::: MADE IN Toronto. Again!

There’s one thing that I’ve learned about Canadians.

WE HATE losing.

In hockey… or in AVRO Arrows.

I must again lament the loss of the Arrow… because it is in so DEEPLY INGRAINED in the Canadian psyche. In the psyche of Canadians that matter, that is.

NOW CANADIANS, instead of lamenting (with Kleenex in hand) over picture books of a plane that ONCE WAS… it’s not too late to tell the story of the Arrow to your son, this time with the Arrow right behind you!

Where will you find an ARROW?

Well, at the Toronto Aerospace Museum.

Life-size, and in all its’ regalia (day-glo colour scheme) ~

But we’re Canadians, so the story can’t end there!

We need to come full-circle; we need a flying version.

So a 2/3 scale Arrow is being built, right now, in Alberta.

And so, the Arrow WILL TAKE to the skies yet again.

AND A government that tried to erase the Arrow (OUR SYMBOL of advanced technological achievement, and of a “little” country that could) from our Canadian conscience forever, ultimately, failed, In the end.

Yes, THERE WAS an Arrow, there is an Arrow… in fact, damn it… ARROWS are springing up all over the country.

‘nuff said ~

But jus’ so you don’t think the AVRO Arrow was any ole’ plane… here are:


• First a/c designed with digital computers being used for both aerodynamic analysis and designing the structural matrix (and a whole lot more).
• First a/c design to have major components machined by CNC (computer numeric control); i.e., from electronic data which controlled the machine.
• First a/c to be developed using an early form of "computational fluid dynamics" with an integrated "lifting body" type of theory rather than the typical (and obsolete) "blade element" theory.
• First a/c to have marginal stability designed into the pitch axis for better maneuverability, speed and altitude performance.
• First a/c to have negative stability designed into the yaw axis to save weight and cut drag, also boosting performance.
• First a/c to fly on an electronic signal from the stick and pedals. i.e., first fly-by-wire a/c.
• First a/c to fly with fly by wire AND artificial feedback (feel). Not even the first F-16's had this.
• First a/c designed to be data-link flyable from the ground.
• First a/c designed with integrated navigation, weapons release, automatic search and track radar, datalink inputs, home-on-jamming, infrared detection, electronic countermeasures and counter-countermeasures operating through a DIGITAL brain.
• First high wing jet fighter that made the entire upper surface a lifting body. The F-15, F-22, Su-27 etc., MiG-29, MiG 25 and others certainly used that idea.
• First sophisticated bleed-bypass system for both intake AND engine/exhaust. Everybody uses that now.
• First by-pass engine design. (all current fighters have by-pass engines).
• First combination of the last two points with an "ejector" nozzle that used the bypass air to create thrust at the exhaust nozzle while also improving intake flow. The F-106 didn't even have a nozzle, just a pipe.
• Use of Titanium for significant portions of the aircraft structure and engine.
• Use of composites (not the first, but they made thoughtful use of them and were researching and engineering new ones).
• Use of a drooped leading edge and aerodynamic "twist" on the wing.
• Use of engines at the rear to allow both a lighter structure and significant payload at the centre of gravity. Everybody copied that.
• Use of a LONG internal weapons bay to allow carriage of specialized, long-range standoff and cruise missiles. (not copied yet really)
• Integration of ground-mapping radar and the radar altimeter plus flight control system to allow a seriousstrike/reconnaissance role. The first to propose an aircraft be equally adept at those roles while being THE air-superiority fighter at the same time. (Few have even tried to copy that, although the F-15E is an interesting exception.)
• First missile armed a/c to have a combat weight thrust to weight ratio approaching 1 to 1. Few have been able to copy that.
• First flying 4,000 psi hydraulic system to allow lighter and smaller components.
• First oxygen-injection re-light system.
• First engine to have only two main bearing assemblies on a two-shaft design.
• First to use a variable stator on a two-shaft engine.
• First use of a trans-sonic first compressor stage on a turbojet engine.
• First "hot-streak" type of afterburner ignition.
• First engine to use only 10 compressor sections in a two-shaft design. (The competition was using 17!!)

The Avro Arrow was one of Canada's finest aviation achievements, even though it never entered service.
