The Rocket Racing League was [1] a racing league that planned to use rocket-powered aircraft to race a closed-circuit air racetrack. Founded in 2005, the league made its first public flights in 2010 and was working to begin regular racing seasons. The "Rocket Racers" were slated to compete in the air and on a virtual racetrack easily viewed by a live audience as well as projected on large screen and handheld electronic displays.
Three prototype canard-style Rocket Racer aircraft were built between 2006 and 2010. The league had planned to hold its inaugural race season in 2008 with four races, but encountered financial difficulties that delayed fielding of Rocket Racers by the six teams that had been previously announced. With the addition of venture capital funding in mid-2009, technology development continued and one exhibition occurred in 2010, with another round of plans for an inaugural season of races in 2011. The 2011 races were never scheduled and the league was defunct by 2014. [2]
Projected to be an hour and one half in length, the races were intended to be between Rocket Racer planes that used liquid oxygen and either kerosene or ethanol fuel [3] with a burn time of four minutes. The rocketplanes were expected to cost less than US$1 million each. The planes were based on the fixed-gear Velocity SE modified by XCOR Aerospace and the retractible gear Velocity XL modified by Armadillo Aerospace for the purpose of rocket racing. The Velocity airframe was derived from a commercially available kit plane that traced its design heritage to the Rutan Long-EZ, which had been modified to accept rocket power and custom avionics. In order to provide the airframes, RRL purchased the aircraft's manufacturer, Velocity Aircraft, in April 2008. [4]
The RRL had been called "NASCAR with rockets", XCOR Aerospace flew the Rocket Racer for a public audience at the 2008 EAA AirVenture Airshow at Oshkosh, Wisconsin. [5] [6] If league competition were to begin, Whitelaw indicated tournament semifinals would be held each September in Nevada, with finals each October in New Mexico at the X Prize Cup competing for a $2 million championship purse.
Races were to have taken place on a race course two miles (3 km) long, one mile (1.6 km) wide, and 1,500 feet (460 m) in the air. A typical race would take about one hour, and fans would be able to see multiple camera views, including cockpit, "on-track," "side-by-side" and wing-angle views.
Additionally, a computer game had been planned which was to have interfaced with racer positional data in real time over the internet, allowing players to virtually compete with the rocket pilots.
The proposed "track" for a typical Rocket Race was to have begun with a staggered start. Pilots were to take off in pairs a few minutes apart, they would be competing against the clock but would maneuver around each other much like NASCAR. The pilots would be guided by a virtual three-dimensional "track" projected in their head-up display. Each racer was to have a separate track to follow but the courses were planned to be close together to build excitement.[ citation needed ]
As of 2008 [update] , there were six teams registered to compete in the inaugural 2008 race season, Rocket Star Racing, Team Extreme Rocket Racing, Canada-based Beyond Gravity Rocket Racing, Bridenstine Rocket Racing, Santa Fe Racing and Thunderhawk Rocket Racing. [6]
As of 2012 [update] , RRL claimed that "official team recruitment will commence as the production-level Rocket Racers near completion", listing five "candidate teams of the RRL franchise": Bridenstine Rocket Racing, Santa Fe Racing, Rocket Star Racing, Team Extreme Rocket Racing, and Canada-based Beyond Gravity Rocket Racing. [7]
The formation of the league was announced by Granger Whitelaw, and Peter Diamandis, founder of the Ansari X-Prize, in October 2005 [8] in partnership with the Reno Air Races.[ citation needed ] According to Diamandis, the purpose of the league was to "inspire people of all ages to once again look up into the sky and find inspiration and excitement."[ citation needed ]
Initial plans called for a four-team league finals in 2006, to be followed by 10 teams competing in 2007, with video games based on the competition also out in 2007. [8] In 2006, analysts identified doubts about the economics of the venture, and especially of the ability of RRL to attract a large fanbase similar to IndyCar and NASCAR. [9] In the event, no races occurred in either 2006 or 2007.
In April 2008, the league stated that it was "ready for competition [announcing] four exhibition races will be held later [in the] year, one in Las Cruces." [10]
On April 14, 2008, the Racing Rocket Racing Composite Corporation, a subsidiary of the Rocket Racing League, acquired Velocity Aircraft. The RRL announced their goal was to "produce an airframe that will be consistent for all competing Rocket Racers." [11]
On May 26, 2010, a Velocity employee posted to the builder's email-list a note from Scott and Duane Swing that stated that they had bought back full ownership of Velocity Inc from Rocket Racing League. The RRL now owns no share of Velocity Inc. [12]
None of the four planned 2008 races were actually run. The Rocket Racing League had difficulty in attracting and retaining sufficient financial backing, from both investors and sponsors, in order to get an initial racing season firmly scheduled in 2008, 2009, or 2010. Some progress with the rocket and aircraft technology continued however, but by 2014, the league had gone defunct. [2]
The league twice failed to complete construction of six hangars contracted to be built on land adjacent to Spaceport America near Las Cruces, New Mexico. As of January 2009, the league was at risk of having their leases with the City of Las Cruces terminated. [13]
In July 2009, the league announced the closing of a venture capital financing round of US$5.5 million. The funds were to be used for ongoing operations and for the development of a next-generation Rocket Racer. [14]
As of February 2010 [update] , Peter Diamandis suggested that 2010 could be the year that we see "more than one racer in the air and possibly in exhibition races." Non-exhibition "live" races were to occur as early as 2011. [15] Also in February, the Tulsa Air and Space Museum and Planetarium (TASM) announced that it would partner with the Rocket Racing League to host an exhibition flight of a Rocket Racer at the QuikTrip Air and Rocket Show at Tulsa International Airport in April 2010. [16]
The Rocket Racing League announced a "2010 World Exhibition Tour" on April 24, 2010, when they unveiled their Mark-III X-racer rocket plane at the QuikTrip Air & Rocket Racing Show in Tulsa, Oklahoma. The RRL exhibition flights at Tulsa were the first simultaneous flights of two rocket-powered airplanes in the history of peacetime aviation. RRL duplicated this historic feat later that day. The league's intent in such exhibitions was to "build up the league's fan base, in addition to perfecting operations and technologies, before the league's official launch in 2012." [17] The April event in Tulsa was the only RRL exhibition of 2010.
