The return of the airship: under the bonnet of the world’s longest aircraft

Published

on

The world’s longest aircraft has been unveiled – a unique, helium-filled hybrid airship that, it’s designers say, can offer environmentally friendly and sustainable flight. Its development signals a return to vogue for an often forgotten mode of travel, completing a story almost 100 years in the making.

The first of the two 700-foot-long (210m) hangars of RAF Cardington, in Bedfordshire, was constructed in 1915 to enable the development of airships for the war effort.

Two aircraft were built, the R31 and the R32, designed to protect British fleets from marauding German U-boats. The first, R31, was finally declared ready on November 6 1918, five days before the end of the war.    

In 1925, when the British government decided to resurrect the airship programme, it ordered Cardington to be revived for the development of a new airship, the R101.

The hangar was extended to 812 feet (248m) and a second was erected beside it, reassembled from a dismantled hangar taken from Norfolk.

When built, the R101 was the largest flying aircraft in the world, not surpassed until the Hindenburg took to the skies seven years later. Tragically, the R101 shared the same fate as its more infamous successor.

On October 5 1930, the R101 crashed in France, killing 48 people. It was the end of Britain’s airship programme.

Just shy of one century after Cardington’s construction, the now privately owned site is home to the Airlander, a project of the designer and manufacturer Hybrid Air Vehicles (HAV).

Once again, Cardington is playing a crucial part in efforts to revolutionise the future of transport. Unveiled on Thursday in the only hangar big enough to accommodate it, the £60m Airlander, a 302ft (92m) long behemoth, is about 60ft (18m) longer than the world’s biggest airliners, the Airbus A380 and Boeing 747-8.

What makes the craft so special is that it not only generates lift from the gas it stores, but also from its unique design. An aerodynamic shape means that the craft gains lift from forward motion, in the same way as an aeroplane wing.

It is also worth pointing out at this stage that the helium-filled balloon is far safer than its volatile hydrogen-filled predecessors. Originally designed for the US military, the Airliner is almost impervious even to small arms fire.

Aviation enthusiast and shareholder of HAV, Bruce Dickinson, perhaps better known as the lead singer of Iron Maiden, may not be far off the mark when he describes the Airlander as “a game changer”.

Speaking to the BBC, Dickinson said how the Airlander is 70% greener than a cargo plane. It requires only two crewmembers, can be landed by remote control, and doesn’t need a runway (or even solid ground; it can land on water). It can carry 50 tonnes of cargo, and deposit it anywhere in the world, in places with no road, rail or sea infrastructure.

While it is easy to see what the US military saw in such capabilities, the humanitarian applications of such technology are also obvious.

Among those seeing the potential is the British government, which has provided a £2.5m grant to HAV. “Here is a British SME that has the potential to lead the world in its field”, commented business secretary Vince Cable.

HAV is of course not the only firm in this field. The US manufacturer Worldwide Aeros Corp is also working on a hybrid, dubbed the Aeroscraft, that it hopes could represent the future of freight transportation.

Other projects, such as Seymourpowell’s conceptual Aircruise, reimagine the airship in slightly different ways. Essentially a flying hotel, the Aircruise is a giant, vertical airship lifted by hydrogen and powered by solar energy.

While these projects are still some way from completion – the Airlander’s inaugural passenger flight is penned in for 2016 – it seems certain that the dawn of a new generation of airships isn’t far off. With the safety issues that come with being suspended in the sky by a ball of flammable gas taken out of the equation, there seems to be little stopping it.

There is an urgent need for sustainable air transport. To fly by commercial jet is currently to inflict the gravest damage upon the climate that an average human being can do. There is no sign that the aviation industry is set to dramatically and urgently clean up its act, and the Intergovernmental Panel on Climate Change predicts that by 2050, aviation could generate anywhere between 5% and 15% of all manmade emissions.

Though the technology cannot hope to replace the convenience and immediacy of commercial passenger aviation any time soon, be it as a bit-part player or an inspiration, the return of the airship may prove timely.

“The airship has always been with us”, Bruce Dickinson added. “It’s just been waiting for the technology to catch up.”

What is going green?

Going green means to live life in a way that is environmentally friendly for an entire population. It is the conservation of energy, water, and air. Going green means using products and resources that will not contaminate or pollute the air. It means being educated and well informed about the surroundings, and how to best protect them. It means recycling products that may not be biodegradable. Companies, as well as people, that adhere to going green can help to ensure a safer life for humanity.

The first step in going green

There are actually no step by step instructions for going green. The only requirement needed is making the decision to become environmentally conscious. It takes a caring attitude, and a willingness to make the change. It has been found that companies have improved their profit margins by going green. They have saved money on many of the frivolous things they they thought were a necessity. Besides saving money, companies are operating more efficiently than before going green. Companies have become aware of their ecological responsibility by pursuing the knowledge needed to make decisions that would change lifestyles and help sustain the earth’s natural resources for present and future generations.

Making needed changes within the company

After making the decision to go green, there are several things that can be changed in the workplace. A good place to start would be conserving energy used by electrical appliances. First, turning off the computer will save over the long run. Just letting it sleep still uses energy overnight. Turn off all other appliances like coffee maker, or anything that plugs in. Pull the socket from the outlet to stop unnecessary energy loss. Appliances continue to use electricity although they are switched off, and not unplugged. Get in the habit of turning off the lights whenever you leave a room. Change to fluorescent light bulbs, and lighting throughout the building. Have any leaks sealed on the premises to avoid the escape of heat or air.

