Canadian Arrow


The Canadian Arrow was a privately funded, early-2000s rocket and space tourism project concept founded by London, Ontario, Canada entrepreneurs Geoff Sheerin, Dan McKibbon and Chris Corke. The project's objective was to take the first civilians into space, on a vertical sub-orbital spaceflight reaching an altitude of 112 km.
Canadian Arrow was considered one of the top three candidates for the X-Prize competition, along with Scaled Composites, and Armadillo Aerospace. Scaled Composites won the competition on October 4, 2004.
The Canadian Arrow team's motto was "making SPACE for you". They have completed the first series of tests on their 57,000 lbf thrust engine and have built a space training centre and a full-scale mock-up of their rocket. After an open nomination process, they also recruited a team of six astronauts from around the world, including several seasoned military pilots and a NASA trained astronaut from Ukraine. Astronaut candidates – the group "Arrow Six" includes David Ballinger, Ted Gow, Terry Wong, Jason Dyer, Larry Clark and Yaroslav "Yarko" Pustovyi, the only member of the team with actual space training.
In November 2010 Geoff Sheerin, the president of Canadian Arrow stated the company is unlikely to fly a Canadian Arrow rocket as a space tourism vehicle.

Design

The Canadian Arrow is a 16.5 m tall two-stage rocket, where the second stage is a three-person space capsule. The Canadian Arrow team's somewhat conservative approach has been to base the design of their rocket engine and aerodynamics on the well proven V-2 design from WWII.

First stage

The rocket's first stage is 10.2 m long and 1.7 m in diameter. It is propelled by a single liquid fuel rocket engine. It produces a thrust of 254 kN. Graphite jet vanes are used for stabilisation before the rocket has reached a velocity high enough for the four fins to be effective. About one minute after ignition, the fuel is depleted and the engine shuts off.

Second stage

The rocket's second stage is 6 m long and 1.7 m in diameter at the base. It carries three astronauts and is propelled by four JATO-type solid rocket engines. These are ignited immediately after stage separation, and will carry the capsule to an altitude of ~112 km. Cold gas jets were planned to be used for attitude control.

Crew Cabin Escape System

The design proposed four solid rocket engines in the second stage that could be fired at any time, even when the rocket stands on its launch pad. This constitutes an escape system, which can, in a case of an emergency, quickly separate the second stage from the rocket and propel it to an altitude of 1.5 km, where its parachutes can be deployed.

Rocket engine

The rocket engine was to use alcohol and liquid oxygen as propellants, and produces a maximum thrust of 254 kN, and burns for 55 s. It is constructed of low carbon steel, with propellant injectors made out of brass.

Flight profile

The Canadian Arrow rocket will launch vertically from the ground. Initial thrust is ~75.5 kN, but the rocket quickly reaches maximum thrust. After 55 s, the propellant is depleted and stage separation occurs. The solid fuel rockets in the second stage are ignited and boosts it up to an altitude of ~112 km, where the crew and passengers will experience a few minutes of "zero-G", or weightlessness.
After stage separation the first stage reaches an apogee of over 80 km before descent begins. Four parachutes slow the Canadian Arrow's first stage down before splashdown occurs at a speed of ~9 m/s, after which recovery of the spacecraft can take place.
During descent, the crew cabin was planned to use a ballute to reduce its speed. When its velocity becomes subsonic, the second stage's ballute was to be released and pull out the three parachutes before splashdown.

Testing

Canadian Arrow started as a team competing in the international X-Prize competition, with the ultimate goal of continuing past the X-Prize into the commercial sector providing private access to space. Funding during the X-Prize was provided by sponsorship and private investment.
In early 2003 the company would receive a major infusion of financial support by Canadian Arrow partner and Director of Spacecraft Development - Lou van Amelsvoort.
As a result, during the next two years The Company would also proceed to open the world's first private Astronaut training facility, continue vehicle development, and test propulsion and recovery systems.
Geoff Sheerin, president and CEO of Canadian Arrow, and Dr. Chirinjeev Kathuria announced on May 17, 2005, the creation of PlanetSpace Corporation. It is through this enterprise that Canadian Arrow will complete the construction of their space craft, and within 24 months offer suborbital space flight to aspiring space tourists. Planetspace expects to fly about 2,000 new astronauts within five years of operation. The price is expected to be $250,000 for each flight, including fourteen days of training. Cape Breton Island, in Nova Scotia is being considered as a launch site, and a contract has been signed with the government of Nova Scotia to provide of land for the project.
A requirement of the X-Prize for each participating company was to propose other possible markets for their spacecraft. Canadian Arrow coined the term "Spacediving", while investigating the possible use of Canadian Arrow spacecraft for a high altitude version of skydiving.
On November 11, 2005 Canadian Arrow teamed up with former X-Prize competitor Romanian aerospace company, ARCASPACE, to develop privately built spacecraft.
On December 15, 2005 PlanetSpace Corporation unveiled plans for an orbital commercial vehicle capable of carrying eight passengers. This vehicle to be called the Silver Dart is based on the U.S. Air Force's Flight Dynamics Laboratory-7 lifting body program from the 1970s.
PlanetSpace Corporation defunct as of 6 February 2013
On June 21, 2013 Blackburn news reported that the full scale engineering mock-up of the Canadian Arrow rocket was purchased by Sarnia Ontario's Preferred Towing. Having spent several years at Chris Hatfield Airport in Sarnia, Ontario, Preferred Towing expressed interest in hopes of restoring the rocket for display in Sarnia. This plan has since been scrapped and the mock-up no longer exists.