The league's financial difficulties continued in 2011 and no races were organized. [18]
By 2014, persons formerly involved with the league had made public statements that the league had failed and was now defunct. [2]
The Rocket Racing League had been developing prototype Rocket Racers since 2006, working with one airframe manufacturer and two rocket engine producers on three prototype aircraft to date. All three of the airframes have been of the canard configuration to more easily accommodate the rocket propulsion technology.
A fifth model was proposed, but not built, in 2011: the Mark-V X-Racer. [18]
XCOR Aerospace developed the XCOR EZ-Rocket, later flown under Rocket Racing League sponsorship as an X-Racer prototype rocketplane. First flight was July 21, 2001 at Mojave Airport in Mojave, California. [19] This XCOR technology demonstrator was a converted Rutan Long-EZ and, in its final version, utilized two 400 lbf (1.8 kN) thrust XCOR Aerospace isopropyl-alcohol-powered rocket engines [9] of engine type XR-4A3. [20] XCOR flew the EZ-Rocket for several years in development and demonstration flights, including, in collaboration with the RRL, at the 2005 X-Prize Cup in New Mexico. [9]
By 2006, the design-point for the RRL racer had become a single rocket engine utilizing kerosene as the rocket fuel, carrying 1,000 lb (450 kg) of liquid oxygen in its flight oxidizer tank. [9]
The first RRL prototype built, known as the Mark-I X-Racer, was built on a Velocity SE airframe and was also powered by XCOR Aerospace rocket technology, a regeneratively-cooled and pump-fed XR-4K14 rocket engine. [20] This rocket-powered aircraft flew several demonstration flights at the 2008 EAA AirVenture Oshkosh air show. [21] The total thrust for the single-engine Mark-I X-Racer was 1,500 lbf (6,700 N), [9] approximately twice that of the EZ-Rocket.
As of 2010 [update] , the Rocket Racing League was utilizing a highly modified Velocity XL fixed-gear airframe and an Armadillo Aerospace 2,500 pound thrust liquid oxygen (LOX) and ethanol rocket engine in both its Mark-II X-Racer and Mark-III X-Racer demonstration vehicles. [22] The Mark-II and Mark-III racers could take off just 4 seconds after the rocket engine was ignited; both vehicles were limited to a top speed of 300 mph (480 km/h). [23] The rocket engine was a LOX-Ethanol, film-cooled, pressure-fed, blow-down [24] design with a 10 to 15-foot (4.6 m)-long exhaust plume. Plume-seeding technology allowed the plume color to vary from red to green to yellow to better facilitate race spectators in keeping track of specific racers while in the air. [23]
The Mark-II (N205MB) racer utilized a standard fixed-gear XL airframe, modified for the addition of the Armadillo rocket propulsion. The Mark-III (N133XP) airframe was modified during manufacturing at Velocity Aircraft explicitly for use as a Rocket Racer, with canopy top, center seat and control stick, and other enhancements. [22]
The Mark-V proposed design resembles "a sleek, rocket-powered sailplane" and may be built at Velocity Aircraft, although no firm contracts are in place to do so as of November 2011 [update] . [18]
Armadillo Aerospace was an aerospace startup company based in Mesquite, Texas. Its initial goal was to build a crewed suborbital spacecraft capable of space tourism, and it had also stated long-term ambitions of orbital spaceflight. The company was founded by John Carmack, co-founder and former chief technical officer of id Software.
Elbert Leander "Burt" Rutan is a retired American aerospace engineer and entrepreneur noted for his originality in designing light, strong, unusual-looking, and energy-efficient air and space craft. He designed the record-breaking Voyager, which in 1986 was the first plane to fly around the world without stopping or refueling. He also designed the Virgin Atlantic GlobalFlyer, which in 2006 set the world record for the fastest and longest nonstop non-refueled circumnavigation flight in history. In 2004, Rutan's sub-orbital spaceplane design SpaceShipOne became the first privately funded spacecraft to enter the realm of space, winning the Ansari X-Prize that year for achieving the feat twice within a two-week period.
