US military is developing SILENT motorcycles


comments

An elite group of special forces silently race across enemy lines on stealth motorcycles that fighters would never suspect were coming.

That's the scenario the US military is hoping for with its development of the 'Silent Hawk' – a hybrid engine dirt bike for use in reconnaissance missions.

The idea is that for normal operations, the bike would use diesel, gasoline or jet fuel. But when it gets closer to the enemy, it would run almost silently on electricity.

According to its makers, Virginia-based Logos Technologies, the bike's louder mode would be slightly louder than the average vacuum cleaner, reaching up to 75 decibels.

The company also says it Silent Hawk could travel over difficult terrain on its hybrid engine over a sustained period at 55 miles per hour (88km/h).

The combustion engine will also be removable, which means Silent Hawk can become all-electric, and also shed weight or take out problem parts.

On its own, the bike's battery can power it for up to 50 miles (80km). However, the concept is still under development and further specifications have yet to be announced.

SILENT ELECTRIC AIRCRAFT COULD BE ROLLED OUT IN 20 YEARS

Spectators at air shows are usually impressed by the boom of fighter jets flying overhead.

But aeroplane fans at the Berlin Air Show were also wowed by the eerily quiet flight of Airbus Group's fully-electric aircraft last year.

The prototype two-seater made its maiden flight in March but only took to the skies in front of the public in May. It was designed from scratch, from its electrical propulsion and energy management system to its safety features.

Airbus hopes that the prototype is one step towards the aerospace industry using regional jets powered by hybrid electric engines, which would slash its carbon dioxide emissions.

The development of a regional plane, seating between 70 and 90 people that can take off and land using electric power, could take between 15 and 20 years, Airbus Group Chief Technology Officer Jean Botti told reporters in Munich.

The Defense Advanced Research Projects Agency (Darpa) began the motorcycle project last year, and has now granted its makers an award to develop it further.

Logos says it now plan 'to proceed with an aggressive Phase II program plan, with the goal of developing and testing the first operational prototype in only 18 months.'

The U.S. Special Operations Command previously tried to use an all-electric Zero MMX bike for the same purpose, but the battery only lasted two hours.

It's not just commandos will soon be receiving steal motorbikes. In August, it was announced that police forces could use the bikes to approach criminals undetected.

The bike, designed by Zero Motorcycles in northern California, has a top speed of up to 98 mph (158 km/h), allowing police to chase criminals down if the stealth approach fails.
