The Cessna 152 is an American two-seat, fixed tricycle gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150, including a number of minor design changes and a slightly more powerful engine running on 100LL aviation gasoline.
The ERCO Ercoupe is a low-wing monoplane aircraft that was designed and built in the United States. It was first manufactured by the Engineering and Research Corporation (ERCO) shortly before World War II; several other manufacturers continued its production after the war.
- Tricycle landing gearwith castering nose wheel, steerable if desired
- Suitable longitudinal and lateral stability with limited up-elevator deflection, to prevent loss of control due to stalling and spinning.
- A glide-control flap
- Two-control operation using controls for pitch and roll.
SUBSONIC WIND TUNNEL
Majority of experimental data needed in aerodynamics is generated using wind tunnels. Wind Tunnel is a device for producing airflow relative to the body under test. Wind tunnels provide uniform flow conditions in their test section.
Applications of wind tunnels
- Drag Estimation
- Lift calculations
- Flight mechanics analysis
- Stability determination of models
- Non-Aero applications in
- Civil Engineering
- Automobile Engineering
- Calibration of instruments
JET ENGINE BAY
A jet engine is a reaction engine discharging a fast-moving jet that generates thrust by jet propulsion. This broad definition includes air breathing jet engines (turbojets, turbofans, ramjets, and pulse jets) and non-air breathing jet engines (such as rocket engines). In general, jet engines are combustion engines
In common parlance, the term jet engine loosely refers to an internal combustion air breathing jet engine. These typically feature a rotating air compressor powered by a turbine, with the leftover power providing thrust via a propelling nozzle — this process is known as the Brayton thermodynamic cycle.
- Analysis and Simulation Lab : This Lab enables the students gain a fair knowledge on design, analysis and simulation of aircraft structural parts, and also focuses on the practical learning of the simulation applications of the aircraft parts and sub systems. In addition to this, it helps us in examining the different parameters and factors affecting its performance.