Richard Glenn Rutan was an American military aviator and officer. He was also a record-breaking test pilot who in 1986 piloted the Voyager aircraft on the first non-stop, non-refueled around-the-world flight with co-pilot Jeana Yeager. Rutan was born and raised in Loma Linda, California, where he gained an interest in flying at a young age. He was the older brother of famed aerospace designer Burt Rutan, whose many earlier original designs Dick piloted on class record-breaking flights, including Voyager.
Richard Alan "Rick" Searfoss was an American aviator who was United States Air Force colonel, NASA astronaut and test pilot.
The Mojave Air and Space Port at Rutan Field is in Mojave, California, United States, at an elevation of 2,801 feet (854 m). It is the first facility to be licensed in the United States for horizontal launches of reusable spacecraft, being certified as a spaceport by the Federal Aviation Administration on June 17, 2004. The facility covers 2,998 acres and has three runways.
The Rutan Model 61 Long-EZ is a tandem 2-seater homebuilt aircraft designed by Burt Rutan's Rutan Aircraft Factory. The Long-EZ has a canard layout, a swept wing with wingtip rudders, and a pusher engine and propeller. The tricycle landing gear has fixed main wheels with streamlined spats and a retractable nosewheel. Its predecessor was the VariEze, plans for which were first available to homebuilders in 1976. The prototype Long-EZ, N79RA, first flew on June 12, 1979.
A rocket-powered aircraft or rocket plane is an aircraft that uses a rocket engine for propulsion, sometimes in addition to airbreathing jet engines. Rocket planes can achieve much higher speeds than similarly sized jet aircraft, but typically for at most a few minutes of powered operation, followed by a gliding flight. Unhindered by the need for oxygen from the atmosphere, they are suitable for very high-altitude flight. They are also capable of delivering much higher acceleration and shorter takeoffs. Many rocket aircraft may be drop launched from transport planes, as take-off from ground may leave them with insufficient time to reach high altitudes.

The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed the combustion chamber pressure.
XCOR Aerospace was an American private spaceflight and rocket engine development company based at the Mojave Air and Space Port in Mojave, California, Midland International Air and Spaceport in Midland, Texas and the Amsterdam area, the Netherlands. XCOR was formed in 1999 by former members of the Rotary Rocket rocket engine development team, and ceased operations in 2017.
The Velocity Model 173 SE (Standard Elite) is an entry-level canard pusher aircraft from Velocity Aircraft. The four seat, rear engine aircraft may be powered by a 160 hp (120 kW) Lycoming IO-320 or a 200 hp (150 kW) Lycoming IO-360 engine.
The Velocity XL is an American amateur-built aircraft, produced by Velocity, Inc. It is an enlarged version of their Velocity SE canard pusher design.
The XCOR EZ-Rocket was a test platform for the XCOR XR-4A3 rocket propulsion system. The airplane was a modified Rutan Long-EZ, with the propeller replaced by first one, then later a pair of pressure-fed regeneratively cooled liquid-fueled rocket engines and an underslung fuel tank. The engines were restartable in flight, and were contained within Kevlar armor shielding. The EZ-Rocket was registered as an experimental aircraft.
The X Prize Cup is a two-day air and space exposition which was the result of a partnership between the X Prize Foundation and the State of New Mexico that began in 2004 when the Ansari X-Prize was held. This led to plans to build the world's first true rocket festival. Three X-Prize Cups have been held: in 2005, 2006 and 2007. Each X Prize Cup hosts different events and demonstrations, such as rocket-powered bicycles, rocket jet packs; but particularly notable are the Lunar Lander Challenge and the Space Elevator Games. 85,000 visitors attended the 2007 X Prize Cup. Although there was no X Prize Cup in 2009, there was a Lunar Lander Challenge.
The XCOR Lynx was a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane that was under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. The Lynx was intended to carry one pilot, a ticketed passenger, and/or a payload above 100 kilometres (62 mi) altitude. The concept was under development since 2003, when a two-person suborbital spaceplane was announced under the name Xerus.
Velocity, Inc. is an American kit aircraft manufacturer.
RocketShip Tours is an American space tourism company founded in 2008 by travel industry entrepreneur Jules Klar and which planned to provide sub-orbital human spaceflights to the paying public, in partnership with rocketplane developer XCOR Aerospace. Klar created RocketShip Tours to act as General Sales Agent for XCOR Aerospace.
James Frederick Bridenstine is an American military officer and politician who served as the 13th administrator of the National Aeronautics and Space Administration (NASA). Bridenstine was the United States representative for Oklahoma's 1st congressional district, based in Tulsa from January 3, 2013, to April 23, 2018. He is a member of the Republican Party. Bridenstine currently works in the private sector and holds positions at Voyager Space Holdings, Viasat, Acorn Growth Companies and Firefly Aerospace.
Although the Rocket Racing League held demonstration flights at a 2010 air show in Tulsa that Bridenstine helped organize, the venture failed to take off. 'It was before its time,' [Bridenstine] lamented
"blow-down" mode: without external helium pressure, relying solely on helium pumped into the smaller internal propellant tanks [which limits] duration.
