Hindustan University, one of the top university in India is proud in sharing with you the participation of our students in NASA Contest 2009 - 2010.

Project Title : DESIGN OF A ROTOR COMBINED SUB-SONIC TILT ROTOR

How did we come to know about the contest?
While surfing the net, we found that NASA has been conducting a Tilt Rotor Design Competition 2009-2010 for students in high school level as well as college level in two levels namely
* U. S Category
* Non U. S Category

We noticed that the contest is mainly based on innovative and creative team work including a faculty advisor. Also found that only U. S Category Team Winners are eligible for cash price and internships at NASA. The rest all will receive trophies and certificates. After understanding the problem statement mentioned in the NASA Website, we decided to participate in the competition and discussed the contest with Prof. P. S. Venkatnarayanan and selected him as the faculty advisor for our design project.

Problem Description:
To design a tilt rotor for rescue operations while natural calamities like Tsunami, Hurricane and Forest Fires when roads, runways, railways, and harbors are damaged.

Amphibious Tilt rotor Design Goals
* Cruise speed: 300 knots
* Design range: 800 nm

Capabilities
* Take-off from water or ground; land on water or ground. Water includes lakes and oceans.
* Carry up to 50 passengers
* Siphon water into an internal tank and expel water while airborne operations

To submit a conceptual design for an amphibious tilt rotor that meets or exceeds the design goals and capabilities described above. Describe the technical issues associated with water landings and take-offs.
First Approach:
During the 6th and 7th semester of our Aeronautical Engineering programme, we had to work on the Aircraft Design Project (ADP 1 and 2). The experience gained in designing the project helped us to to proceed with the project in hand with ease.
We also spent days in library and had gone through several books mainly on Aerodynamics, Engines Propulsion etc, which helped us to understand the tilt rotor working principle. We collected materials regarding tilt rotor design and operation, and also got information through you tube videos.

Consultants:
We have discussed the problem statement with our faculty members Prof. P. S. Venkatnarayanan and Dr. P. K. Dash. They guided us whenever we required help.

Design Stage:
We were thinking on for months about tilt rotor, searched and collected all the information regarding the contest for about 3 months and preserved the data. Finally we prepared our report mainly containing. Courtesy: Hindustan University, One of the Top Universities in India
1. Design Phase In which we proposed the initial design objectives and briefly discussed the various design stages.
2. Airfoil Selection Selection of 6 digit NACA airfoil.
3. Wing, and Fuselage Selection
4. Flight Controls Use of elevons and discussed pitch, roll and yaw controls.
5. Float Actuation
6. Weight Estimation and Performance Calculations.
7. 3D Image and Design Image.
Includes hand drawings and design image created using CATIA software.

Specifications:
* Cruise speed: 300 knots
* Design range: 800 nm
* Take-off from water or ground; land on water or ground.
* Carry up to 50 passengers.
* Siphon water into an internal tank and expel water while airborne operations

Advantages:
* Vertical takeoff and landing.
* A long time hovering is possible; thereby it can perform better rescue operations.
* Belly itself acts as a float for landing and takeoff in water, also incorporated special floats which further helps in emergency.
* Multi-mission is possible thereby can be used in Defense & Navy
* High altitude and range compared to Helicopter.
* Constructed using advanced composites thereby high reliability

Working of the design:
The tilt rotor we have designed consisting of three engines. Two engines are located at the wings acting as tilt rotors during operations and one engine at the front performs helicopter operation. While cruise the rear engines are tilted using hydraulic power like normal aircraft. During take-off, landing, and hovering all three engines are in vertical position in order to give lift.

How can it be useful for our country?

Natural calamities like,
* Earthquake (E.g. : Gujarat)
* Tsunami (South Indian Coasts)
* Flash floods(E.g. : Kashmir)
* Floods in North East Regions like Bihar, Orissa, Assam
* Forest Fires etc.
* Searching of fishermen in accident especially in Tamil NADU.

Man made disasters like,
* Bhopal gas tragedy in Bhopal
* Nuclear Radiation

Defense:
Army to work in mountain regions like Himalayas and North East Regions.
To carry troops in emergency condition like 26th December bomb blast.

Navy Operations:
* Rescuing fishermen while at storms in oceans and border problems
* Night Patrol
* Coastal Security

Air Force Operations:
* Mainly at hill stations to assist other forces.

Final Stage:
We designed the tilt rotor as per the rules of FAA, AIAA, and ICAO and prepared the design report and attached the necessary requirements regarding the team and faculty including the design image and send it to NASA. Courtesy: Hindustan University, One of the Top Universities in India

Results:
Finally NASA has published the results of Tilt Rotor Design Competition 2009-2010 by 4th week of June in which they have mentioned that over hundreds of teams have participated in the contest and our team has secured the highest score in Non U. S Team Level. The results were published in the NASA Official Website and our Team has won the honors under Non U. S Category. Our team image, concepts image and abstract are published in NASA Website. Our team has received trophies and certificates from NASA also.
* We have also applied for patent right of our design.
