Falcon 9 | How Many Falcon 9 Rockets Are There?:  Since June 2010, the Falcon 9 family of rockets has launched 151 times, with 149 full mission successes, one partial failure, and one spacecraft catastrophic loss.

In addition, during the fuelling procedure, one rocket and its cargo were destroyed on the launch pad before a static fire test was scheduled.

On June 4, 2010, Falcon 9 successfully launched for the first time, and on December 8, 2010, f 9 successfully launched for the second time

Facts to Know:

“SpaceX designed, produced, and tested all structures, engines, avionics, and ground systems in the United States”

The Dragon spacecraft is 48.1 meters (157 feet) tall, and the Falcon 9 is 48.1 meters (157 feet) tall. In a vacuum, the vehicle from the COTS 2 flight can generate one million pounds of thrust.

Falcon 9 Is the Vehicle of Choice

For business and government customers due to its cutting-edge technologies. Approximately 40 Falcon 9 launches are scheduled by SpaceX.

The number 9 alludes to the nine Merlin engines that power the first stage, while the number 1 refers to the Merlin vacuum engine that drives the second stage.

Designed From the Start to Safely Transport Crew

  • On its first two flights, the mission was 100% successful (June 2010 and December 2010).
  • The first rocket was created in the twenty-first century; developed from the ground up for less than $300 million in four and a half years (November 2005 to June 2010).
  • For optimal dependability, an advanced design is used. The Falcon 9 has a straightforward two-stage architecture that reduces separation events, with nine engines on the first stage.

It can still finish its mission safely even if one of the engines fails. Stage separation incidents and engine failures are the most common causes of launch failures.

The Initial Stage

The walls of the Falcon 9 tank are built of an aluminum-lithium alloy. Friction-stir welding, the strongest and most dependable welding technology available, is used to construct the tanks at SpaceX.

  • The Falcon 9 first stage is powered by nine SpaceX Merlin regeneratively cooled engines.
  • Falcon 9 is kept down and not released for flight until all propulsion and vehicle systems are certified to be operating normally after the first-stage engines have been ignited.
  • F 9 interstage is a composite structure with an aluminum honeycomb core and carbon fiber face sheets that joins the upper and lower stages.

Falcon 9 employs an all-pneumatic stage separation technology similar to Falcon 1’s.

The Second Phase

The Falcon 9’s second-stage tank is essentially a scaled-down version of the first-stage tank, employing many of the same tooling, materials, and production procedures.

As a result, car production costs are reduced significantly. The Falcon 9 top stage is powered by a single Merlin engine.

The engine incorporates dual redundant pyrophoric igniters that use triethylaluminum-triethyl borane for increased restart reliability (TEA-TEB).

Merlin Is a Type of Engine

  • The first stage of the F9 is powered by nine Merlin engines, while the second stage is powered by one Merlin engine. In a vacuum, the nine Merlin engines provide one million pounds of thrust.
  • The Merlin engine was built in-house at SpaceX, but it is based on a long line of space-proven engines.
  • Merlin’s pintle-style injector was originally employed in the Apollo program for the lunar module landing engine, one of the mission’s most essential phases.

The turbopump also provides the hydraulic actuators with high-pressure kerosene, which is recycled into the low-pressure intake.

This design method eliminates the need for a separate hydraulic power supply, making it impossible for thrust vector control to fail due to a lack of hydraulic fluid.

The turbopump’s third function is to regulate roll by activating the turbine exhaust nozzle (on the second-stage engine).

The system-level reliability is significantly improved by combining three functions into one device that can be verified as working before the vehicle is authorized to take off.

Reliability

  • Falcon 9 must perform successfully once more before the spacecraft can reach orbit.
  • In the first three flights, 75% of the world’s existing launch vehicle families have suffered at least one failure.
  • Engine failures, stage separation failures, and, to a lesser extent.
  • Avionics difficulties accounted for 91 percent of known launch failures between 1980 and 1999, according to Aerospace Corporation’s study.
  • The vehicle’s first stage is made up of nine Merlin engines grouped, allowing it to survive an engine loss while still completing its mission.

*This is an enhanced version of the architecture used by the Apollo Program’s Saturn V and Saturn I rockets, which achieved perfect flight records despite losing engines on several flights.

Limits Complications Connected With Separation Events

  • By having only two stages. SpaceX also boasts a cutting-edge avionics system.
  • SpaceX employs a hold-before-release technology, which is standard on commercial airplanes but not on many launch vehicles.
  • The Falcon 9 is held down and not released for flight until all propulsion and vehicle systems are certified to be operating normally after the first-stage engine ignites.
  • If any difficulties are discovered, an automatic safe shut-down occurs, and propellant is emptied.
