-63 in 1976, awarding Hughes Helicopters a pre-production contract for two more aircraft. In 1982, the Army approved full production. McDonnell Douglas continued production and development after purchasing Hughes Helicopters from Summa Corporation in 1984. The first production AH-64D Apache Longbow, an upgraded version of the original Apache, was delivered to the Army in March 1997. Production has been continued by Boeing Defense, Space & Security; over one thousand AH-64s have been produced to date.
The U.S. Army is the primary operator of the AH-64; it has also become the primary attack helicopter of multiple nations, including Greece, Japan, Israel, the Netherlands and Singapore; as well as being produced under license in the United Kingdom as the AgustaWestland Apache. U.S. AH-64s have served in conflicts in Panama, the Persian Gulf, Kosovo, Afghanistan, and Iraq. Israel has made active use of the Apache in its military conflicts in Lebanon and the Gaza Strip, while two coalition allies have deployed their AH-64s in Afghanistan and Iraq.
Development[edit] Advanced Attack HelicopterMain article: Advanced Attack Helicopter
Following the cancellation of the AH-56 Cheyenne in 1972, in favor of United States Air Force and Marine Corps projects like the A-10 Thunderbolt II and Harrier, the United States Army sought an aircraft to fill an anti-armor attack role that would still be under Army command; the 1948 Key West Agreement forbade the Army from owning fixed-wing aircraft. The Army wanted an aircraft better than the AH-1 Cobra in firepower, performance and range. It would have the maneuverability for terrain following nap-of-the-earth (NoE) flying. To this end, the US Army issued a Request For Proposals (RFP) for an Advanced Attack Helicopter (AAH) on 15 November 1972. As a sign of the importance of this project, in September 1973 the Army designated their five most important projects, the Big Five with AAH included.
Proposals were submitted by Bell, Boeing Vertol/Grumman team, Hughes, Lockheed, and Sikorsky. In July 1973, the U.S. Department of Defense selected finalists Bell and Hughes Aircraft’s Toolco Aircraft Division (later Hughes Helicopters). This began the phase 1 of the competition. Each company built prototype helicopters and went through a flight test program. Hughes’ Model 77/YAH-64A prototype first flew on 30 September 1975, while Bell’s Model 409/YAH-63A prototype first flew on 1 October. After evaluating test results, the Army selected Hughes’ YAH-64A over Bell’s YAH-63A in 1976. Reasons for selecting the YAH-64A included its more damage tolerant four-blade main rotor and the instability of the YAH-63′s tricycle landing gear arrangement.
A Hughes YAH-64A prototypeThe AH-64A then entered phase 2 of the AAH program. This called for building three pre-production AH-64s, and upgrading the two YAH-64A flight prototypes and the ground test unit up to the same standard.[12] Weapons and sensor systems were integrated and tested during this time, including the laser-guided AGM-114 Hellfire missile. The missile’s development had began in 1974.
Production historyIn 1981, three pre-production AH-64As were handed over to the US Army for Operational Test II. The Army testing was successful, but afterward it was decided to upgrade to the more powerful T700-GE-701 version of engine, rated at 1,690 shp (1,259 kW). The AH-64 was named the Apache in late 1981, keeping with the Army’s traditional use of American Indian tribal names for its helicopters and it was approved for full scale production in 1982. In 1983, the first production helicopter was rolled out at Hughes Helicopter’s facility at Mesa, Arizona. Hughes Helicopters was purchased by McDonnell Douglas for $470 million in 1984. The helicopter unit later became part of The Boeing Company with the merger of Boeing and McDonnell Douglas in August 1997. In 1986, the incremental or flyaway c
