AVRO CF-105 Arrow WHIF

Well, I'd first compare the Mk.I and Mk.II station and datum drawings to make certain the reference planes are the same.  Beyond that, my best guess would be that somewhere, erroneous data crept in and keeps getting repeated.

As to the IR sensor location, the attached art shows it nicely.  Myself, I'd rather see the twin system in the wingroots, as on the F-108, but that's strictly personal opinion.

Hi.
In the book "the arrow scrapbook" by Peter Zuuring there  is a infra red sensor on the vertical surface about 2/3 up.So this is what i am building a arrow MK1 with a astra system as a test bed.I have a question that has been nagging me for years,why is the mk2 longer by 4ft.8in. than the mk1 while if you look a the station and datum line drawing the mk2 should be shorter? Is it me or my knowledge of this type of drawing is outdated?
Thanks a lot

Hi Canuck,
as far as the Mk.1 and Mk.2 lengths are concerned, in engineering terms the two 'airframes' were the same length... 910 inches measured from 0 datum. The radomes on the other hand differed in length, the aft end of both radomes was at the same station, 68.5. On the Mk.1 the radome terminated at -26.5 and the Mk.2 at approximately -12 (measured off of the drawing in the Arrowheads book).
Overall lengths (without probes) are therefore 936.5 for the Mk.1 and approximately 922 for the Mk.2. (If you measure to the end of the probe on both aircraft the difference is approx. 18 inches)

The chart on page 119 that gives the lengths of the various types is in error.

Cheers, Jon

Thank you guys.

Aside "real world" mk2, mk3 and mk4 variant planned by Avro before cancellation , I think Arrow future would have followed two paralel ways

- Interceptor variant (sounds logical) with YF-12 weapon system. Become MiG-25 killer in the late 60's.

- Phantom-like variant, Ie fighter bomber.

When Australia sought a Canberra replacement circa 1963, a commission led by Mjr Hancock left Australia and tested the following aircrafts, F-4C, Mirage IV and Vigilante. They also monitored TSR-2 and F-111 programs.
Considering, on one hand  that the Phantom was on the list, on the other hand that the Arrow was in the same league as the Mirage IV and Vigilante (it was even more powerful!) I'm quite sure Australia would have had interest in a
fighter-bomber variant...  

I've made a mistake three days ago. I've red again Le Fana de l'Aviation monography on the Arrow, and come across this marvellous picture of RL-205.
