The document presents an overview of reusable launch vehicles (RLVs), focusing on SpaceX's Falcon 9, which aims to revolutionize space access through reusability. Spacex, founded by Elon Musk, champions affordable and routine space travel, with Falcon 9 designed to reduce launch costs significantly. Key technological features include liquid oxygen fuel, advanced engine design, and vertical landing capabilities for reusability.

1. A technical presentation on
REUSABLE LAUNCH VEHICLE

2.  A reusable launch vehicle (RLV) refers to vehicle which
can be used for several missions.
 A fully reusable vehicle has never been done before.
That really is the fundamental breakthrough needed to
revolutionize access to space.
 The main advantage of an RLV is it can be used
multiple times, hopefully with low service cost and
make space travel more accessible.

3.  The company established in 2002 by ELON MUSK, the
founder of Tesla Motors, Paypal and the Zip2
Corporation.
 To make space flight routine and affordable, and to
make human a multi-planet species.
 SpaceX offers a Falcon family of launch vehicles that
improve launch reliability and increase access to space.

4.  Falcon 9 is a family of two-stage-to-orbit launch
vehicles, named for its nine engines, designed and
manufactured by SpaceX.

5.  Falcon 9 is a two-stage launch vehicle powered by
liquid oxygen (LOX) and rocket-grade kerosene(RP-1)
 F9R first launch was on Dec 21st 2015 and successful
landing of its first stage.
 On 30th March 2017 it was launched by reusing its first
stage reduced the cost by 40%

7.  The first stage of the F9 featuring stretched propellant
tanks and a modified engine compartment.
 The first stage tank walls are made from aluminum-
lithium alloy to provide maximum strength.
 The first stage uses Liquid Oxygen oxidizer and Rocket
Propellant-1 as fuel which is highly refined Kerosene.

8.  Merlin 1D Rocket Engine is used improved
manufacturing and quality control techniques to
enable SpaceX to produce a greater number of engines
per year while reducing overall risk.

9.  The overall goal of F9R is to make the first stage fully
re-usable by returning them to the landing site
vertically.
 The four deployable landing legs and four grid fins
used for three-axis control.
 Cold gas N2 thrusters are used to rotate the booster
into direction of landing site.

13.  The vehicle requires extensive inspection and
refurbishment.
 Each and every part of the launch vehicle needed to be
individually inspected.
 Main engines needed to be removed to undergo
extensive inspection and overhaul.

15.  As this is the 1st reusable launch vehicle ever used is the pivotal
breakthrough needed to substantially reduce the cost of space access.
 Falcon 9R is being said to be used in human MARS mission in 2020.
 In a single launch F9R can put 15 satellite of orbit of each 0f 200kg.
 As being said the in future when a colony will be formed in MARS the
transportation for human beings are being carried out of next versions
of FALCON launch vehicle as said by the SPACEX CEO.

16.  Reusable Launch Vehicle is the fundamental
breakthrough needed to revolutionize access to space.
 To make spaceflight routine and affordable, and to
make humans a multi-planet species.
 A reusable system has extremely low direct operating
costs. A future reusable launch vehicle should be
constructed within low cost.