Reducing the common paper waste

Modern technologies and state of the art equipment, and tools have almost eliminated the use of paper in the office. Instead of sending out newsletters, brochures, written memos and reminders, you can now do all of these and more by technology while saving on the use of paper. Send out digital documents and emails to communicate with staff and other employees. By using this virtual bookkeeping technique, you will save a bundle on paper. When it is necessary to use paper for printing purposes or other services, choose the already recycled paper. It is smartly labeled and easy to find in any office supply store. It is called the Post Consumer Waste paper, or PCW paper. This will show that your company is dedicated to the preservation of natural resources. By using PCW paper, everyone helps to save the trees which provides and emits many important nutrients into the atmosphere.

Make money by spreading the word

Companies realize that consumers like to buy, or invest in whatever the latest trend may be. They also cater to companies that are doing great things for the quality of life of all people. People want to know that the companies that they cater to are doing their part for the environment and ecology. By going green, you can tell consumers of your experiences with helping them and communities be eco-friendly. This is a sound public relations technique to bring revenue to your brand. Boost the impact that your company makes on the environment. Go green, save and make money while essentially preserving what is normally taken for granted. The benefits of having a green company are enormous for consumers as well as the companies that engage in the process.

Increasing your home’s energy efficiency is one of the smartest moves you can make as a homeowner. It will lower your bills, increase the resale value of your property, and help minimize our planet’s fast-approaching climate crisis. While major home retrofits can seem daunting, there are plenty of quick and cost-effective ways to start reducing your carbon footprint today. Here are five easy projects to make your home more sustainable.

1. Weather stripping

If you’re looking to make your home more energy efficient, an energy audit is a highly recommended first step. This will reveal where your home is lacking in regards to sustainability suggests the best plan of attack.

Some form of weather stripping is nearly always advised because it is so easy and inexpensive yet can yield such transformative results. The audit will provide information about air leaks which you can couple with your own knowledge of your home’s ventilation needs to develop a strategic plan.

Make sure you choose the appropriate type of weather stripping for each location in your home. Areas that receive a lot of wear and tear, like popular doorways, are best served by slightly more expensive vinyl or metal options. Immobile cracks or infrequently opened windows can be treated with inexpensive foams or caulking. Depending on the age and quality of your home, the resulting energy savings can be as much as 20 percent.

2. Programmable thermostats

Programmable thermostats have tremendous potential to save money and minimize unnecessary energy usage. About 45 percent of a home’s energy is earmarked for heating and cooling needs with a large fraction of that wasted on unoccupied spaces. Programmable thermostats can automatically lower the heat overnight or shut off the air conditioning when you go to work.

Every degree Fahrenheit you lower the thermostat equates to 1 percent less energy use, which amounts to considerable savings over the course of a year. When used correctly, programmable thermostats reduce heating and cooling bills by 10 to 30 percent. Of course, the same result can be achieved by manually adjusting your thermostats to coincide with your activities, just make sure you remember to do it!

3. Low-flow water hardware

With the current focus on carbon emissions and climate change, we typically equate environmental stability to lower energy use, but fresh water shortage is an equal threat. Installing low-flow hardware for toilets and showers, particularly in drought prone areas, is an inexpensive and easy way to cut water consumption by 50 percent and save as much as $145 per year.

Older toilets use up to 6 gallons of water per flush, the equivalent of an astounding 20.1 gallons per person each day. This makes them the biggest consumer of indoor water. New low-flow toilets are standardized at 1.6 gallons per flush and can save more than 20,000 gallons a year in a 4-member household.

Similarly, low-flow shower heads can decrease water consumption by 40 percent or more while also lowering water heating bills and reducing CO2 emissions. Unlike early versions, new low-flow models are equipped with excellent pressure technology so your shower will be no less satisfying.

4. Energy efficient light bulbs

An average household dedicates about 5 percent of its energy use to lighting, but this value is dropping thanks to new lighting technology. Incandescent bulbs are quickly becoming a thing of the past. These inefficient light sources give off 90 percent of their energy as heat which is not only impractical from a lighting standpoint, but also raises energy bills even further during hot weather.

New LED and compact fluorescent options are far more efficient and longer lasting. Though the upfront costs are higher, the long term environmental and financial benefits are well worth it. Energy efficient light bulbs use as much as 80 percent less energy than traditional incandescent and last 3 to 25 times longer producing savings of about $6 per year per bulb.

5. Installing solar panels

Adding solar panels may not be the easiest, or least expensive, sustainability upgrade for your home, but it will certainly have the greatest impact on both your energy bills and your environmental footprint. Installing solar panels can run about $15,000 – $20,000 upfront, though a number of government incentives are bringing these numbers down. Alternatively, panels can also be leased for a much lower initial investment.

Once operational, a solar system saves about $600 per year over the course of its 25 to 30-year lifespan, and this figure will grow as energy prices rise. Solar installations require little to no maintenance and increase the value of your home.

From an environmental standpoint, the average five-kilowatt residential system can reduce household CO2 emissions by 15,000 pounds every year. Using your solar system to power an electric vehicle is the ultimate sustainable solution serving to reduce total CO2 emissions by as much as 70%!

These days, being environmentally responsible is the hallmark of a good global citizen and it need not require major sacrifices in regards to your lifestyle or your wallet. In fact, increasing your home’s sustainability is apt to make your residence more livable and save you money in the long run. The five projects listed here are just a few of the easy ways to reduce both your environmental footprint and your energy bills. So, give one or more of them a try; with a small budget and a little know-how, there is no reason you can’t start today.
