For RobertDyck re Canadian History (focus on Cold War)
https://www.msn.com/en-us/news/technolo … e66a&ei=38
In an era shadowed by the Cold War, the pursuit of technological marvels in the sky was not just a matter of innovation but a strategic imperative. Among the many ambitious projects of the time, one aircraft seemed to leap from the pages of pulp science fiction into the realm of aerial reality. The Avrocar, a Canadian-developed VTOL (Vertical Takeoff and Landing) aircraft, promised a vision of the future that ultimately fell short of its lofty aspirations.
The Avrocar’s journey began in the early 1950s with A.V. Roe (Avro) Aircraft Limited, later known as Avro Canada, embarking on a quest to develop a supersonic fighter-bomber that could vertically lift off the ground. Its circular and flat shape, deviating from conventional aircraft design, caused it to resemble the era’s popular depiction of a “flying saucer.” This resemblance was not mere coincidence, as the period brimmed with public fascination over UFOs, fueled by numerous sightings and a proliferation of extraterrestrial themes in Hollywood films.
The Avrocar aimed to utilize the exhaust from turbojet engines to drive a circular “turborotor,” creating a cushion of air known as “ground effect” for low-altitude floating. On paper, directing the thrust rearwards would propel the vehicle forward, allowing it to accelerate and climb like a traditional jet.
Initial Canadian government funding in 1952 could not sustain the project’s financial demands, leading Avro to pass the torch to the U.S. military in 1958. The U.S. Army envisioned the Avrocar as a subsonic all-terrain transport and reconnaissance craft, while the U.S. Air Force coveted a stealthy VTOL aircraft capable of evading radar and breaking the sound barrier. These divergent requirements signaled the beginning of Avrocar’s troubled development.
Despite early optimism, the Avrocar, designated the VZ-9AV (“VZ” for experimental vertical flight, “9” for the ninth concept, “AV” for Avro), faced severe stability challenges. Wind tunnel tests at NASA’s Ames Research Center and scale model evaluations at Wright-Patterson AFB in Ohio unveiled a grim reality—the Avrocar suffered from aerodynamic instability and insufficient control for high-speed flight, manifesting as “hubcapping,” an uncontrollable pitch and roll motion, when more than three feet off the ground.
The dual prototypes of the Avrocar numbered 58-7055 for the first and a second unnamed, strove to demonstrate the aircraft’s viability. However, the vehicle’s performance fell drastically short of expectations, achieving a maximum speed of only 35 mph—far from the supersonic dream. These shortcomings led to the project’s cancellation in December 1961.

For RobertDyck re recent post about politics...
Please consider revising your post about populations so the last line does not leave the reader with an image of human excrement.
It is not necessary for you to use gutter language, to express yourself. You have many other words available. Please try to use them.
I am trying to attract young people (and their parents) to this forum, to take advantage of Dr. Johnson's course materials.

For RobertDyck re new phpBB3 test account ....
I understand that members of the forum do not have time to read every post, so you may not be aware of the test account that the Admins have set up for evaluation of newer forum software.
Please connect to the Azure test account using the information in the Azure topic.
If you encounter an SQL timeout message please just refresh the page. Azure is a Virtual Machine that goes to sleep and has to be re-awakened.
I'd appreciate your feedback on the site.

For RobertDyck re new phpBB3 test account...
In response to discussions underway between Terraformer and Calliban, I have created a "Projects" category in the new phpBB3 NewMars test forum.
The first project I've created is Large Ship ... please register at the test account and begin filling out the topics.
Don't replicate posts that exist in NewMars... those will be preserved as we go forward.
What I'd like to see is evidence that the new structure will be persuasive to SpaceNut, who has the power to create the same thing in the existing forum.

This deep space vessel is defined by a set of specifications laid down by RobertDyck, Moderator of NewMars.com/forums.
Posts in this topic will be about those specifications.

This post is not about a specific post by RobertDyck, but instead, it is about the key influence he had on the design of the Business Calendar for Mars, which has quietly been gaining momentum in the NewMars.com/forums over recent Mars years.
A topic was created in the new phpBB3 forum site, and it opens with this post:
Martian Calendar Based on Formula by RobertDyck
Post by tahanson43206 » Mon Apr 22, 2024 1:09 pmThis calendar features 28 day months, with four Friday's skipped at the end of the four quarters, and an extended New Year's Eve to align the business calendar with the astronomical calendar.
The weeks are seven days, except for the four weeks at the end of the four quarters.
There is never a need to adjust the length of the calendar, or to add or subtract days, because the Business Calendar and the Astronomical Calendar are aligned to the nanosecond at midnight of New Year's Eve.
Credit goes to RobertDick, Moderator of NewMars.com/forums, for the innovations that yield this reliable calendar for the Planet Mars.

This post is for RobertDyck about the phpBB3 test site ...
SpaceNut has begun learning how to apply advanced Admin tools in the phpBB3 forum, which is safe for experiments.
Please add new forums to the Large Ship Category, to show SpaceNut what you would like to see available here in the NewMars forum.
We have all been living with the structure created 20+ years ago, and it is past time to introduce some modest but meaningful changes.
A Large Ship category would be one you could populate with topics that are suitable for Division of Labor and Specialization, so that you can enlist and direct the efforts of those who might be willing to help you, once you get past the idea of doing everything yourself.
