Q. Consider the following statements regarding the delta wing configuration of the LCA Tejas:
  1. The aircraft can fly at supersonic speeds without being significantly affected by the shock wave.
  2. The aircraft can easily fly at lower as well as higher altitudes due to the delta wing configuration.
  3. The delta wing design leads to significant energy and fuel savings compared to other configurations.
Which of the above statements is / are correct?

Answer: Only 1
Notes: Statement 1 is correct because delta wings are particularly suited for supersonic speeds by delaying shockwave formation. Statement 2 is not correct, as the ability to fly at varied altitudes is not primarily determined by wing configuration. Statement 3 is incorrect since delta wings do not inherently increase fuel efficiency; they are chosen for aerodynamic advantages at high speeds.
