Know Your Airplane

Know Your Airplane Airplane fascinates us all. An Airplane is an icon of Extreme Engineering, Beauty and Royalty. The history of airplane started long time ago.

From ancient time people desired to fly like birds. They tried so many ways, had various ideas to fly. But in 1903 the 'Wright Brothers' were first to fly. From that day, the journey of Airplane begins...

The stabilized tracking video showcases the Ax-2 booster executing the historic first-ever Return to Launch Site (RTLS) landing after a Crew Dragon launch. For those who have never witnessed a Falcon 9 in person, the video demonstrates a remarkable sight of a 13-story building equivalent soaring through the air.

“এক্স-২ বুস্টারের স্থিরভাবে ট্র্যাকিং করা ভিডিওতে দেখা যাচ্ছে কিভাবে ক্রু ড্র্যাগন লঞ্চের পর প্রথমবারের মতো একটি রিটার্ন টু লঞ্চ সাইট (RTLS) ল্যান্ডিং অভিযান সফলভাবে সম্পন্ন হচ্ছে। যারা ফালকন ৯ নিজেই দেখেননি তাদের জন্য এই ভিডিওতে দেখা যাচ্ছে একটি ১৩-তলা বিল্ডিং মতো আকাশে উড়ছে।”

CEOs of airlines that operate the Embraer E195-E2 say this about the airplane:

--"Embraer E195-E2 is virtually unchallenged in the 120-to-150-seat medium-haul segment"

--"E195-E2 the most fuel efficient lowest emission aircraft in its class"

--“We are actually getting better fuel performance then we had even anticipated. It gives us flexibility to connect dots that had never been connected before; long routes that have never been plumbed before, just hundreds of possibilities. We can also add additional frequencies in our business markets. That is nirvana for the airline business. Very exciting airplane.”

With ~150 seats, 5 tonne cargo capacity, ~5000 km range, and unbeatable fuel efficiency, the E195-E2 can disrupt the competitive landscape for airlines.

As its already doing for its operators.

Engine Installation using Bootstrap tool

The engine installation procedure with the bootstrap system consists of two main phases:
–The lifting phase is the operation dedicated to lift up the engine from the ground to the pylon. This phase stops when the engine mounts start to enter in the pylon shear pins.
–The approaching phase is the operation dedicated to engage the pylon shear pins in the engine mount and to have contact between engine mount and the pylon.

The bootstrap system is equipped with needle dynamometers indicating the applied loads. The approaching phase is sensitive because the technicians have to continuously monitor the loads applied on the bootstrap system. Several mechanics, working as a unit, are required to perform this operation. They have to ensure proper communication amongst the team in order to ensure a balanced bootstrap movement and an adequate load monitoring at all times. An overload may cause a life threatening structural failure of the bootstrap

The necessity for CFD-based aerodynamics prediction :

👉 For rotors operating in edgewise flight, the retreating blade may experience dynamic stall (at high speed) that is characterized by a rapid reduction in lift and reduction in pitching moment.

👉 As the forward speed increases, the advancing blade operates in transonic regime (due to increased velocity) and can encounter shocks, while the retreating blade can suffer from dynamic stall.

👉 Ultimately the dynamic stall is the limiting factor which puts a limit on the top speed on a helicopter.

👉 The wake of a moving rotor is complex causing significant aerodynamic interaction between the rotor system and the fuselage.

👉 The wake system is comprised of vortices which stem from the pressure-equalizing effects at the blade root and tips. They are more pronounced at the blade tips.

👉 These vortices induce a velocity field according to the Biot-Savart law.

👉 The vortices coming off from each blade interact with each other and with the following blades giving rise to blade-vortex and wake-vortex interactions and have a significant impact on the aerodynamic loading on the rotor.

👉 This directly impacts the performance of the helicopter and noise characteristics.

👉 Wonder why those choppers make the “wop-wop” noise, thanks to the blade and vortex interactions!

👉 It is paramount for finite volume Computational Fluid Dynamics (CFD) methods using the right mesh, physics, and cell sizes to accurately capture these tip vortices without which the estimation of rotor performance is difficult.
