Mercedes-Benz.

G-Series Vehicles.

This is perhaps one of, if not the best 4X4 in the world? Developed jointly between Germany and Austria is has taken the military, para-military and police security market. The first generation vehicles were built between 1970 to 1979, with the second generation concept being laid down in 1976.

Austrian Steyr Pusch-G entering the market with the U.S from 1993, while the German 1990-96 model was already well established. There are too many sub models to list, but initially powerful engines were employed, I suppose for military towing capability, and recovery of various loads.

The Austrian version looks like a dedicated military vehicle, but the second generation has joined its German counterpart in style and civil looks.

Today there are various civil takes on the Jeep, but they look more car like or SUV/waggons to appeal to private security and farming vehicles.

Mercedez.

Jeeps and four-wheel drive.

For a long time the British landrover series has been seen as ruling the world market in the four by four. Nearly every country in the world produces their own versions of this type of essential off road vehicle and it is the German Mercedez company that over the last thirty years or so have taken the market of many other well know names.

This week we will just have this introduction to the German manufacturer and its other famous off road type the Unimog truck. Please check previous articles on Unimog and 4X4 for further references.

The four by four is used for all off road traffic from farming, search and rescue, police and fire services to ambulances and military activities. Reliable engines and gradient capability along with hauling heavy loads must be the essential elements over that of immediate comfort. Here we are not really dealing with a civilian vehicle like others. many other 4X4 contain many gimmicks to sell them to the general public.

Blade Runners. Part-Two.

Russia.

The Soviet Union took advantage of this platform and developed several military and civil crafts.
The largest being the Babochka (Butterfly), which became a Naval Fast attack Missile Hydrofoil, capable of speeds in excess of 50 Knots. It was powered by 3x 12-15000 hp Diesel turbine engines.

These type of craft were designed to patrol river estuaries and to intercept intruders. Speed was initially essential but as missile technology and satellite linked systems have improved a hostile could be knocked out at some distance.

Hydrofoils are venerable to loosing their legs, but speed and system technology has improved their chances as a fighting machine, Russian went on to develop slightly smaller FAC and a whole host of civil hydrofoils as ferries in their vast country where in some places this is the only suitable means of travel.

Blade Runners. Part-One.

An Introduction to the Hydrofoil.

This is perhaps the most prolific ship design that has ever been conceived, to lift up a weight on a blade. today we associate blade running with athletics and that is an amazing feat of engineering in its own right.

The era of the Hydrofoils were the 1950's and it seems there was great competition across the globe to build and have one. Italy, Russia and the United State of America, took full opportunity to build them in all sizes and sleekness of design. 

Bolivian Arrow, 14-ton, 40 seater, Russian Burevestnik, 41-67-tom 130-150 seat river ferry, Italian RHS 70, 32-ton, 71 seat passenger ferry and the U.S Flagstaff 1 (PHG-1) US Coastguard 67.5-ton, with a 40knot speed.

Today they are not as popular, as they once were but they remain in operation in several countries as a novelty design concept.

The Airbus Story. Part-One.

From A300 to A350.

The beginning of the Airbus story started in 1965, when British European Airlines proposed a 200 seat aircraft to compensate on the United States Boeing model 747. But it was not until the 28th October 1972 that the A300B2 took to the skies on its first test flight.

In 1970 eight European airlines and their national aviation companies from Germany, United Kingdom, Netherlands, France and Spain met to start the development of a total European joint built commercial airliner. 

The 28th June 1973 saw the A300B2 enter production, with the first delivery to Air France on 30th may 1974. This gamble paid off very quickly with orders from forty airlines in twenty-nine countries.
The A300 was reliable and cheap to operate, it could accommodate three crew and 336 passengers, was powered by two General-Electric CF6-50C1 engines.

Cruising speed 911km/hr at 9450 metres and a range of 5375Km. Other airlines to operate the aircraft were Air India, Saudi and Thai Airways.
